Validating xml writer
Specifications for XML and XML schemas include multiple security flaws.
At the same time, these specifications provide the tools required to protect XML applications.
Marshal handles all other data by writing one or more XML elements containing the data.
The name for the XML elements is taken from, in order of preference: - the tag on the XMLName field, if the data is a struct - the value of the XMLName field of type Name - the tag of the struct field used to obtain the data - the name of the struct field used to obtain the data - the name of the marshaled type - the XMLName field, described above, is omitted. - a field with tag "name,attr" becomes an attribute with the given name in the XML element.

The two main places where you use GPath expressions is when dealing with nested POJOs or when dealing with XML Next step is to get the some values from a given node’s attribute.
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 (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.
Marshal handles a pointer by marshaling the value it points at or, if the pointer is nil, by writing nothing.
Marshal handles an interface value by marshaling the value it contains or, if the interface value is nil, by writing nothing.
