Strippin an element in xml and replacing the value of an element based on certain condition using xslt -

i getting stuck @ point need remove element input xml:

<message      xmlns="http://www.origoservices.com"      xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" > <m_control>     <control_timestamp>2013-06-06t14:55:37</control_timestamp>     <initiator_id>asl</initiator_id> </m_control> <m_content>     <b_control>         <quote_type>single company</quote_type>         <quote_or_print>quote , print</quote_or_print>         <generic_quote_ind>yes</generic_quote_ind>         <tpsdata>             <tps_quote_type>comparison</tps_quote_type>         </tpsdata>     </b_control>     <application>      <product>         <tpsdata>             <service_type>quickquote</service_type>             <quote_type>standard</quote_type>         </tpsdata>       </product>     </application> </m_content> </message> 

if <tps_quote_type> 'comparison' change value of <quote_type> 'comparison' , <tpsdata> field should removed. output should below.

<message      xmlns="http://www.origoservices.com"      xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" > <m_control>      <control_timestamp>2013-06-06t14:55:37</control_timestamp>      <initiator_id>asl</initiator_id> </m_control> <m_content>     <b_control>          <quote_type>comparison</quote_type>          <quote_or_print>quote , print</quote_or_print>          <generic_quote_ind>yes</generic_quote_ind>     </b_control>    <application>        <product>           <tpsdata>             <service_type>quickquote</service_type>             <quote_type>standard</quote_type>           </tpsdata>     </product>     </application> </m_content> </message>

maybe noticed handling of elements namespace little painful. add http://www.origoservices.com namespace xslt , pain goes away.

<xsl:stylesheet      version="1.0"      xmlns:xsl="http://www.w3.org/1999/xsl/transform"     xmlns:o="http://www.origoservices.com"      xmlns:dp="http://www.datapower.com/extensions"     xmlns:fn="http://www.w3.org/2005/xpath-functions"     xmlns:date="http://exslt.org/dates-and-times"      extension-element-prefixes="dp"     exclude-result-prefixes="fn date" >     <xsl:output method="xml" indent="yes"/>      <xsl:template match="node() | @*">         <xsl:copy>             <xsl:apply-templates select="node() | @*"/>         </xsl:copy>     </xsl:template>      <xsl:template match="o:b_control/o:quote_type[../o:tpsdata/o:tps_quote_type = 'comparison']">         <xsl:copy>             <xsl:apply-templates select="@*" />             <xsl:text>comparison</xsl:text>         </xsl:copy>     </xsl:template>      <xsl:template match="o:tpsdata[o:tps_quote_type = 'comparison']" />  </xsl:stylesheet> 

notes

• most of "plumbing" not necessary.
• template match expressions don't need full path.
• use match expressions rather <xsl:choose> pinpoint elements want change.
• start basic identity template, overriding needed more specific templates. makes live easier starting modified identity template.
• use empty templates remove specific elements.
