I have one huge xml file containing results from a PMD run on some source code.

<pmd>
<file name="aaa\bbb\ccc.java">
<violation priority="5"/>
<violation priority="4/>
</file>
<file name="aaa\ddd\eee.java">
<violation priority="4"/>
<violation priority="6"/>
</file>
</pmd>

I would like to filter data by file directory first and then by priority. An example would be to output data on all java files in "aaa\ddd" with a "4" priority.
I also want to keep the root node intact during the transfer, including all of its attribute values.

I have xml to filter by priority already, but the double-filtering I require here is beyond my ability. Any help would be appreciated.

Hey, I eventually figured out a way to do this, so I thought I would post the results here. Instead of trying to get the data that I wanted and telling it to move, I realised that moving all the data, and telling the data I didn't want to STAY was the easiest solution:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
<xsl:output method="xml"/>
<xsl:template match="node() | @*">
<xsl:copy>
<xsl:apply-templates select="node() | @*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="pmd/file[not(contains(@name,'aa\bb'))]" />
<xsl:template match="pmd/file/violation[@priority >'3']"/>

</xsl:stylesheet>

This basically copies all data except that greater than a certain priority or data that does not contain a particular string for a partiular attribute value.
