There are lots of ways doing HTML parsing in Python. A common one is e.g. using mxTidy to convert the HTML into valid XHTML and then use ElementTree to parse the data. http://www.egenix.com/files/python/mxTidy.html http://docs.python.org/lib/module-xml.etree.ElementTree.html For simple tasks you can also use the HTMLParser that's part of the Python std lib. http://docs.python.org/lib/module-HTMLParser.html Which tools to use is really dependent on what you are trying to solve. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Jan 23 2008) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ :::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,MacOSX for free ! :::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
