Searching in an HTML document

Hi,

If I have an HTML document, and want to search for and highlight a
string in the document, is there an easy way of getting from the
character positions in the raw HTML to the corresponding selection point
in a JEditorPane?

e.g. My html is:

<html><head></head><body><h1>header</h1>text</body>

If I search for "header" in the raw html, I get position 29. But in the
JEditor Pane, to highlight it, I need to setCaretPosition(0),
moveCaretPosition(6).

Is there a way of doing this? i.e. working out that the rendered caret
position for an arbitrary html document substring?

Regards

Rogan

if you only parse text and not html code, maybe
you should parse editorPane.getText() instead of the raw html?
i don't know if this works, it is only a guess...

Thanks for the suggestion, but this does not work :-(

Strip all html tags, this is one of the ways to do that:
String noHTMLString = htmlString.replaceAll("\\<.*?\\>","");
