A small package to transverse xml into javascript

Example

import { readFileSync } from "fs";
import parse from "saxxmlparser";

var xml = readFileSync("xml.xml");

parse(xml).then((node) => {
  var price = node.resolveNSPath(
    "A:envelope/A:body/B:getstockPriceResponsE/B:price",
    {
      A: "http://www.w3.org/2001/12/soap-envelope",
      B: "http://www.example.org/stock",
    }
  );
  console.log(price.value); // Prints 34.5
});

xml.xml

<?xml version="1.0"?>
<soap:Envelope
xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">

  <soap:Body xmlns:m="http://www.example.org/stock">
    <m:GetStockPriceResponse>
      <m:Price>34.5</m:Price>
    </m:GetStockPriceResponse>
  </soap:Body>

</soap:Envelope>

Usage

resolving a specific child

import { readFileSync } from "fs";
import parse from "saxxmlparser";

var xml = readFileSync("xml.xml");

parse(xml).then((node) => {
  var price = node.resolveNSPath(
    "A:envelope/A:body/B:getstockPriceResponsE/B:price", // Put the absolute path to the child in here
    {
      A: "http://www.w3.org/2001/12/soap-envelope",
      B: "http://www.example.org/stock",
    }
  );
  console.log(price.value); // Prints 34.5
});

Resolving a child whose parents don't matter

Sometimes when you only want a specific child but the parents or the path does not matter

import { readFileSync } from "fs";
import parse from "saxxmlparser";

var xml = readFileSync("xml.xml");

parse(xml).then((node) => {
  // A double slash (//) in front of the search triggers a child search
  var price = node.resolveNSPath(
    "//B:price", // Put the absolute path to the child in here
    {
      A: "http://www.w3.org/2001/12/soap-envelope",
      B: "http://www.example.org/stock",
    }
  );
  console.log(price.value); // Prints 34.5
});

Resolving a child of a child whose parents don't matter
