Include Topics and Web Pages Using %INCLUDE{...}% Variable

Use the %INCLUDE{...}% variable to embed the content of another topic or web page inside a Foswiki topic. The whole content or only parts of a page can be included. If needed, set a proxy server in DefaultPreferences.

Syntax

%INCLUDE{ "page" pattern="reg-exp" rev="1.2" }%

• "page":
  The nameless parameter specifies the page to include. It is
  • The name of a topic located in the current web, e.g., %INCLUDE{"WebNotify"}%
  • A Web.Topic name specifying a topic in another web, e.g., %INCLUDE{"System.SiteMap"}%
  • A full qualified URL with http protocol, domain name and optional port number, e.g., %INCLUDE{"http://twiki.org:80/index.html"}%. Supported content types are text/html and text/plain. The full page is included by default, but the HTML header and scripts are stripped in case it is a web page.

• pattern="reg-exp":
  The pattern parameter is optional and allows you to extract some parts of a web page. Specify a RegularExpression that scans from start ('^') to end and contains the text you want to keep in parenthesis, e.g., pattern="^.*?(from here.*?to here).*". You need to make sure that the integrity of a web page is not compromised; for example, if you include a table, make sure to include everything including the table end tag.

• rev="1.x":
  The rev parameter is optional and allows you to include an earlier revision of a topic. This can be used to include an official version of a topic, e.g. one that has been signed of by management. This parameter does not apply to URLs.

Note: All text of a topic is included unless you specify %STARTINCLUDE%, %STOPINCLUDE% and/or a pattern parameter.
