Russ, ><xsl:choose> ><xsl:when test="((//CUSTOM/F128[. = '1']) $and$ (//CUSTOM/F129[. $ne$ >'1']))"> [snip] > >but I get 'Unspecified error..' - useful!? The fact that you're using $and$ and $ne$ implies that you are using an old version of the MSXML processor, or that you were using an old version and have changed to a new one without updating your code. See the Unofficial MSXML FAQ at http://www.netcrucible.com/xslt/msxml-faq.html. Hopefully that will clear up your unspecified error. '$and$' should be changed to 'and' and '$ne$' should be changed to '!=', giving the test expression: ((//CUSTOM/F128[. = '1']) and (//CUSTOM/F129[. != '1'])) However, you should also be aware of what you're actually testing for here. You are asking the question "is it the case that there is a F128 element whose value is equal to '1' under a CUSTOM element anywhere in the source, and a F129 element whose value is not equal to '1' under a CUSTOM element anywhere in the source?" I think that what you're actually interested in is checking the value of the elements that you know exist rather than finding out whether any elements exist with those particular values. In other words, you want to ask the question "is it the case that the F128 element under the CUSTOM element anywhere in the source has a value equal to '1' and that the F129 element under the CUSTOM element anywhere in the source has a value not equal to '1'? This gives the expression: (//CUSTOM/F128 = '1') and (//CUSTOM/F129 != '1') [you don't actually need the brackets, but you seemed fond of them ;)] The XPaths you're using are obviously examples, but just to point out that both tests rely on there being only a single F128 and a single F129 element underneath a CUSTOM element anywhere in the document.
