GPath is a path expression language integrated into Groovy which allows parts of nested structured data to be identified.

In the following sample we want to get the first book’s author’s id. Let’s see the code first: def response = new Xml Slurper().parse Text(books) def book = response.value.books.book[0] (1) def book Author Id1 = [email protected] (2) def book Author Id2 = book['@id'] (3) assert book Author Id1 == '1' (4) assert book Author Id1Integer() == 1 (5) assert book Author Id1 == book Author Id2def response = new Xml Slurper().parse Text(books) // .'*' could be replaced by .children() def catcher In The Rye = response.value.books.'*'assert catcher In The Rye.title.text() == 'Catcher in the Rye' What if we would like to look for a given value without having to know exactly where it is.

Let’s say that the only thing we know is the id of the author "Lewis Carroll" . Using def response = new Xml Slurper().parse Text(books) def node Name = def with Id2or3 = assert ['book', 'author', 'book', 'author'] == response.value.books.depth First()All(with Id2or3).collect(node Name) assert ['book', 'book', 'author', 'author'] == response.value.books.breadth First()All(with Id2or3).collect(node Name)def writer = new String Writer() def xml = new Markup Builder(writer) (1) xml.records() def records = new Xml Slurper().parse Text(String()) (3) assert first()text() == 'HSV Maloo' assert last()text() == 'Royale'def xml Writer = new String Writer() def xml Markup = new Markup Builder(xml Writer) xml Markup.movie(id: 2) def movie = new Xml Slurper().parse Text(xml String()) assert [email protected] == 2 assert text() == 'the godfather'def xml Writer = new String Writer() def xml Markup = new Markup Builder(xml Writer) xml Markup .'x:movies'('xmlns:x': ' def movies = new Xml Slurper() (2) .parse Text(xml String()) .declare Namespace(x: ' assert movies.'x:movie'.last()[email protected] == 2 assert movies.'x:movie'.last().text() == 'ronin'def xml Writer = new String Writer() def xml Markup = new Markup Builder(xml Writer) xml Markup .'x:movies'('xmlns:x': ' def movies = new Xml Slurper() .parse Text(xml String()) .declare Namespace(x: ' assert movies.'x:movie'.size() == 4 assert movies.'x:movie'*.text().every build Movie List = xml Markup.'x:movies'('xmlns:x': ' def movies = new Xml Slurper() .parse Text(xml String()) .declare Namespace(x: ' assert movies.'x:movie'.size() == 4 assert movies.'x:movie'*.text().every """ def builder = parsers.

In this tutorial, we have read and written XML files with Java DOM API.

A DOM parser comes with JDK, so there is no need to download a dependency.

A PI begins with a " is a PI (in this case, a XML instruction) that attaches a XSL style sheet to the XML document for layout processing.
