hello

I would like to check if a specific attribute name class exist in the text, and if so print its value, other wise print different value.
meaning, test on the xml if there is class=program exist. if there is, print its value, if there isnt such a class=program exist in the xml print 'nnnnnnn'

this is my xml

<entity eid="B" tid="511" plural-tid="512" grouping-tid="513" plural-grouping-tid="514" length="256">
  <data class="user-defined" type="varchar" dbcolumn="HANDLER_TYPE" mandatory="no" last-summary="all" collection-id="handler-type" />
  </entity>
<entity eid="C" tid="521" plural-tid="522" grouping-tid="523" plural-grouping-tid="524" length="256">
  <data class="user-defined" type="varchar" dbcolumn="CLASS_NAME" mandatory="no" last-summary="all" collection-id="class-name" />
  </entity>
<entity eid="D" tid="531" plural-tid="532" grouping-tid="533" plural-grouping-tid="534" length="256">
  <data class="user-defined" type="varchar" dbcolumn="COMMAND_LINE" mandatory="no" last-summary="all" collection-id="command-line" />
</entity>

thanks

Sorry, I don't understand your question. In your sample data, all elements seem to have the same attributes (or attributes with the same names but different values). Perhaps you could explain what output you want from this data.

sorry my mystake.
what I meant is to check if there is class name "program".
if there is class="program" print YYY if there is no such class with value "program" pring NNN.

Assuming you don't care what element the attribute appears on, use

<xsl:when test="//@class='program'">YYY</xsl:when>
<xsl:otherwise>NNN</xsl:otherwise>

this is an example of input that should pring 'NNNNN' becuase there is no class='program'.
again, I want to know how can I test if there is class="program' in the input file?
