Question

I have one requierment where i want to remove some tags from xml based on condition.

Here is my input xml:

<?xml version="1.0" encoding="UTF-8"?>
<TCXML xmlns="http://www.tcxml.org/Schemas/TCXMLSchema">
<File creation_date="2012-09-20T07:28:47Z" elemId="id280" exportedFileName="sheet 1" last_mod_date="2012-09-20T07:28:48Z" text_flag="8192">

    <GSIdentity elemId="id111" label="R0dB1SzBBT4jNA"/>

</File>
  <File creation_date="2012-09-20T07:18:26Z" elemId="id283"exportedFileName="test part" last_mod_date="2012-09-20T07:18:26Z"  text_flag="8192">

    <GSIdentity elemId="id31" label="SIWBFqLyBT4jNA"/>

</File>
  <File creation_date="2012-09-20T07:21:03Z" elemId="id322" exportedFileName="test part3"  last_mod_date="2012-09-20T07:21:03Z"  text_flag="8192">

    <GSIdentity elemId="id46" label="ycUBFqLyBT4jNA"/>

</File>
  <File creation_date="2012-09-20T07:18:25Z" elemId="id285" exportedFileName="test part2"  last_mod_date="2012-09-20T07:18:25Z"  text_flag="4096">

    <GSIdentity elemId="id29" label="SQRBFqLyBT4jNA"/>

</File>

  <Sheet creation_date="2012-09-20T07:28:48Z" date_released="" ead_paragraph="" elemId="id185"  keep_limit_prop="3" last_mod_date="2012-09-20T07:28:48Z"  object_desc="" object_name="Sheet 1"  ref_list="#id111">

    <GSIdentity elemId="id112" label="R4WB1SzBBT4jNA"/>

</Sheet>


  <PART creation_date="2012-09-20T07:21:22Z" date_released="" ead_paragraph="" elemId="id435"  keep_limit_prop="3" last_mod_date="2012-09-20T07:21:28Z" object_name="dwgTest-AA-dwg1" ref_list="#id29 #id31">

    <GSIdentity elemId="id32" label="SxZBFqLyBT4jNA"/>

</PART>
  <PART creation_date="2012-09-20T07:21:23Z" date_released="2012-09-20T07:21:27Z" ead_paragraph="" elemId="id438"  keep_limit_prop="3" last_mod_date="2012-09-20T07:21:29Z"  object_name="dwgTest-AA-dwg2" ref_list="#id46">

    <GSIdentity elemId="id21" label="itfBFqLyBT4jNA"/>

</PART>
</TCXML>

I want to remove those File tags from this xml which are referred in PART with ref_list tags.

I am trying with following xsl,

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"  xmlns:plm="http://www.tcxml.org/Schemas/TCXMLSchema" version="1.0">
  <xsl:output method="xml" indent="yes"/>

<xsl:template match="@*|node()">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>

<xsl:template match="plm:File">

    <xsl:variable name="Ref_List" select="translate(/plm:TCXML/plm:PART/@ref_list,' ','')" />
    <xsl:variable name="currentElementGSId" select="plm:GSIdentity/@elemId" />  
    <xsl:variable name="RefcurrentElementGSId" select="concat(string('#'),$currentElementGSId)" />  
    <xsl:choose>
        <xsl:when test="((contains($Ref_List,$RefcurrentElementGSId))=true())" >
            </xsl:when>
    <xsl:otherwise>
        <xsl:copy>
            <xsl:apply-templates select="@*|node()" /> 
        </xsl:copy>         
    </xsl:otherwise>
    </xsl:choose>   
</xsl:template>

Above xsl is working only for one PART in the xml and not all PART tags from the xml , how to loop through all PART tags in the xml.
Thanks for your help in advance.

I am looking for output for this xml as follows,

<?xml version="1.0" encoding="UTF-8"?>
<TCXML xmlns="http://www.tcxml.org/Schemas/TCXMLSchema">
<File creation_date="2012-09-20T07:28:47Z" elemId="id280" exportedFileName="sheet 1" last_mod_date="2012-09-20T07:28:48Z" text_flag="8192">

    <GSIdentity elemId="id111" label="R0dB1SzBBT4jNA"/>

</File>

  <Sheet creation_date="2012-09-20T07:28:48Z" date_released="" ead_paragraph="" elemId="id185"  keep_limit_prop="3" last_mod_date="2012-09-20T07:28:48Z"  object_desc="" object_name="Sheet 1"  ref_list="#id111">

    <GSIdentity elemId="id112" label="R4WB1SzBBT4jNA"/>

</Sheet>


  <PART creation_date="2012-09-20T07:21:22Z" date_released="" ead_paragraph="" elemId="id435"  keep_limit_prop="3" last_mod_date="2012-09-20T07:21:28Z" object_name="dwgTest-AA-dwg1" ref_list="#id29 #id31">

    <GSIdentity elemId="id32" label="SxZBFqLyBT4jNA"/>

</PART>
  <PART creation_date="2012-09-20T07:21:23Z" date_released="2012-09-20T07:21:27Z" ead_paragraph="" elemId="id438"  keep_limit_prop="3" last_mod_date="2012-09-20T07:21:29Z"  object_name="dwgTest-AA-dwg2" ref_list="#id46">

    <GSIdentity elemId="id21" label="itfBFqLyBT4jNA"/>

</PART>
</TCXML>

Your input/output do not match your description:

I want to remove those File tags from this xml which are referred in
PART with ref_list tags.

The following XSLT performs an operation equal to that description:

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:plm="http://www.tcxml.org/Schemas/TCXMLSchema" version="1.0">
    <xsl:output method="xml" indent="yes" />
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()" />
        </xsl:copy>
    </xsl:template>
    <xsl:template match="plm:File">
        <xsl:choose>
            <xsl:when test="/plm:TCXML/plm:PART[contains(
                concat(' ', @ref_list, ' '), 
                concat(' #', current()/@elemId, ' '))]">
            </xsl:when>
            <xsl:otherwise>
                <xsl:copy>
                    <xsl:apply-templates select="@*|node()" />
                </xsl:copy>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>
</xsl:stylesheet>

The second template discards any File element whose elemId is found in the ref_list attribute of any PART element. All other File elements are copied as-is.

Note: Your template failed to work as desired because translate expects its first argument to be a string; you passed a node list, which was converted to a string according to the following rule:

A node-set is converted to a string by returning the string-value of
the node in the node-set that is first in document order. If the
node-set is empty, an empty string is returned.
