Recangles with ItemTransform="0 -1 1 0 -10270.29114161777 -472.53182401247494" for example, as reported in https://redmine.le-tex.de/issues/15526

This support should be feasible since we can now use XPath 3.1 trigonometric functions. We will require XSLT 3 support (available in https://github.com/transpect/calabash-frontend/tree/saxon98, its mirror https://subversion.le-tex.de/common/github-mirror/calabash_saxon_9.8/ or in more recent branches like https://github.com/transpect/calabash-frontend/tree/saxon10 or https://subversion.le-tex.de/common/github-mirror/calabash_saxon_10/) anyway because of an impending re-implementation of nested style handling that uses xsl:accumulator.

Hi Gerrit,
attached are two idml test cases and the two corresponding hub.xml (conversion made with the latest git pull).
In the file test_no_mml.hub.xml everything is ok.
In the file test_with_mml.hub.xml the content of the para before the table is missing.

It seems that the issue arise only when you have mml and a Content and a Table in the same CharacterStyleRange, but not always, as I have files where only some paras gets dropped.

I have solved the problem by editing the source indd and making sure all tables are in their CharacterStyleRange with no other Content elements, but I think this should be investigated further.

When the src idml has dup style names (eg a para style and a char style)
idml2xml/xsl/modes/GenerateHubformat.xsl
fails with the following error at line 792:
A sequence of more than one item is not allowed as the value of variable $lang-by-style (@xml:lang, @xml:lang)

When exporting to idml with mathtools v3 and the mathml string goes in a MathToolsML attribute, not in an element as implied by the <p:viewport match="MathToolsML"> in idml2hub.xpl.

To get the hub.xml I have to move the MathToolsML attribute as an element under CharacterStyleRange/Properties, but then there are paragraph splitting issues in SeparateParagraphs.xsl.

Attached is a simple idml test case exported from mathtools

v3.

Hello,
when converting the attached idml the sidebar content get lost and only anchors are present:

The content is ok in output from previous step in idml2xml.HUB.07a.idml2xml_XML-Hubformat-properties2atts.xml

I think the problem is in mode idml2xml:XML-Hubformat-extract-frames templates in GenerateHubformat.xsl

Tested with latest 2beb2b8..b6ce1ad
Attaches the idml test doc and the generated hub.

Thanks

Hi,
I have encountered an edge case when converting from mathtools to mml (see attached idml).

Mathtool sometimes (I do not understand when|why) emit an empty @MathToolsML on a charrange containing text content and this content get lost due to the <p:delete name="remove-MathTools-Markup"... line in idml2hub.xpl.

Solution is to modyfy above line from
<p:delete name="remove-MathTools-Markup" match="*[@MTMathZone][not(descendant::mml:math or descendant::Rectangle)] |CharacterStyleRange[descendant::mml:math]/Content[not(normalize-space())]"/>
to
<p:delete name="remove-MathTools-Markup" match="*[@MTMathZone][not(descendant::mml:math or descendant::Rectangle)][not(MathToolsML='')] |CharacterStyleRange[descendant::mml:math]/Content[not(normalize-space())]"/>

I think this should be pretty safe and (hopefully) should not introduce any regression.
