    Assuming well-formed XHTML, slurp the xml, collect up all the tags, find the 'a' tags, and print out the href and text.

    input = """<html><body>
<a href = "http://www.hjsoft.com/">John</a>
<a href = "http://www.google.com/">Google</a>
<a href = "http://www.stackoverflow.com/">StackOverflow</a>
</body></html>"""

doc = new XmlSlurper().parseText(input)
doc.depthFirst().collect { it }.findAll { it.name() == "a" }.each {
    println "${it.text()}, ${it.@href.text()}"
}
