Re: [xsl] Checking external files based on the attribute value

["Darcy Parker" <darcyparker@xxxxxxxxx>]

Hi Ganesh,

There are a few problems with your expression...

The predicate is:
contains(.,substring-after(concat(@picfile,'.tif'),'I'))

Note: There is no @picfile attribute in the
document('filelist.xml')/files/file elements... so
concat(@picfile,'.tif') is going to just return '.tif'.

I don't think you need boolean()

I am assuming your are running the XSL with <graphic
picfile="I970106058X_bulb"/> in your input XML.

I am not sure the context you are calling the expression that checks
for the presence of the slightly modified @picfile value in
filelist.xml... So the following is a guess along with a suggested new
expression:

<xsl:for-each select="//graphic/@picfile"/>
   <xsl:variable name="Currentpicfile" select="."/>
   <xsl:choose>
     <xsl:when test="document('filelist.xml')/files/file[contains(.,substring-after(concat($Currentpicfile,'.tif'),'I'))]">
         Good
     </xsl:when>
     <xsl:otherwise>
         Bad
     </xsl:otherwise>
   </xsl:choose>
</xsl:for-each>

Note:
This type of check is what Schematron is excellent at...

	<let name="RVPStructure"
value="doc(concat($RVPDITABranchHomeURL,'/wbs_precompose/ExpandedRVPStructure.xml'))"/>
									
	<pattern id="GeneralExecutionSteps.Checks">

		<rule context="//graphic/@picfile">
		    <let name="Currentpicfile" value="."/>
		    <assert test="document('filelist.xml')/files/file[contains(.,substring-after(concat($Currentpicfile,'.tif'),'I'))]">Error
@picfile="<value-of select="."/>" does not exist in
filelist.xml</assert>
		</rule>
	</pattern>
</schema>
