The code line below works correctly using an XSLT v1.0 engine but gives the following error when using an v2.0 engine...

    "XPTY0004: A sequence of more than one item is not allowed as the first argument of translate()
Transformation failed: Run-time errors were reported"

...
<xsl:variable name="tokenmoid" select="translate(mv/moid,'=',',')"/>
...

I have had a look on the W3C website and cannot find any references to a change in the translate functionality in v2.0. Has anyone else experienced this ??

Cheers

For any function that expects a string as an argument, if you supply a node-set containing more than one node, then:

* XSLT 1.0 will select the string-value of the first node in the node-set

* XSLT 2.0 will report an error.

If you want the 1.0 behaviour, change

translate(mv/moid,'=',',')

to

translate((mv/moid)[1],'=',',')

The reason for changing it is that this is often a latent bug - people don't realise that they are only processing the first node.

This now works although I have no idea what a "latent bug" is ? Probably the same as "user error" :)
Thanks for solving this.

By latent bug I mean a bug that's been in your code for a long time but which you haven't discovered yet, typically because you haven't tested on a wide-enough range of possible input.

It's a significant problem with XSLT because people often put stylesheets into production with minimal testing.
