问题
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.
回答1:
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 { it.@tags.text()}.each { div ->
println div.text()
}
This outputs:
test1
test4
