Please add file association settings like explained at https://github.com/angelozerr/lsp4xml/wiki/Configuration#file-associations

• file associations
• catalogs
• server vm arguments
• proxy support
• formatter settings
• cached data

expose a new xml.validation.noGrammar preference, with valid values being ignore|hint|info|warning|error. See eclipse/lemminx@8ae6fc6.

• update package.json
• update readme
• update wiki

When I hover on a pom.xml I see the hover content as Unsupported Markup content received. Kind is: undefined.

In my case I have an installed java but not a JAVA_HOME. My java path is in my Windows PATH variable.

To use this java without configuring VSCode preferences, you could search it:

• with where java command in OS Windows
• with which java command for other OS.

This idea was done in Eclipse Bluesky to find the node process. Here the Java code:

public static String getNodeJsLocation() {
		String res = "/path/to/node";
		String[] command = new String[] {"/bin/bash", "-c", "which node"};
		if (Platform.getOS().equals(Platform.OS_WIN32)) {
			command = new String[] {"cmd", "/c", "where node"};
		}
		BufferedReader reader = null;
		try {
			Process p = Runtime.getRuntime().exec(command);
			reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
			res = reader.readLine();
		} catch (IOException e) {
			Activator.getDefault().getLog().log(
					new Status(IStatus.ERROR, Activator.getDefault().getBundle().getSymbolicName(), e.getMessage(), e));
		} finally {
			IOUtils.closeQuietly(reader);
		}

		// Try default install path as last resort
		if (res == null && Platform.getOS().equals(Platform.OS_MACOSX)) {
			res = "/usr/local/bin/node";
		}

		if (res != null && Files.exists(Paths.get(res))) {
			return res;
		} else if (!alreadyWarned){
			warnNodeJSMissing();
			alreadyWarned = true;
		}
		return null;
	}

It should be cool to adapt this Java code in TypeScript and to discover java instead of node.

When editing pom.xml file with an error, the error message showed by XML extension is very hard to read.

It's too long
It has too much information and unnecessary details
It does not provide clear action items

Please consider improve the message by:

1. Remove all the namespaces before the actual element names: e.g. {"http://maven.apache.org/POM/4.0.0":name2} -> name2
2. Incorporate proper formatting/coloring to improve readability
3. Check similarity of the node name and rank the most possible one on top

Sample:

[XML] Invalid content was found starting with element 'name2'.
Possible values:
-> name
description
packaging
url
...

Code completion is "one off" in some places of the XML file in the attached mini.zip.

At this position it should suggest edmx:Include and edmx:IncludeAnnotations, instead it suggests nothing:

Instead it shows these suggestions when triggering code completion one level up in the XML tree (where it should instead suggest edmx:Reference and others):

To make things more confusing this only happens with suggestions for the "outer" XSD (here: edmx). Suggestions for elements in the "inner" XSD (here: edm) work fine - only edm:PropertyRef is allowed and suggested here:

To make things even more confusing the "one off" suggestions only show when pressing Control-Space on "white space". Once I type a < the correct suggestions show:

Follow,

https://github.com/redhat-developer/vscode-java/blob/master/src/extension.ts#L374

https://github.com/redhat-developer/vscode-java/blob/master/src/extension.ts#L351

to notify the user to disable the setting

... also mention the incompatibility between autoclose tag and brackets

... when not typed within an attribute value

I have XML files that use an "outer" namespace which in turn imports an "inner" namespace.

If the "inner" namespace is declared as the default namespace via xmlns="...", code completion works fine in the "outer" and the "inner" part, e.g.:

However if the "inner" namespace is declared with a namespace prefix via xmlns:edm="...", code completion for constructs in the "outer" namespace also shows top-level elements from the "inner" namespace that are not allowed by the "outer" XSD in that place:

This effect only shows on "level 1", i.e. directly below the root element of the "outer" namespace, where no elements of the "inner" namespace are allowed at all.

On "level 2", i.e. within children of the root element, code completion works fine and only shows allowed elements.

