Yes, this is what I meant, but apparently there is another issue  
here :-(
When you change the XPath produced by TestGen4Web, it is still run  
through the conversion layer of TestMaker, to make sure it is really  
XPath.

This is done by TestGenForWeb.normalizeXPath(). You can have a look  
at it if you're interested:
    http://cvs.pushtotest.com/cgi-bin/cvsweb.cgi/tm5/TestMaker/src/ 
com/pushtotest/testmaker/XSTest/client/TestGenForWeb.java?annotate=HEAD

The converter doesn't care whether the expression is real XPath or  
pseudo-XPath, and applies its algorithm anyway.
So you can indeed modify the XPath produced by TG4W, but I guess you  
need to make it look like pseudo-XPath.

I hope this will be improved in the future, but if you need to make  
it work right now you should be able to, by following a few rules,  
such as:
   - use "*/" instead of "//" at the beginning of your XPath
   - do not refer to elements without predicates,
     e.g /a/ will be replaced by a single "/", while "/a[1]/" will be  
preserved
   - never use forward slash "/" characters within your predicates

Thus you might have better luck with something like:
       */a[true()]/span[text()="Name" and @class="name"]


Cheers,
