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.
Error rendering macro 'code' : Invalid value specified for parameter lang
