parser does not seem to parse some parts of the XML correctly.

[vaikas]

I'm using github.com/2000Slash/gopom to parse the original pom.xml file. It seems to not parse some sections of the XML correctly though, even when just round-tripping an XML file with no patches, there are differences, so I need to dig into it. Maybe some of these are marshaling issues, but some for sure are losing information on the parsing. Here's some things I'm seeing diffs in:

Original:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Marshalled:

<project xmlns="http://maven.apache.org/POM/4.0.0" xsi="http://www.w3.org/2001/XMLSchema-instance" schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

This is for sure being dropped on the parsing (as debugged by looking at the actual structs returned):

The second part has been fixed here:
