for example, here is how you would fix all hrefs in an html file:

htmldocument doc = new htmldocument();
doc.load("file.htm");
foreach(htmlnode link in doc.documentelement.selectnodes("http://[email protected]")
{
htmlattribute att = link"href";
att.value = fixlink(att);
}
doc.save("file.htm");

if you want to participate to the project - because that's the whole purpose of putting the source there, right - use the forums or drop me a note (simon underscore mourier at hotmail dot com)!

happy coding, scraping, scanning, html-ing, xhtml-ing, etc... :^)
