I am using xpath within a BizTalk 2006 orchestration.
I get the following error "Expression must evaluate to a node-set".
My xml:
<EmailListResponse xmlns="http://BTTest">
<PersonContact EMailContactValue="te***@mail.com" />
<PersonContact EMailContactValue="te***@mail.com" />
</EmailListResponse>
My xpath expression which generates the error message:
varNoOfEmailAddresses = (System.Int32)xpath(msgEmailListRes, "count(/
*[local-name()='EmailListResponse']/*[local-name()='PersonContact']/
*[[local-name()='EMailContactValue']
[not(text()=preceding::EMailContactValue/text())])");
varNoOfEmailAddresses is a local orchestration variable
msgEmailListRes is a local orchestration message
Kan anyone tell me what I am doing wrong?
I have the following xml and xpath expression, which does not fail
(very similar):

varNoOfCountries = (System.Int32)xpath(msgSHT_Req, "count(/*[local-
name()='SHT_Req']/*[local-name()='Body']/*[local-
name()='NotifyCountries']/*[local-name()='CountryCode']
[not(text()=preceding::CountryCode/text())])");
varNoOfCountries is a local orchestration variable
msgSHT_Req is a local orchestration message
