Form html updating xml
A bit ironically, no error is generated for meaningless but non ambiguous conflicts, for example both renaming and deleting the same node (The XQuery Update Facility is a powerful, convenient and elegant extension of the XQuery language, in spite of a few peculiarities that can be slightly off-putting for programmers.
We are looking forward to its wide adoption as the language of choice for updating XML databases.

The W3C HTML Working Group is the W3C working group responsible for this specification's progress.
The form author can validate user data against XML Schema data types, require certain data, disable input controls or change sections of the form depending on circumstances, enforce particular relationships between data, input variable length arrays of data, output calculated values derived from form data, prefill entries using an XML document, respond to actions in real time (versus at submission time), and modify the style of each control depending on the device they are displayed on (browser versus mobile versus text only, etc.).
There is often no need for any scripting with languages such as Java Script.
The original XForms specification became an official W3C Recommendation on 14 October 2003, while XForms 1.1, which introduced a number of improvements, reached the same status on 20 October 2009.
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.
GPath is a path expression language integrated into Groovy which allows parts of nested structured data to be identified.
In this sense, it has similar aims and scope as XPath does for XML.
