I need a GPath query to select a node using a numeric index
How do I select from a par开发者_如何转开发sed html document a specific element given its index.
For example: ...
<div>div1</div>
<div>div2</div>
I want to select the second div but it seems to me GPath doesn't offer a solution like Xpath does.
def html = """
<html>
<head>
<title>test</title>
</head>
<body>
<div>div1</div>
<div>div2</div>
</body>
</html>"""
def xml = new XmlSlurper().parseText(html)
assert xml.body.div[0].text() == "div1"
assert xml.body.div[1].text() == "div2"
You can also use collection type methods on the div node such as .each/.find, for example:
xml.body.div.find { it.text() == "div2" }
EDIT:
To clarify my answer a bit, given HTML in the same structure as the sample I listed above but with various content, you can always access the second div using array index 1:
xml.body.div[1]
