Hi Koorosh,
the compare function belongs to XPath 2 and is not yet supported.
Nevertheless it is possible to define custom functions and to use them
in xpath expressions. This can be done for instance in a (Groovy) script
step. Have a look at the unit test
com.canoo.webtest.steps.verify.VerifyXPathTest#testContext to see an
example in java you can inspire from.
When I've prepared the structure to allow registration of custom
functions, my idea was to provide additional functions (with namespace
wt), among other some from XPath 2... but I haven't needed them until
now and therefore didn't made any progress in this work.

Hi Frank,
I am confused, how can I use verifyProperty to see if one string
lexicographically less or equal to another string. All I can do with
verifyXPath is to use regular expression to do some sort of fuzzy match.
Could you elaborate?
Thanks,
Koorosh

Hi,
As a quick work around you just could replace your verifyXpath task with
verifyProperty
<verifyXPath description="Compare previous against current product"
xpath="compare(#{previousProduct},#{currentProduct}) < 1"
/>
<verifyProperty description="Compare preProd to currentProd"
name="currentProduct"
text="#previousProduct"/>
Cheers,
Frank.
