There's a feature request for this, I think, but I use a chunk of code
similar to this:

    /** Similar to HtmlPage.getAnchorById() but uses the label of the anchor to obtain the element
     * @param page The page containing the anchor being searched for
     * @param label The label (user visible part) of the anchor
     * @return The HtmlAnchor represented by the given label, or null if no label is found. */
    private HtmlAnchor getHtmlAnchor(HtmlPage page, String label) {
        // Make sure that the inputs are sane
        if (label == null)
            return null;

        List anchors = new ArrayList();
        anchors.add("a");
        List returnedAnchors = page.getHtmlElementsByTagNames( anchors );
        Iterator i = returnedAnchors.iterator();
        HtmlAnchor anchor = null;
        while(i.hasNext()) {
            anchor = (HtmlAnchor)i.next();
            if (label.equals(anchor.asText()))
                return anchor;
        }
        return null;
    }

Cheers,

Simon
