How to get hold of appropriate Document object for XML Content Assist ? [message #532138]

Hi:

I am trying to embed StructuredTextViewer in a dialog for editing XML code. I am facing problems with getting content assist to work in a particular scenario - when the XML code in the dialog does not correspond to any external file. Getting hold of a proper document and model has been a problem in such a scenario.

Content assist would work fine only if a proper document is provided to StructuredTextViewer.

If I intend to edit a existing XML file in my dialog I can get hold of the appropriate document this way:

IStructuredModel scratchModel = StructuredModelManager.getModelManager() .getModelForEdit(ContentTypeIdForXML.ContentTypeID_XML,new FileInputStream(new File(<FILE PATH>)), null);

IDocument document = scratchModel.getStructuredDocument();

StructuredTextViewer structuredViewer = new StructuredTextViewer(composite, null, null, false, SWT.NONE);

StructuredTextViewerConfigurationXML sourceViewerConfiguration = new StructuredTextViewerConfigurationXML();

structuredViewer.configure(sourceViewerConfiguration);
structuredViewer.setDocument(document);

But the idea is to open up the dialog, take users input in form of XML and do further processing on the input XML - nowhere the input XML code is written to a file. How do I create a Document/Model for such a case so that contents assist works fine ?

Will appreciate any help on this!

Cheers,
Ankit

Hi,
You can use this signature:
org.eclipse.wst.sse.core.internal.model.ModelManagerImpl.get ModelForEdit(IFile)

This method does not check for physical file's existance. You can pass any path and create IPath - Ifile. Later you can set the text to the socument.

Hi:

org.eclipse.wst.sse.core.internal.model.ModelManagerImpl.get ModelForEdit(IFile) returns null if the IFile does not exist.

IFile physical existence is checked in the following method

org.eclipse.wst.sse.core.internal.model.ModelManagerImpl >> private IStructuredModel _commonGetModel(IFile file, String id, IModelHandler handler, URIResolver resolver, ReadEditType rwType, String encoding, String lineDelimiter) throws IOException, CoreException

Hence this does not solve my problem!!!

Any other way to get this working without physically creating a file.

Hi,
Did you try this:
org.eclipse.wst.sse.core.internal.model.ModelManagerImpl.get ModelForEdit(String, InputStream, URIResolver)

by passing null for URIResolver.
