Thanks for all the responses and information given.

Atleast now I know where the problem really lies.

Sorry for being presumptuous about the error message not being informative. My mistake. Apologies.

Thanks again to all

Saxon 6.5.3 is an XSLT 1.0 processor.

has an XSLT2.0 processor as Ive used tags such as :
<SubConcept id="{@id}" name="{@name}">
which I believe are version 2.0 compatible.

They are also version 1.0 compatible.

The error message I get is not very informative but Ive pasted it below anyways:

People posting questions so often make this mistake. The fact that you don't understand an error message doesn't mean that no-one else does!

This error message makes it pretty clear that the XPath parser has tried to
interpret if() as a function call, which means it isn't aware of the XPath
2.0 if() then else syntax.

Subject: [xsl] if then else


I wanted to use the 'if then else' clause inside the <xsl:value-of select="">. I tried doing it this way but its obviously wrong as it returns an error.

<Value type="TEXT" ref="{CONCEPT/@ref}">
<xsl:value-of select="if(OBJECT-SLOT) then

OBJECT-SLOT/@name else


What would be the right way of writing it or is it incorrect to have it inside the select attribute of the xsl:value-of tag?

Appreciate any comments or suggestions
