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

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...

<?xml version="1.0" encoding="UTF-8"?>

                        xmlns:iso="http://purl.oclc.org/dsdl/schematron";
                        schemaVersion="Test1.0">
        <title>Example</title>

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

Dear All,

I am having an XML file in which I am having the following coding

                               <graphic picfile="I970106058X_bulb"/>

All the graphic filenames are stored in a separate XML file the contents are:

filelist.xml

<files>
<file>./970106058X_c01_0002.tif</file>
<file>./970106058X_c01_0001.tif</file>
<file>./970106058X_bulb.tif</file>
<file>./970106058X_0000.tif</file>
<file>./970106058X_c01_0003.tif</file>
</files>


Now my task is to search the filelist.xml for @picfile value and if it
is not found raise an error.
I am using the following code:

boolean(document('filelist.xml')/files/file[contains(.,
substring-after(concat(@picfile,'.tif'),'I'))] )

But i am not getting any message. Please help me how to achieve this task.

Regards,
Ganesh
