Using XPath, is it possible for me to select a whole branch by
searching for the first child to contain some specific text.

For example for the following XML:

<List>
    <Contact>
        <Name>test1test</Test>
        <Data>sample data</Data>
        <Data>sample</Data>
        <Data>sample 123</Data>
    </Contact>
    <Contact>
        <Name>test133</Test>
        <Data>sample data</Data>
    </Contact>
    <Contact>
        <Name>test2test</Test>
        <Data>sample data</Data>
        <Data>sample</Data>
        <Data>sample 123</Data>
    </Contact>
</List>

If I search for "test1" I want from the Xpath to return the first
<Contact> and the second <Contact>, including all child nodes (<Name>
and <Data>):

    <Contact>
        <Name>test1test</Test>
        <Data>sample data</Data>
        <Data>sample</Data>
        <Data>sample 123</Data>
    </Contact>
    <Contact>
        <Name>test133</Test>
        <Data>sample data</Data>
    </Contact>

Something like:
//Name[contains(.,'Ab')]
But this returns only the Name node, and not all the childs.

Thanks,

Andy.
