Hi,

I need the content assist feature for some of my xsd, how can I tell the
StructuredTextEditor to parse my xsd's files

Thanks

Alexandre,

If I understand the posts I've read here, I think you'd register the
namespace of the schema in the XML catalog...

rigth now I've written an editor that extends the StructuredTextEditor
-I set the source viewer configuration to a custom one
-my source viewer configuration class extends
StructuredTextViewerConfigurationXML
-I've created a scanner for my editor
-I've created a completion processor

With the normal TextEditor you only needs to define what are the
completion propals

What I do I missed for the StructuredTextEditor

Thanks

The completion work only if I add the doctype declaration at the begin
of my file (my file represent a portion of code and cannot contain xml
declaration and a doctype)

Is it possible to hide these declaration and make the completion still
working.

To make it work I've to declare

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xgui:module PUBLIC "-TOTO-" "unknown.dtd">

Any idea ?

There are a couple of ways to do this, depending on how your XSD is setup.

If it is namespace aware, then as ED said, you can register it in the
XML Catalog by namespace, and have it load the appropriate XSD based on
the namespace in the xml. This will require you specifying at the
minimum a xmlns="" attribute with the appropriate namespace filled in,
in the XML instance.

The other option is to use the xsi:schemaLocation="" attribute to
specify where the schema can be found locally.

Take a look a the following tutorial on the XML Catalog. You need to
make sure you specify it correctly. Again if you have an XSD that is
tied to a namespace, you can use the xmlns="" attribute to set the
default namespace, and the eclipse xml editor should pickup the grammar
from there by looking in the xml catalog.

Hi David,

There is no way to avoid the declaration in the xml file ? Like doing
the content assist for a normal TextEditor ?

Look at the XML Catalog extension point.

http://www.eclipse.org/webtools/community/tutorials/XMLCatal og/XMLCatalogTutorial.html

The other way is you might need to create a Custom Resolver that knows
about your XML markup, and loads the appropriate grammar. We use this
technique in the XSL Tooling incubating project, to specifically load a
particular version of a grammar based on the XSL verision attribute on
the stylesheet element. However, you still need to define the
namespace that the grammar should be attached too.

My document contains the following code

<xgui:module>
<xgui:hbox></xgui:hbox>
</xgui:module>

I want to hide the first two lines, I'm trying the following code

public void activateEditor() {
String str = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><!DOCTYPE
xgui:module PUBLIC \"-TOTO-\" \"unknown.dtd\"";

boolean readOnly = true;
if (property != null) {
String v = property.getValue();
str = str.concat(v);
//str = v == null ? "" : v;
readOnly = false;
}

// Update the contents of the InputStreamEditorInput
InputStreamEditorInput input = (InputStreamEditorInput) getEditorInput();
InputStream is = new ByteArrayInputStream(str.getBytes());
input.setContents(is);
input.setReadOnly(readOnly);
getSourceViewer().getDocument().set(str);
String text = getSourceViewer().getDocument().get();
int length = getSourceViewer().getDocument().getLength();
getSourceViewer().setVisibleRegion(str.length(), length -1);
}

but my code is still visible :/ any idea why ?

(Do you think this solution will still enable the content assist)

Thanks

Well, there is one thing that stands out here to begin with. It looks
like you are trying to use namespaces with DTDs, which aren't supported.

http://www.rpbourret.com/xml/NamespacesFAQ.htm#dtd

The qualified support your are using in the DTD, is probably throwing
the processors for a loop as they may be thinking you are trying to do
namespaces. The qualifiers look like XML Namespace prefixes. So if
you can I would recommend migrating your DTD to a XML Schema.

A online service you can use to accomplish this is here:

http://www.hitsw.com/xml_utilites/

If you need namespace support you need to use XML Sck

Content Assist shouldn't care, but you're getting the visible length
after having changed the document contents, so you're just cutting
off the last character of the new contents, str, at best. The best
solution would involve bug 210413, I think.

This is exactly, what I need. Alex wanted on DTD, I want to get assistance through xsd, but without specifying the schema location or namespace in the file.??

Is there a potensial solution to this problem?

Thanks.
