Also, FWIW, in trying to use web_reg_save_param_xpath I can't even extract a single parameter based on XPath!
When I test the code code ...
web_reg_save_param_xpath("ParamName=Correlation1","QueryString=//a[1]/@href", SEARCH_FILTERS,"Scope=Body", LAST);
...it should extract the href of the first <a> tag on the page, but it doesn't. The code:
web_reg_save_param_xpath("ParamName=Correlation1","QueryString=//a[contains(.,'Foo')]/@href", SEARCH_FILTERS,"Scope=Body", LAST);
...should extract the href of the 'Foo' link from above, but again it doesn't.
What am I doing wrong?
