Help: How to make XSL think non-existing elem is '' in test

[hepic]

Hi,

In the following xsl,

<xsl:choose>
<xsl:when test=&quot;page[readOnly='']&quot;>
<!-- turn the page to edit mode -->
</xsl:when>

<xsltherwise>
<!-- turn the page to read only -->
</xsltherwise>
</xsl:choose>

The problem is that sometimes element readOnly doesn't exist. In that case, I would like the page to be in edit mode, but it actually turns into read-only. It looks like the the test condition fails if element readOnly doesn't exist. Is there a way we can make XSL evaluate non-existing element to an empty string?

I know I can re-write the condition; however, we have many XSL conditions written in this way, and I wouldn't like to mannually change every one of them if possible.

Thanks a lot for your help!

This should work

<xsl:choose>
<xsl:when test=&quot;page[readOnly='']&quot;>
<!-- turn the page to edit mode -->
</xsl:when>
<xsltherwise>
<xsl:choose>
<xsl:when test=&quot;page[readOnly]&quot;>
<!-- turn the page to read only -->
</xsl:when>
<xsltherwise>
<!-- turn the page to edit mode -->
</xsltherwise>
</xsl:choose>
</xsltherwise>
</xsl:choose>
