If you look at the text of an html page, which normally is show in the browser, the following for example is a link to the pages of the TextTransformer:


<a href="http://www.texttransformer">


If the text enclosed into quotes - the URL - begins with "http://www.", the link refers to an external web page. Exactly that is, what shall be found here. Two simple productions fulfill the purpose :


GrepUrls ::=







Url ::=


"<a href=\"http://www."




A html page consists of the desired URL's and other text. The URL is introduced by "<a href=\"http://www." and extends up to the next quote mark.


The case-sensitivity is deactivated in the project options, as HTML is case insensitive. So tags like


"<A HREF=\"http://www."


are found too.