Test project is attached: vscode-xml-catalog-test.zip

• examples/mini-catalog.xml works as expected
• examples/mini-catalog-prefix.xml has the above strange behavior in one place.

Similar to the html support in vscode, hitting enter in a xml tag should automatically indent the content.

No idea how it's implemented in the html extension. It's probably a client-side feature, but not necessarily.

Originally reported here: eclipse/lemminx#111

I am trying to get autocompletion while authoring an XSD.
For this, I declared the XSD as an instance of the XSD meta schema:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified"
           elementFormDefault="qualified"
           xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.w3.org/2001/XMLSchema
                               http://www.w3.org/2001/XMLSchema.xsd">

</xs:schema>

However, I am not getting any autocompletion or hovers.

If I rename the file to have a .xml extension, it works as expected.

It would be great if the extension didn't depend on specific file extensions, but just checked if the file started with a <?xml declaration, because there are many files that are XML but don't use a .xml extension, e.g. .xsd, .ps1xml or .csproj.

Output channel log:

Sep 10, 2018 2:18:30 PM org.eclipse.lsp4xml.XMLLanguageServer initialize
INFO: Initializing LSP4XML server

(no errors)

Version: vscode-xml-0.1.0-199.vsix

Currently, when an xsl document is opened, it gets no XML support whatsoever, as it's set as its own language in vscode.
See WhatIsXSL-example.xsl.zip from https://www.w3.org/Style/XSL/WhatIsXSL.html

Given:

<foo>
    <bar>
     // press ctrl-space here
</foo>

There's no completion until I press <. While I understand autocompletion is triggered on <, explicit completion requests (ctrl+space), should also return results from anywhere in the document. In this case, it should return </bar>.
The current behavior is very frustrating.

This may be a server-side issue (or not). cc @angelozerr

Extension doesn't start with Java 9/10. MAYBE needs to add module/opens flags as in https://github.com/redhat-developer/vscode-java/blob/6f16de69371a8ed9684ba8793e289df6750d1423/src/javaServerStarter.ts#L46-L52

so actually the java version parsing used in https://github.com/gorkem/vscode-xml/blob/master/src/requirements.ts is outdated, doesn't recognize Java 10. See https://github.com/redhat-developer/vscode-java/blob/6f16de69371a8ed9684ba8793e289df6750d1423/src/requirements.ts for a better solution

Use the preference name spaceBeforeEmptyCloseTag.

When formatting document with the xml-stylesheet processing instruction,
it removes all attributes, except version and encoding.

Example:
<?xml-stylesheet href="my-style.css" type="text/css"?>
becomes
<?xml-stylesheet?>

However,
<?xml-stylesheet href="my-style.css" encoding="UTF-8" type="text/css"?>
becomes
<?xml-stylesheet encoding="UTF-8"?>

It seems like it treats the processing instruction xml-stylesheet like xml.
The xml-stylesheet does not have attributes encoding or version, but it has attribute href and type.

Please give the capability to configure teh XML catalog settings of lsp4xml language server with VSCode. Thanks!

Not a blocking issue. Just some annoying warning messages in debug console if I have xml extension installed.

[redhat.vscode-xml] Accessing a resource scoped configuration without providing a resource is not expected. To get the effective value for '[xml]', provide the URI of a resource or 'null' for any resource.
[redhat.vscode-xml] Accessing a window scoped configuration for a resource is not expected. To associate 'xml.completion.autoCloseTags' to a resource, define its scope to 'resource' in configuration contributions in 'package.json'.

The first one:

The second one:

${workspaceRoot}/.mvn/maven.config

--settings .mvn/local-settings.xml

leads to

[xml] Content is not allowed in prolog. [ContentIllegalInProlog]

This is not an XML file as far as I can tell. Trying to point Maven at a mirror using project specific settings. Maven from command line works fine.

