The best way is to merge all your xslt into one, and after that using an xslt.

Thanks for such a quick reply. Really appreciate your help. But the
syntax which you are suggesting is of XSLT-2.0 but I am using XSLT-1.0
so for me "collection" and "for" statement says - "Invalid XPath".
Can you suggest something which goes with XSLT-1.0. I am doing all these
things in Eclipse Editor with the help of plugin provided for xml.

Thanks,
BR,
Varun

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

Hi,

                     I have few xml files (depends on user how much
        he/she wants
                     to pass). I
                     have to take those files and merge them, so I have
        created a
                     loop and in
                     that I am passing these files one by one. For this
        I have
                     written few
                     rules to merge. But there is this <Procedure> tag
        where I am
                     stuck. To
                     merge this I need to parse each Procedure and have
        to modify its
                     attributes (attrProc and attrLevel). I have to
        replace the
                     attrProc
                     attribute with a sequential value and for me this
        will set a
                     unique
                     "Level" for each Procedure tag and later I will
        process them
                     based on
                     their level.

                     I am thinking of looping it and will count the
        occurrences
                     of it and
                     then I am thinking to replace the value. But I am
        not able
                     to do that.
                     Can anyone tell me how to achieve this. How can I
        loop every
                     Procedure
                     tag and and append the attrProc attribute value in a
                     sequential order?


How do you load the files?


I would simply use Saxon 9 and collection, as in

                 <xsl:template match="/" name="main">
                    <InfoTag>
                      <xsl:apply-templates
                 select="collection('.?select=*____.xml')//Procedure"/>

                    </InfoTag>
                 </xsl:template>

                 <xsl:template match="Procedure">
                    <Procedure attrProc="{position()}" attrLevel="###
        NOT UNIQUE
                 ###">
                      <xsl:apply-templates/>
                    </Procedure>
                 </xsl:template>

                 maybe with an additional <xsl:sort
        select="@attrLevel"/> on the
                 apply-templates of the collection, depending on which
        ordering
                 you need. If the name of the files are known then you
        can of
                 course also do

                 <xsl:template match="/" name="main">
                    <InfoTag>
                      <xsl:apply-templates select="for $file in
                 (doc('file1.xml'), doc('file2.xml')) return
        $file//Procedure"/>
                    </InfoTag>
                 </xsl:template>

                 <xsl:template match="Procedure">
                    <Procedure attrProc="{position()}" attrLevel="###
        NOT UNIQUE
                 ###">
                      <xsl:apply-templates/>
                    </Procedure>
                 </xsl:template>
