Hi,

I am implementing a AuthorOperation which should jump to a specific element within an xml file that needs to be opened in text mode.
I already managed to open the file:

Code: Select all

PluginWorkspaceProvider.getPluginWorkspace().open(url, EditorPageConstants.PAGE_TEXT);

(and also to modify the content with editor.reloadContent()

But how can I place the cursor at a specific position? The target element even has an id attribute. So basically I want to trigger the behavior is if i'm clicking on a link "my-file.xml#my-id".

Thanks and regards,
Patrik

Hi Patrik,

After the file is opened you can do something like:

Code: Select all

    WSEditor editorAccess = PluginWorkspaceProvider.getPluginWorkspace().getEditorAccess(url, PluginWorkspace.MAIN_EDITING_AREA);

    if(editorAccess != null){

      WSEditorPage currentPage = editorAccess.getCurrentPage();

      if(currentPage instanceof WSXMLTextEditorPage){

        WSXMLTextEditorPage xmlTP = (WSXMLTextEditorPage) currentPage;

        WSXMLTextNodeRange[] ranges = xmlTP.findElementsByXPath("//*[@id='myID']");

        if(ranges != null && ranges.length > 0){

          int startLine = ranges[0].getStartLine();

          int startColumn = ranges[0].getStartColumn();

          int offsetInDoc = xmlTP.getOffsetOfLineStart(startLine) + startColumn;

          //This should place the caret immediately before the element.

          xmlTP.setCaretPosition(offsetInDoc);

          xmlTP.scrollCaretToVisible();

        }

      }

    }

Thanks alot, Radu. This works fine - and knowing about the WSXMLTextNodeRange solves some other problems as well... :D
