xmldom xmldom adding xlmns to child nodes when parsing xmls with signatures

Hello, I am using the xmldom through the xml-crypto library and have found a weird behaviour.

When trying to parse an XML with multiple xml signatures, it sometimes automatically adds the "Root's" xlmns to some of the child nodes.

This can be recreated with the following code (Disclaimer: I have simplified the xml for this example):

const { DOMParser } = require("xmldom");

const xml = `<?xml version="1.0" encoding="ISO-8895-1"?>

Needs investigation, with help wanted.

Sorry for the late response.

I created a stackblitz with your sample using the latest version of xmldom (which is published as @xmldom/xmldom since 0.7.0): https://stackblitz.com/edit/js-xmldom-template-f4gqlw?devToolsHeight=33&file=index.js

One minor thing first: The Summary tag in line 4 of your XML sample has not been closed, xmldom automatically closes it. But when you close it the warning that is logged disappears.

The more relevant thing/good news is that the bug you reported, was reported in a different way in #262 and was fixed as part of 0.7.0 / #268.

Luckily xml-crypto has already updated to a version with a fix, so you should already be able to benefit from the fix.
