Hi Monks, I'm trying to print all of the matching XML node info if the value (6444) for one of the attributes is found. I've tried using XML Simple, Twig and even attempted to write my own, all without any success. The furthest I've managed to get is the following. XML file; 

 
<root>
    <ProductKey>99</ProductKey>
    <Test size = "50">
        <Job tags = "boo baa">
           <Volume VolumeCategory="L" MeasurementCategory="Real">0.063
+</Volume>
           <Volume VolumeCategory="cuft" MeasurementCategory="Real">2.
+2</Volume>
           <Volume VolumeCategory="6444" MeasurementCategory="Deal">2.
+2</Volume>
        </Job>
    </Test>
    <Test size = "100">
        <Volume VolumeCategory="L" MeasurementCategory="Real">0.063</V
+olume>
        <Volume VolumeCategory="L" MeasurementCategory="Real">0.063</V
+olume>
        <Volume VolumeCategory="6444" MeasurementCategory="Real">2.2</
+Volume>
    </Test>
    <Test>
        <Volume VolumeCategory="L" MeasurementCategory="Real">0.063</V
+olume>
        <Volume VolumeCategory="L" MeasurementCategory="Real">0.063</V
+olume>
        <Volume VolumeCategory="5555" MeasurementCategory="Real">2.2</
+Volume>
    </Test>
</root>
