Dear All:
I would like to evaluate an XPath expression relative to a given element.
I have been reading here: http://www.w3schools.com/xpath/default.asp
And it seems like one of the syntaxes below should work (esp no leading slash or descendant:)
However, none seem to work in HTMLUnit. Any help much appreciated (oh this is a groovy script btw). Thank you!

#!/usr/bin/env groovy
import com.gargoylesoftware.htmlunit.WebClient
def html="""
<html><head><title>Test</title></head>
<body>
<div class='levelone'>
<div class='leveltwo'>
<div class='levelthree' />
</div>
<div class='leveltwo'>
<div class='levelthree' />
<div class='levelthree' />
</div>
</div>
</body>
</html>
"""
def f=new File('/tmp/test.html')
if (f.exists()) {
f.delete()
}
def fos=new FileOutputStream(f)
fos<<html
def webClient=new WebClient()
def page=webClient.getPage('file:///tmp/test.html')
def element=page.getByXPath("//div[@class='levelone']")
assert element.size()==1
element=page.getByXPath("div[@class='levelone']")
assert element.size()==0
element=page.getByXPath("/div[@class='levelone']")
assert element.size()==0
element=page.getByXPath("descendant:div[@class='levelone']") // this
gives namespace error
assert element.size()==0
Thank you!!!
