Rather than outputting the "<ins>" in the revBegin it would be better to move the above code to a named template and then do the following:

<xsl:choose>
<xsl:when test="is insert">
  <ins>
    <xsl:call-template name="newtemplate"/>
  </ins>
</xsl:when>
<xsl:when test="is delete">
  <del>
    <xsl:call-template name="newtemplate"/>
  </del>
</xsl:when>
</xsl:choose>

So no <xsl:text> nodes, and no need for 'disable-output-escaping'.

Hi,
  I couldnt understand "How can I put
 <ins>
    <xsl:call-template name="newtemplate"/>
  </ins>
instead of only &lt;ins&gt; since my revEnd also outputs &/lt;ins&gt;
If I do like you say what will come there in my revEnd and whats the functionality of "newtemplate". Could you please tell me.

 I have another problem here, after transforming xml, its outputting the whitespaces as &nbsp; to my emulator. How can I escape these whitespaces.

Thanks

You really need to rewrite this code. You are trying to output lexical XML (angle bracket markup) by using disable-output-escaping, and that simply isn't the right way to use XSLT. XSLT is about creating trees first, and serializing them later. When you want to create an element, you should either use a literal result element in the stylesheet, or an xsl:element instruction. The instructions that create the attributes and children of an element in the result tree should be children of the instructions that create that element.

As a result your code structure is all wrong, and your problem with the error message you reported is a symptom of this. Sorry to be brutal, but I would chuck out what you have and start again, with the firm resolution never to use d-o-e.

  Actually this xslt was from one of my colleague, after our discussion I asked him about it. They said that they did it intentionally only since we have a service which applies our xslt rules. I have to discuss with my supervisor and come to you again.
