Hi,

Another alternative to Abel's and Tony's suggestions is to configure
the XSLT to ignore the text nodes you know to be insignificant. This
can be done by having it to discard such nodes before processing the
document.

In the case of this input, you can do something like this:

<xsl:strip-space elements="*"/>

<xsl:preserve-space elements="gnm:Cell"/>

The strip-space will strip whitespace-only nodes in the document
except directly inside gnm:Cell, where it is overridden by the
preserve-space instruction.

This is safe to do because (as long as) you know from your spec of the
input that there will never be any text outside cells ... so all text,
in a valid document, will be whitespace-only, and can be stripped from
the stylesheet input.

Note: I use Abel's namespace prefix since you are going to need that namespace.

Cheers, Wendell
