 Consider the following input XML file: <?xml version="1.0" encoding="UTF-8"?>
<batch name="level1">
<command src="1" />
<command src="2" failed="true()" />
<command src="3" />
<command src="4" failed="true()" />
<batch name="level2">
<command src="10" />
<command src="11" failed="true()" />
<command src="12" />
<batch name="level3">
<command src="20" />
<command src="21" failed="true()" />
<command src="22" />
</batch>
<command src="30" />
<command src="31" failed="true()" />
<command src="32" />
</batch>
</batch>I need an XSL transformation that scans the top-level batch until it finds a command marked as failed, no matter at which internal batch-level it is, preserving the batch level on the report. Currently, I have this XSL: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan="http://xml.apache.org/xalan"> <xsl:output method="xml" indent="yes" encoding="UTF-8"
media-type="text/xml" xalan:indent-amount="2" /><xsl:strip-space elements="*" /> <xsl:template match="/">
<xsl:apply-templates />
</xsl:template> <!--
FIXME: batches are matched even though there is a prior failed
command or batch containing a failed command
-->
<xsl:template match="batch">
<batch name="{@name}">
<xsl:apply-templates />
</batch>
</xsl:template> <!-- match only the first failing command -->
<xsl:template match="command[@failed=true()][1]">
<failed-command src="{@src}" />
</xsl:template>
</xsl:stylesheet>which generates: <?xml version="1.0" encoding="UTF-8"?>
<batch xmlns:xalan="http://xml.apache.org/xalan" name="level1">
<failed-command src="2" />
<batch name="level2">
<failed-command src="11" />
<batch name="level3">
<failed-command src="21" />
</batch>
</batch>
</batch>instead of: <?xml version="1.0" encoding="UTF-8"?> <batch xmlns:xalan="http://xml.apache.org/xalan" name="level1"> <failed-command src="2" /> </batch> Another example -- if only command[@src='21'] is marked failed, then the generated output should be: <?xml version="1.0" encoding="UTF-8"?>
<batch name="level1">
<batch name="level2">
<batch name="level3">
<failed-command src="21" />
</batch>
</batch>
</batch>Thanks for your help, Adrian.
