XpathResultMatchers to support Hamcrest Matcher<NodeList> [SPR-17529]

[spring-projects-issues]

Pat Turner opened SPR-17529 and commented

While org.springframework.test.web.servlet.result.XpathResultMatchers supports Hamcrest matcher against a single org.w3c.dom.Node, it doesn't allow matching against multiple nodes via the org.w3c.dom.NodeList.

 

Suggest addition of a new ResultMatcher method in XpathResultMatchers and supporting XpathExpectationsHelper:

public ResultMatcher nodeList(final Matcher<? super NodeList> matcher)

 

My motivation for this is to allow checking that XHTML element IDs are unique across the document, and to do this, I need to match all elements with an ID.

E.g. 

//*[@id]

 

Happy to contribute if you think this is worthwhile adding to framework.
