想要在代码中打开一个 eclipse xml 文件并参考它的 IFile 导航到一个特定的行号

我通过它的 IFile 实例在 Eclipse IDE 中引用了一个 xml 文件.我知道想在我的视图上添加一个操作，在 xml 编辑器中打开文件并导航到特定的行号.有人对如何解决这个问题有任何想法吗?

I have a reference to an xml file in eclipse IDE through its IFile instance. I know want to add an action on my view that opens the file in the xml editor and navigate to a specific line number. Anyone have any ideas on how to go about this?

推荐答案

假设你知道文件的 URL:

Assuming you know the file's URL:

IWorkbenchPage page = activeWorkbenchPage();
if (page == null) {
    throw new RuntimeException();
}

IFile file;
IFile[] files = ResourcesPlugin.getWorkspace().getRoot()
            .findFilesForLocationURI(url.toURI());
file = files[0];

IMarker marker;
marker = file.createMarker(IMarker.TEXT);
HashMap<String, Object> map = new HashMap<String, Object>();
map.put(IMarker.LINE_NUMBER, lineNumber);
marker.setAttributes(map);
IDE.openEditor(page, marker);
marker.delete();

当然，您还需要捕获/抛出一些异常，但为了简单起见，我在这里省略了.

Of course you will need to catch/throw a couple of Exceptions as well, but I omitted this here for simplicity.
