        <p><b>Example #1</b><br/>
	    The example below scrapes the page for the 
          <a href="http://weather.noaa.gov/cgi-bin/fmtbltn.pl?file=forecasts/city/mo/columbia.txt">Columbia, 
          Missouri weather forecast</a> from the <a href="http://weather.noaa.gov/">National Weather Service</a> site. In this scrape, the 
          <b>anchors</b> attribute was set to true, and the <b>begin</b> and <b>end</b> anchor attributes 
          were set to the &lt;PRE> and &lt;/PRE> tags that surround the forecast.
        </p>

        <scrp:result scrape="weather1"/>

        <hr/>
        <p><b>Example #2</b><br/>
	    This example scrapes the same page as the first example and uses the same anchors, 
          but in this case the <b>anchors</b> attribute was set to false so that the anchors are stripped from 
          the scrape result. Browsers typically treat text within &lt;PRE> tags with a monospaced font 
          and line breaks in the HTML are retained. Since the &lt;PRE> and &lt;/PRE> tags are the anchors and they 
          are removed from the scrape result, the formatting is noticeably different.  
        </p> 

        <scrp:result scrape="weather2"/>

        <hr/>	
        <p><b>Example #3</b><br/>
	    This example scrapes the same page as the first two examples and uses the same anchors, 
          but in this case the <b>anchors</b> attribute was set to false and the <b>strip</b> attribute was set to true so that the anchors and HTML tags are stripped from the scrape result. 
        </p> 

        <scrp:result scrape="weather3"/>
