but to find all process elements that contain XAG in their control
attribute you could do

select="key('control', 'XAG')"

so long as you key was defined something like


<xsl:key match="process" use="@control"/>
<xsl:key match="process" use="substring-before(@control,' ')"/>
<xsl:key match="process" use="substring-after(@control,' ')"/>
<xsl:key match="process" use="substring-before(substring-after(@control,' '),' ')"/>
....

Cheers,
Wendell
