GPath is a path expression language we've integrated into Groovy which is similar in aims and scope as XPath is to XML.
1. Expression language for tree structured data
2. Implementations for XML
3. Can specify a path to an element
a.b.c -> all the <c> elements inside <b> inside <a>
4. Can specify attributes
a"@href" -> the href attribute of all the a elements
The best example of GPath for xml is test-new/groovy/util/XmlSlurperTest.groovy.
1.Accessing elements as property directly
3.Accessing element body
If the element is a father node,it will print all children's text.
3.Explore the DOM use children() and parent()
but the parent() is not implement in current version XmlSlurper.java, i had upload patch about this.
