We added nodes that ease the creation and analyzation of xml documents.
Documents are represented by Elements and Attributes - not strings, which helps performance...
You now can easily get some parts of your document and route those as a spread of Elements to other parts of your patch, where they get further analyzed.
You always can convert an element to a simple string via AsString (Object) - or back to an element via AsElement (XML). But typically you only want to do that once: when reading from disk or writing to disk. For the rest working with Elements and Attributes is much more comfortable.
Note that by concatinating several Element (XML Split) nodes - which also outputs an elements' child elements - will give you the possibility to dig into the xml structure. E.g. you could retrieve all child elements of an element, check its properties and dependant of some test select some of the childs via Select (Node). You therefore could patch a query into your xml structure...
However this can get complicated and so we added some more nodes:
With GetElements & GetAttributes we added different ways of searching for child tags and attributes.
When searching by name you get those that have a certain tag or attribute name and are direct child elements or attributes of the specified element.
do that with GetElements (XML ByName) & GetAttributes (XML ByName)
While those nodes are flexible and spreadable in means of what you are searching for, they might be a bit unhandy when you already know that at a certain point in your patch only a certain tag with certain attributes are of interest.
For those cases we added Prune (XML) which lets you set those tag and attribute names statically in configuration pins with the bonus that you get friendly pin names and dont need to further process your attribute data.
For being really sure that your patch system can work with a certain xml-File or string you can check validity with IsValid (XML RelaxNG). link: RelaxNG
Both XML Syntax (.rng-Files) & Compact Syntax (.rnc-Files) are supported.
Thanks to our MESO for putting those node on our agenda and for sponsoring.
