Parsing the XML an returning the root node as a Node
Checking we’re
using a Node
Traversing the tree in a GPath style
Let’s see the similarities between
XMLParser
and
XMLSlurper
first:
Both are based on
SAX
so they both are low memory footprint
Both can update/transform the XML
But they have key differences:
XmlSlurper
evaluates the structure lazily. So if you
update the xml you’ll have to
evaluate the whole tree again.
XmlSlurper
returns
GPathResult
instances when parsing XML
XmlParser
returns
Node
objects when parsing XML
When to use one or the another?
If you want to transform an existing document to another then
XmlSlurper
will be
the choice
