Testing for the presence of a node

[Anonymous]

Hello All,
I am writing an XSL and want to know how can I check an XML document for a presence of a particular node. Let me give you an example...

  
<Result>
        <True/>
</Result>

In my XSL I want to check if the node true is there or the node false is there.
Any help will be appreciated.
Thanks in Advance!!

Well, I guess the question is whether there will always be either a true or false node. If so, and assuming that the <Result> node is the context node you could do something like this:

  
<xsl:choose>
  <xsl:when test="self::node()[True]">
    do what you're going to do if true is there
  </xsl:when>
  <xsl:otherwise>
    do what you're going to do if false is there
  </xsl:otherwise>
<xsl:choose>

If it is not always guaranteed that a true or false node is always there you can change the otherwise to a when. Also if you want to do this check from a node other than the Result node then the axis and node test (self::node()) will need to be changed.
Hope this helps.
