xpath

Just an XPath implementation. Should be fairly complete, but there hasn't been further development recently.

Example

ts.xml

xml

<?xml version="1.0" ?><!DOCTYPE TS><TS language="es_ES" version="2.1">
<context>
    <name>AboutDialog</name>
    <message>
        <location filename="../src/lib/other/aboutdialog.ui" line="60"/>
        <source>Authors</source>
        <translation>Autores</translation>
    </message>
    <message>
        <location filename="../src/lib/other/aboutdialog.cpp" line="56"/>
        <source>Authors and Contributors</source>
        <translation>Autores y contribuidores</translation>
    </message>
</context>
</TS>
