RE: Removing dead targets from Ant build files

Hi Graham and all other xsl-list contributors,

To only remove targets not listed in depends attributes (or project
default attribute),
it looks something like this (xsl 1.0):

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	exclude-result-prefixes="xsl">
<xsl:output method="xml" indent="yes" encoding="utf-8"/>
<xsl:template match="/project">
  <xsl:copy>
    <xsl:apply-templates/>
  </xsl:copy>
</xsl:template>
<xsl:template match="target">
  <xsl:variable name="name" select="@name"/>
  <xsl:if test="//target[contains(@depends,$name)] or
/project[@default=$name]">
    <xsl:copy-of select="."/>
  </xsl:if>
</xsl:template>
</xsl:stylesheet>

I tested it with some very simple ant build files, using the msxsl
processor.
This will remove any target that is not listed in either
/project/@default or any //target/@depends.
IIRC ant complains if some target/@depends contains a non existing
target,
so I didn't bother cleaning up the target/@depends.

Breaking up large build files into smaller ones is something completely
different.
I would do that in XSLT 2.0 anyway using xsl:result-document.

Regards,
Peter
