Question about structured models and validation [message #66039]

Hi,

Have a question about XMLModels and validating programatically. In short
I'm adapting a project builder that parses a pile of XML files and (if
they are well formed and valid) traverses the DOM tree building some
objects.

(I'm trying to avoid a long story here so bear with me...I'm learning by
trying things out)

Currently (preWTP) I'm parsing the files to DOM myself and catching
parse and validation errors.

I'd like to use the XMLModels provided by WTP instead as I can ask for a
DOM rep by calling getDocument().

ie. by doing stuff like this:

Document doc = null;
IModelManager mm = StructuredModelManager.getInstance()
.getModelManager();
IStructuredModel model = null;
try {
model = mm.getExistingModelForRead((IFile) myFile);
if (model == null || !(model instanceof XMLModel))
return;

doc = ((XMLModel) model).getDocument();
} finally {
if (model != null)
model.releaseFromRead();
}

and I get a w3c Document object regardless of the fact that a file may
not be well formed or valid.

Question is: How does one use WTP to check if the file is well formed
and valid before (or after) getting the XMLModel and obtaining a w3c
Document?

thx,

Geoff

Hi Geoff,

You can programmatically call XML validation using the XML validator
located in org.eclipse.wst.xml.validation as follows.

XMLValidator validator = new XMLValidator();
// You may want to set a URI resolver for custom resource resolution. In
Eclipse the validator is configured to use the
org.eclipse.common.uri.resolver
XMLValidationReport report = validator.validate(filename);

The validation report will tell you if the file is valid and will provide
error and warning messages if it isn't.

Please note that the API for the XML validator (and most of the WTP
project) is not final yet and may change.
