public class ContentTemplate extends Template
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

    • init

      public boolean init(RewriteContext hr)
      Description copied from class: Template
      Called before this template processes any tags.
      Specified by:
      init in interface TemplateInterface

      public void tag_title(RewriteContext hr)
      Toss everything up to and including this entity.

    • tag_script

      public void tag_script(RewriteContext hr)

      toss everything up to and including here, but turn on content accumulation.
