Doug LundinSubject: Screen scraping using Stylus?

Advice using Stylus

My goal is to build a data mining application using PR Newswire (http://biz.yahoo.com/prnews/archive.html)

Essentially, I will be doing ***LIMITED*** screen scraping (given a date, etc.)

There are some good tools available such as WebQL but I am wondering if Stylus can do this as well. I would prefer a more general tool if it is available.

I have been told screen scraping is generally easier with XLST 2.0 rather than XQuery. Do you agree?

There doesn't appear to be any samples on stylusstudio.com that offers insight.

Suggestions on how to evaluate Stylus for this task?

Thanks in advance
Doug

Using Stylus Studio you can take advantage of the HTML to XML converter and feed the HTML as a well formed XML into an XSLT or XQuery. You can take a look at http://www.stylusstudio.com/xml_import_export.html for more details about how to use converters in Stylus Studio.

About the XSLT 2.0 vs. XQuery question, if regular expression handling is important to you for the kind of work you need to do, then maybe XSLT 2.0 is a good choice; you may want to take a look at this Michael Kay's article for a well written comparison of the two languages: http://www.idealliance.org/proceedings/xtech05/papers/02-03-01/

Hope this helps,
Minollo
