Re: [xsl] Replacing the element's attribute in sequential order

["varun bhatnagar varun292006@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi,

Thanks a ton for the reply.
I am using XSLT-1.0 so I don't think for loop will work. I am loading the
file using python code, lxml library does that for me. I pass my files one
by one to the method given below and merge the files.

 def startXSLTMerge(self, mergeFileName, inputFile):
        parser = etree.XMLParser()
        parser.resolvers.add(FileResolver())

        xml_input = etree.parse(open(inputFile,'r'), parser)
        xslt_root = etree.parse(open(mergeGeneric.xsl','r'), parser)
        transform = etree.XSLT(xslt_root)
        result = str(transform(xml_input))
        print str(transform(xml_input))

        f = open('Merged_File.xml', 'w+')
        f.write(str(result))
        f.close()

I was trying something like this (this is not giving me the correct result,
but something which I have tried):

<xsl:template match="/InfoTag/Procedure">
<xsl:variable name="countDocProcedures">
<xsl:value-of select="count(/InfoTag/Procedure)"/>
</xsl:variable>
 <xsl:variable name="countProcedures">
<xsl:value-of select="count(document('NewFile1.xml')/InfoTag/Procedure)"/>
</xsl:variable>

<xsl:variable name="totalProcedures">
<xsl:value-of select="$countDocProcedures + $countProcedures"/>
</xsl:variable>
 <xsl:call-template name="callProcedure">
<xsl:with-param name="test" select="$totalProcedures"/>
</xsl:call-template>
</xsl:template>
 <xsl:template name="callProcedure">
<xsl:param name="test"/>
 <xsl:if test="$test &gt; 0">
<xsl:copy>
<xsl:if test="/InfoTag/Procedure/downTime">
<xsl:attribute name="attrProc">
<xsl:value-of select="$test"></xsl:value-of>
</xsl:attribute>
<xsl:attribute name="attrLevel">
<xsl:value-of select="'##### NOT UNIQUE#####'"></xsl:value-of>
</xsl:attribute>
<xsl:copy-of select="downTime"></xsl:copy-of>
</xsl:if>
</xsl:copy>
<xsl:call-template name="callProcedure">
        <xsl:with-param name="test" select="$test - 1"/>
      </xsl:call-template>
</xsl:if>
</xsl:template>

It is getting '10' in test parameter which I have passed. Still trying to
find out why.
Could you help me.


Thanks,
BR,
Varun
