PUBLIC MARKS from parmentierf with tags tag & html

In this tutorial, you learn to build a link graph with XML, PHP, and JavaScript code. Link graphs are paragraphs of keywords in which the size of each word depends on some data value -- in this case, the frequency of the term. The more often the term occurs, the larger the font size of the word. This tutorial shows how to build an RSS parser that in turn builds a keyword list along with the word frequencies. It also demonstrates how to use XSLT to create an HTML page that shows the link graph and relates its term to its original article.
