Xml parser validating vs non validating advantages
Check out their website to get details on supported standards, reference documentation, etc.
The XPath assertion applies a specified XPath expression to the received message and validates the resulting nodes against an expected value.
Let's have a look at each together with some examples!
Quick Tip: Both the XPath and XQuery Match assertions make use of the Saxon XPath / XQuery processor which supports most of the latest standards in this area.
It is up the programmer to do useful things with these events.
This month, however, we tackle just one, the question of questions -- the question that nearly everyone asks at some point: Which XML parser should I use?
I suppose the two main approaches are DOM and SAX parsers.
(In this case, you'll find that XML:: Parser is built on the same expat, written in C, that's at the heart of the Mozilla browser.) Or maybe you're using the Oracle 8 database management system to read in and emit XML from its relational tables -- why bother even looking at some parser other than the one that comes with Oracle, and risking potential incompatibilities?
It's like asking, "I want to buy a car and I want to make sure the wheels will stay on. The developer of the browsing application will almost certainly have made the decision for you, and you can probably override it only with difficulty (and perhaps intellectual pain).
For instance, Microsoft's Internet Explorer 5.x browsers use a parser built into the file, and the Mozilla browser is built on a parser, written in C, called "expat." Nevertheless, in some cases you do need to select a parser.
You may find that you prefer one tool's error reporting format to another's. By the way, in theory you need to submit a given document to only one parser to ensure its "correctness." After all, the XML Recommendation is what it is, right?
No wiggle room for interpreting a given chunk of code as correct or not, right?
(Note: Any parser that validates will also check for well-formedness.