I would like to register the same schemas be used for all *.xsd and *.Format.ps1xml files. Is there a way to do that through a setting?

if you save http://java.sun.com/dtd/web-app_2_3.dtd locally and open it in VS Code, an error shows up on the 1st ELEMENT, L72. "The markup in the document preceding the root element must be well-formed."
DTDs are not actual xml documents themselves, so they should not be validated against lsp4xml.

right now, the vscode-xml release process rebuilds the whole lsp4xml package from master, it should instead download the released version, without building it and simply embed it.

Follow https://github.com/redhat-developer/vscode-java/blob/master/CONTRIBUTING.md#sideloading

getSettings should mostly be equivalent to

let configXML = workspace.getConfiguration('xml');
// add missing log file settings
let settings: Settings = {
    configXML
}
return settings;

That makes all xml settings automatically sent to the server, so no need to change anything here when new settings are added to package.json

I have tried to test code action in VSCode but it doesn't work altough with Eclipse LSP4E it works?

Here a sample:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	<bean>
	                      dddddddddddddddddd
	</bean>
</beans>

Code action to remove dddddddddddddddddd is displayed, but when I click on it, it doesn't work?

Have you an idea? i sit a problem from lsp4xml? Thanks for your investigation.

Enable the server to be started with proxy values if they exist.

Existing default vscode preferences already there for proxy information.
Just search proxy in preferences.

I would like to try out this extension. I tried it on this small example project https://raw.githubusercontent.com/microclimate-devops/xml-language-server/master/client-vscode/xml-client/readme-resources/examples.zip from another XML extension, but I cannot get any of the features to work.

How do I debug this? I don't see an output channel for the extension, is there any way to enable logging?

See http://download.jboss.org/jbosstools/vscode-xml/staging/?C=M;O=D: on Oct 11th 2018, the extension went from 5.1MB to 7.0MB (vscode-xml-0.2.0-348.vsix).

Need to investigate what happened there.

I want to write the android layout xml file in vscode, with this plugin and the xsd file from repo,

but there are two xsd files, I don't how to config the association between them, could you please give a sample? (with element type and attribute completion)

if systemId set to the android-layout.xsd, element could be completed but attribute doesn't;
if using the android-attribute.xsd, none of them work.

provide a project description with

• requirements,
• features
• building instructions
• installation instructions (see download area)

I need to validate XML files against their XML schemas, and injecting xsi:schemaLocations into those files is not possible/feasible.

XML catalogs should solve that, yet I can't get that to work.

What I tried in USER SETTINGS:

    "xml.catalogs": [
        "O:\\git\\odata-csdl-schemas\\catalog.xml"
    ]

The file O:\git\odata-csdl-schemas\catalog.xml contains

<?xml version="1.0"?>
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">
  <uri name="urn:oasis:names:tc:entity:xmlns:xml:catalog" uri="jar:file:/C:/eclipse-Photon/plugins/org.eclipse.wst.standard.schemas_1.0.800.v201711201732.jar!/xsd/xmlcatalog11.xsd" />
  <uri name="http://docs.oasis-open.org/odata/ns/edmx" uri="http://localhost/odata-schemas/edmx.xsd" />
  <uri name="http://docs.oasis-open.org/odata/ns/edm" uri="http://localhost/odata-schemas/edm.xsd" />
</catalog>

The first entry is copied from Eclipse's system_catalog.xml and should help validate the catalog.xml - it doesn't.

The second and third entries map the XML namespaces I'm actually interested in to local copies of the corresponding XML Schema files. The files are accessible via my local web server at the URIs listed in the file. Neither validation nor code completion are working as expected.

Removing the first entry with the jar: URL doesn't make the other two work.

What am I doing wrong?

Thanks in advance
Ralf

I have installed vscode-xml-0.3.0-630.vsix and nothing is working (hover, completion, etc). I have checked that in the trace that vscode client sends requests, but there is never response from the lsp4xml server.

