What is an alternative to this XPath //div[@id='foo'] in GPath? In general, where I can find this documentation?
回答1:
Here is the corresponding snippet:
def node = new XmlSlurper().parseText(...)
def foo = node.depthFirst().findAll { it.name() == 'div' && it.@id == 'foo'}
A few other links you may want to read:
- GPath documentation
- Processing XML with Groovy
回答2:
The previous poster gave you all that's required: Assuming your document has been slurped into xml, you want
def foo = xml.path.to.div.find{it.@id == 'foo'}
to find a single result. Or findAll to find all results.
回答3:
To mimic the expression //div[@id='foo'] the closest thing you can do with a GPath is:
def xml = new XmlParser().parseText(text)
xml.'**'.div.findAll { it.@id=="foo" }
the '**' is pretty much the same as '//' in your XPath.
xml.'**'.div
will yield all the nodes of type div at any level.
Later filtering with findAll() with the given closure you get a list of nodes as you do in the XPath case
回答4:
what you need is this:
def root = new XmlSlurper().parseText(<locOfXmlFileYouAreParsing>.toURL().text)
def foundNode = root.'**'.find{ it.@id == "foo" }
its the double * that will let you find it without knowing the path. At least this is how I do it.
