ContentTemplate (Brazil 2.3)

Template class for extracting content out of remote html pages. This class is used by the TemplateHandler, for extracting the "content" out of html documents for later integration with a look-and-feel template using one or more of: SetTemplate, BSLTemplate, or ReplaceFilter, The plan is to snag the title and the content, and put them into request properties. The resultant processed output will be discarded. The following properties are gathered:

title: The document title
all: The entire content
bodyArgs: The attributes to the body tag, if any
content: The body, delimited by content.../content>. The text inside multiple <content> ... </content> pairs are concatenated together.
script: All "<script>"..."</script>" tags found in the document head
scriptSrcs: A white-space delimited list of all "src" attributes found in "script" tags.
style: All "<style">..."</style"> tags found in the document head
meta-[name]: Every meta tag "name" and "content"
link-[rel]: Every link tag "rel" and "href"
user-agent: The origin user agent
referer: The user agent referrer (if any)
last-modified: The document last modified time (if any) in std format
content-length: The document content length, as fetched from the origin server

Properties:

prepend: Prepend this string to the property names define above, that are populated by this template. (defaults to "").
