Re: [xsl] Assigning new attribute value

["Mark Wilson mark@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Thanks Michael and Martin. I tried to use the name() earlier, but

will try your methods now.

Whichever attribute is present, I must keep its name but change its value. I have created a brute-force template that I assume will work.
