Given a HTML file with the structure html -> body -> a bunch of divs what is the correct groovy statement to find all of the divs with a non blank tags attribute?
The following is not working:
def nodes = html.body.div.findAll { it.@tags != null }
because it finds all the nodes.

Groovy's internal XmlParser and XmlSlurper provide access to XML documents in a Groovy-friendly way that supports GPath expressions for working on the document. XmlParser provides an in-memory representation for in-place manipulation of nodes, whereas XmlSlurper is able to work in a more streamlike fashion.
@Deprecated public class XmlSlurper extends DefaultHandler. Parse XML into a document tree that may be traversed similar to XPath expressions. For example: def rootNode = new XmlSlurper().parseText( '<root><one a1="uno!"/>< two>Some text!</
Try the following (Groovy 1.5.6):
def doc = """
<html>
<body>
<div tags="1">test1</div>
<div>test2</div>
<div tags="">test3</div>
<div tags="4">test4</div>
</body>
</html>
"""
def html = new XmlSlurper().parseText( doc)
html.body.div.findAll { [email protected]()}.each { div ->
println div.text()
}
This outputs:
test1
test4
