ut-function.xml2json - practical XML parsing

Use precompiled template to extract meaningful object from XML junk

Usage

<!-- template.xml -->
<some>
    <deep>
        <nested>
            <structure>${a}</structure>
        </nested>
    </deep>
    <veryVeryLongTagName>${b.c}</veryVeryLongTagName>
    <potentially>
        <missing>${d}</missing>
    </potentially>
<some>

<!-- payload.xml -->
<randomNameSpace:some xmlns:randomNameSpace="http://randomNameSpace.com">
    <deep>
        <nested>
            <structure>value 1</structure>
        </nested>
    </deep>
    <veryVeryLongTagName>value 2</veryVeryLongTagName>
    <something>
        <weDoNotCareAbout>value 3</weDoNotCareAbout>
    </something>
</randomNameSpace:some>
