<code>readWeb</code> is a FunctionGenerator which specifies content retrieval from a <code><a rd-options="" href="/link/WebSource?package=tm.plugin.webmining&version=1.3" data-mini-rdoc="tm.plugin.webmining::WebSource">WebSource</a></code>
content elements. Currently, it is defined for XML, HTML and JSON feeds through <code>readWebXML</code>,
<code>readWebHTML</code> and <code>readWebJSON</code>. Also content parsers (<code>xml_content</code>, <code>json_content</code>)
need to be defined.


Facilitate text retrieval from feed
formats like XML (RSS, ATOM) and JSON. Also direct retrieval from
HTML is supported. As most (news) feeds only incorporate small
fractions of the original text tm.plugin.webmining even retrieves
and extracts the text of the original text source.

readWeb: Read content from WebXMLSource/WebHTMLSource/WebJSONSource.
