http://eclipse.org/webtools/community/tutorials/DevelopingWTP/DevelopingWTP.html would be one place to start, but you may want to create the example Plug-in Project beforehand to get your feet wet with plug-in development in general.

To get your feet wet in plug-in development, may I suggest Lars Vogel's
site: http://www.vogella.de. He has a tutorial or two on RCP, etc.

Ok, I did the check-out but now I have some like 10 thousand error, for example:

"AbstractAdapterFactory cannot be resolved into a type" in file JFaceNodeAdapterFactory.java and so on...

In every source file I have error.

Thanks

Sounds like you don't have the dependencies. The XML Editor isn't entirely provided by a single plug-in, you either have to have them all as part of the Target Platform or also checked out into your workspace. The simplest way to get them into your Target Platform is to have WTP installed.

How do I check if it is installed?
I edit every day XML files.

By the way the plugins org.eclipse.wst.xml.* are installed in eclipse/plugin folder

Ok, now I have errors in:

XMLValidatorPreferencePage.java (method clearCatalogCache() is undefined)
XMLCatalogEntriesView.java (INDICATE_NO_DOCUMENT_ELEMENT and USE_PROJECT_SETTINGS cannot be resolved)

Where can I find these sources?

Now in my workspace I have:

org.eclipse.wst.see.ui
org.eclipse.wst.xml.ui

But still I have errors listed above.

Which others plugins do I need?

EDIT: I solved checking-out org.eclipse.wst.xml.core, but this is strange because:

XMLCorePreferenceNames.INDICATE_NO_GRAMMAR was fine, but XMLCorePreferenceNames.INDICATE_NO_DOCUMENT_ELEMENT wasn't, why?
And, org.eclipse.wst.xml.core.jar was already in my plugins folder.
BTW, now I have no errors.

Thanks
Marco

Ok, I followed the tutorial and it works fine but on the console I got some warnings, for example:

ENTRY org.eclipse.osgi 2 0 2011-05-26 13:06:37.321
!MESSAGE One or more bundles are not resolved because the following root constraints are not resolved:
!SUBENTRY 1 org.eclipse.osgi 2 0 2011-05-26 13:06:37.321
!MESSAGE Bundle reference:file:/Z:/eclipse_new/eclipse/plugins/org.eclipse.wst.xsd.ui_1.2.304.v201101251958.jar was not resolved.
!SUBENTRY 2 org.eclipse.wst.xsd.ui 2 0 2011-05-26 13:06:37.321
!MESSAGE Missing required bundle org.eclipse.wst.sse.ui_[1.2.0,1.3.0).
!SUBENTRY 1 org.eclipse.osgi 2 0 2011-05-26 13:06:37.321


And a some more.


At the moment I have checked-out from CVS the following plugins:

1) org.eclipse.wst.sse.ui
2) org.eclipse.wst.xml.core
3) org.eclipse.wst.xml.ui

Do warning mean I need also some other plugins?

Furthermore, for this warning:

MESSAGE Bundle reference:file:/Z:/eclipse_new/eclipse/plugins/org.eclipse.jst.jsf.ui_1.3.1.v20100906.jar was not resolved.


I checked and that JAR file exists in that path (with the exact same name)...

If I check-out the required bundle from eclipse CVS relative warning disappears...but I do not understand why I get this warning as the plugin is in eclipse_home/plugins... Sad

Thanks
Marco

It looks like you may have checked out the versions from HEAD, but not
using an Indigo build. "Missing required bundle
org.eclipse.wst.sse.ui_[1.2.0,1.3.0)" points to this being just that
kind of version mismatch.

Ok, at the moment I am using Indigo release and I do not have those warnings anymore.

I explain better my goal.

I have an XML file which represents a series of step to be taken.
What can be done inside each step is defined in a second XML file.
So, the content assist is for the values of attributes and not for the attributes themselves, or for tags as the "classic content assist"

Is it possible to query this XML file using XPath and using as argument of my XPath function what has be written by user?
I tried to query an XML file using XPath and it works. But, now, I would like to query according to what user wrote.

I make an example:

<employee level=" At this point the content assist should display the available level. So, I have to write an XPath expression to query an external XML file and ask for the all available levels, then, present them in the a "content-assist-like"

No problem about XPath, I know it; my problem is to get the attribute and then represent the values...

How do I get the last inserted attribute?



Thanks
Marco

Ok, some news.

I saw that plugin org.eclipse.wst.sse.ui provides the extension point completionProposal.
Attached to this there are also some examples.

These example propose what I need, that is, suggestion for attribute values.
I think values comes from DTD file.

But, I have to improve this taking values from an XML file.
The attributes values are the tags in my external XML file.

Hi,

Eclipse Indigo (I think previous releases too) contains a project called XMLExample; just create a new project and then choose "Example".
It contains some XML files with DTD/Schema too.
