Can I use variables in XML files?

Is it possible to define variables in an XML file?

For example:

VARIABLE = 'CHIEF_NAME'

 <foods> <food> <name>French Toast</name> <price>$4.50</price> <calories>600</calories> <chief>VARIABLE</chief> </food> <food> <name>Homestyle Breakfast</name> <price>$6.95</price> <calories>950</calories> <chief>VARIABLE</chief> </food> </foods>

You can declare an entity reference for chief and reference it as &chief;:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE foods [ <!ENTITY chief "CHIEF_NAME!"> <!-- .... -->
]>
<foods> <food> <name>French Toast</name> <price>$4.50</price> <calories>600</calories> <chief>&chief;</chief> </food> <food> <name>Homestyle Breakfast</name> <price>$6.95</price> <calories>950</calories> <chief>&chief;</chief> </food>
</foods>

Thats what XSLT is for.

XSLT Wiki

Something to get you started:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="" version="1.0">
<xsl:output method="xml" indent="yes"/>
<xsl:variable name="yourVar" select="'CHIEF_NAME'">
</xsl:variable>
<xsl:template match="/"> <food> <name>French Toast</name> <price>$4.50</price> <calories>600</calories> <chief><xsl:copy-of select="$yourVar" /></chief> </food>
</xsl:template>
</xsl:stylesheet>

This syntax is not exactly correct, but I think generally this is the direction you should seek
