Present one ore more clipped parts of one or more web pages in a portlet.
The clipped part is a section of a web page between a start tag and a stop tag.
This portlet supports nested tags:
<table>
...
<table>
...
</table>
...
</table>
In this case you can clip the complete table, or only the inner table.
Example of how to find a tag:
Find: <img src="http://www.apache.org/images/asf_logo_wide.png" width="537"
height="51" alt="Apache Software Foundation"/>
If it's the first image (or there's only one image) in the page, you can clip it with:
Tag...="img"
But you can also find the image with:
Tag...="img src=http://www.apache.org/images/asf_logo_wide.png width=537
height=51 alt=Apache Software Foundation"
Tag...="img src=http://www.apache.org/images/asf_logo_wide.png"
Or (simpler!):
Tag...="img asf_logo_wide.png"
Tag...="img 537 Apache"
The match is between the tags (img) and any portion of its attributes (width=537, 537, asf_logo_wide.png, ...)
Parameters that control what parts of the web pages are converted into a portlet. All these parameters are followed by a number: startTag1, startTag2, ...
