Is there any package similar to the XML package that is able to
"extract" relevant information from HTML files. Namely, I'm
interested
in obtained data that is represented as a HTML table, into some R-type
structure.
Thank you.

If my memory serves me correctly, I believe that Dan Veillard's libxml library provides an adaptation of the XML parser that handles HTML. In that case, I can add something to the XML package that allows us to access the HTML parser and use the same interface for both XML and HTML from within R. I'll take a look and see if this is relatively easy to do. Luis Torgo wrote:> Is there any package similar to the XML package that is able to > "extract" relevant information from HTML files.

Hi Luis, I just uploaded the latest version of the XML package to the Omegahat web site at http://www.omegahat.org/RSXML/XML_0.7-0.tar.gz and this now has support for parsing HTML. I only added support for the DOM style of parsing, i.e. reading the entire tree and then applying R functions to convert it. Hopefully that will be enough to suit your needs. Please let me know if there are any problems with the package. Thanks for the suggestion to include HTML support. Duncan.