I don't know if it's an issue with lsp4xml? It works with Eclipse IDE (LSP4E)

I'm using VSCode:

Version : 1.29.1 (system setup)

I have noticed in https://github.com/gorkem/vscode-xml/blob/master/src/javaServerStarter.ts#L33 that you consume the org.eclipse.lsp4xml-all.jar which contains only https://github.com/angelozerr/lsp4xml/tree/master/org.eclipse.lsp4xml and their dependencies but it doesn't contains extension projects https://github.com/angelozerr/lsp4xml/tree/master/extensions (to have completion, validation for XML Schema, compleetion for Emmet, etc)

I would like to clarify if org.eclipse.lsp4xml-all.jar should exist? In my Eclipse client https://github.com/angelozerr/lsp4e-xml, I'm using all JARs https://github.com/angelozerr/lsp4e-xml/tree/master/org.eclipse.lsp4e.xml/server and I build the Jar command with those files?

@fbricon I believe that you want not to have an org.eclipse.lsp4xml-all.jar , no?

Good day,
I will like to report an issue I noticed.

I created a custom xsd schema for a xml file. Am using Vscode with your vscode-xml extension.

The schema works for only the top elements giving me all its attributes from my xsd file but not on the nested elements in the xml file.

I used the same xsd schema file in Jetbrain Intellij and it worked fine.

Here is an example of my issue.

I will really appreciate it if you could solve this problem in vscode for me. Thanks

And nice work on this project.

When splitAttributes is enabled, elements with one attribute get split onto multiple line. For example:

<myelement key="some_key">hellow</myelement>

becomes

<myelement
          key="some_key">hellow</myelement>

The splitAttributes comment says it will split multiple attributes onto a new line. I'm not sure if this is the expected behavior but it would nice to have elements with one attribute stay on the same line.

// Split multiple attributes each onto a new line
"xml.format.splitAttributes": true,

It seems like something in the way you (or one of your dependencies) use java causes it to over time leak file handles, which in turn makes windows expand the virtual memory page table and eat all available RAM...

Please see these two comments on this issue for more details:

Need to set "xml.useCache":true in the extension preferences. See eclipse/lemminx#159

There is no way to peak inside of collapsed xml node without expanding it again.

I frequently want to space-separate a value in my XSL output and do so by using the following XSL

    <xsl:template match="d:blah">
        <xsl:text> </xsl:text>
        <xsl:element name="{local-name()}">
            <xsl:apply-templates />
        </xsl:element>
    </xsl:template>

But when I format the XSL using your extension, it removes the space from between the xsl:text tags. Please can you add a setting to preserve whitespace?

In other languages, this is rendered in a normal font

When trying to build vscode-xml on Windows 10 Enterprise 1803 I run into a few issues:

3. After manually downloading the maven-wrapper.jar I ran into another maven-related error so I decided to look over at https://github.com/angelozerr/lsp4xml where I found the hint to

• Run ./mvnw clean verify (OSX, Linux) or mvnw.cmd clean verify (Windows)
  Doing that gave me another bunch of errors:

4. Ignoring these errors I headed back to vscode-xml and re-ran npm run build-server which then succeeded.

So apparently just some steps are missing in CONTRIBUTING.md:

• cd ../lsp4xml
• Run ./mvnw clean verify (OSX, Linux) or mvnw.cmd clean verify (Windows)
• cd ../vscode-xml

Plus the advice to ignore certain warnings or errors 😃

Create the configuration in package.json for joinCommentLines (normalize the content) and possibly other preferences for the future.

When I change a dtd <!ELEMENT> declaration the file doesn't validate automatically. I have to force restart VSCode to see, if my changes fixed the problem.

Example:

<?xml version="1.0"?>
<!DOCTYPE student [
  <!ELEMENT student (surname,id)>
  <!ELEMENT surname (#PCDATA)>
]>
<student>
  <surname>Smith</surname>
  <id>567896</id>
</student>

This file is invalid because its missing <!ELEMENT id (#PCDATA)>. Adding the line doesn't cause the error to disappear, only after restarting VSCode the problem is it fixed.
