First of all, you can use the HtmlDocument.All collection, which allows you to retrieve any element on the page using its id attribute. If you need to retrieve an element that doesn t have an id attribute, you can also use the HtmlDocument method GetElementsByTagName(), as demonstrated in the next example. <Transaction> <HistoricTxn> <reference>Reference Number</reference> <authcode>Authentication code</authcode> <method>fulfill</method> </HistoricTxn> </Transaction> </Request> The next example shows how you can use screen scraping to extract just those elements that interest you. In this case, the task is to retrieve all the hyperlinks on a page by searching for anchor tags. Remember, a typical anchor tag looks like this: <a href="http://www.mysite.com/mypage.html">Click here!</a> The hyperlink destination (which is found in the href attribute of the anchor tag) is then added to a list box, but the inner text is ignored.

The following is the calcTextureLength() method that uses this equation: private int calcTextureLength(String texFnm, int freq) { if (freq < 1) // if 0 or negative freq = 1; else if (freq > FLOOR_LEN) // if bigger than the floor length freq = FLOOR_LEN; return (FLOOR_LEN / freq); } Due to calcTextureLength() s use of integer division, the freq value should be a factor of the floor length. Since FLOOR_LEN is 20, freq should be 1, 2, 4, 5, 10, or 20. Figures 6-11 and 6-12 show the rendering of an r.gif texture containing a single letter R. Figure 6-11 shows r.gif rendered with a frequency of 20, while Figure 6-12 uses a frequency of 4. // integer division private void cmdGetAllLinks_Click(object sender, System.EventArgs e) { if (webBrowser.ReadyState == WebBrowserReadyState.Complete) { // Use an hourglass mouse pointer, because it takes a short delay // to build the document tree. this.Cursor = Cursors.WaitCursor; lstLinks.Items.Clear(); HtmlElementCollection elements = webBrowser.Document.GetElementsByTagName("A"); foreach (HtmlElement element in elements) { lstLinks.Items.Add(element.GetAttribute("href")); } this.Cursor = Cursors.Default; } } To make the example more interesting, every time the user clicks a link in the list box, the corresponding item is modified in the Web page. In this case, a string of three angle brackets (>>>) is inserted to mark the selected hyperlink. When a new selection is made, the previous hyperlink is returned to normal. HtmlElement previous = null; private void lstLinks_SelectedIndexChanged(object sender, System.EventArgs e) { HtmlElementCollection elements = webBrowser.Document.GetElementsByTagName("A"); if (previous != null) previous.InnerText = previous.InnerText.Substring(3); previous = elements[lstLinks.SelectedIndex]; previous.InnerText = ">>>" + previous.InnerText; } Figure 17-4 shows the form at work.
