Question

I am parsing a document using XSLT. Within the XSLT I am loading a reference document using the document() function, and I can access items from both documents. Both the source document and the reference document have an attribute called name. How do I compare one to the other. I have got around this by declaring a variable, but I would rather do it without if possible. In my mind, I need to put namespaces around things, but have no idea how to do it.

source document:

<?xml version='1.0' encoding='UTF-8'?> <SoccerMatch revision='21' id='2849180' date='20080405' scheduledStart='1245' venue='Emirates Stadium' status='Result' comment='' league='Friendly Match' attendance='60111'>     <stuffhere>stuff</stuffhere>     <stuffhere>stuff</stuffhere>     <stuffhere>stuff</stuffhere>     <stuffhere>stuff</stuffhere>     <stuffhere>stuff</stuffhere> </SoccerMatch> 

reference document (comp.xml):

<?xml version='1.0' encoding='utf-8'?> <competitions>     <competition id='100' league='Barclays Premier League'/>     <competition id='101' league='The Coca-Cola Football League Championship'/>     <competition id='101' league='The Coca-Cola Football League Championship Play-Offs Semi-Final'/>     <competition id='101' league='The Coca-Cola Football League Championship Play-Offs Final'/>     <competition id='102' league='Coca-Cola Football League One'/>     <competition id='102' league='Coca-Cola Football League One Play-Offs Semi-Final'/>     <competition id='102' league='Coca-Cola Football League One Play-Offs Final'/>     <competition id='103' league='Coca-Cola Football League Two'/>     <competition id='103' league='Coca-Cola Football League Two Play-Offs Semi-Final'/>     <competition id='103' league='Coca-Cola Football League Two Play-Offs Final'/>     <competition id='104' league='Blue Square Premier'/>     <competition id='104' league='Blue Square Premier Play-Offs Semi-Final'/>     <competition id='104' league='Blue Square Premier Final'/>     <competition id='105' league='Nationwide Championship Shield'/>     <competition id='120' league='Clydesdale Bank Premier League'/>     <competition id='121' league='The Irn-Bru Scottish Football League Championship First Division'/>     <competition id='121' league='The Irn-Bru Scottish Football League Championship First Division Play-Offs Semi-Final'/>     <competition id='121' league='The Irn-Bru Scottish Football League Championship First Division Play-Offs Final'/>     <competition id='122' league='The Irn-Bru Scottish Football League Championship Second Division'/>     <competition id='122' league='The Irn-Bru Scottish Football League Championship Second Division Play-Offs Semi-Final'/>     <competition id='122' league='The Irn-Bru Scottish Football League Championship Second Division Play-Offs Final'/>     <competition id='123' league='The Irn-Bru Scottish Football League Championship Third Division'/> </competitions> 

XSLT

<xsl:template match='/SoccerMatch'> <xmlfeed> <payload payload_class='mobile_football_match_details' payload_name='Payload'> <xsl:variable name='compId' select='document('comp.xml')/competitions/competition[@league=@league]/@id' /> 

Answer 1

Don’t see a ‘name’ attribute in your xml. Do you mean ‘id’? I don’t think you can control namespaces here. See Ken Holman’s discussion on this point here.

I would go with your idea of variables. Something like:

<xsl:template match='/SoccerMatch'>  <xsl:variable name='matchId' select='@id'/>      <xsl:for-each select='document('competitions.xml')/competitions/competition'>    <xsl:if test='$matchId = @id'>      <xmlfeed>       <payload payload_class='mobile_football_match_details' payload_name='Payload'>         <!-- add more stuff here-->       </payload>      </xmlfeed>    </xsl:if>  </xsl:for-each>
