---+!! Include Topics and Web Pages Using =%<nop>INCLUDE{...}%= Variable

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

%TOC%

---++ Syntax Example

=%<nop>INCLUDE{ "page" pattern="reg-exp" rev="2" warn="off" section="clients" PARAMETER1="value" PARAMETER2="Some value"}%=

The =pattern= parameter is optional and allows you to extract some parts of a web page. Specify a %SYSTEMWEB%.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.

The example parameters PARAMETER1 and PARAMETER2 will be defined as a variable within the scope of the included topic. The example parameters shown will result in %PARAMETER1% and %PARAMETER2% being defined within the included topic.

VarINCLUDE explains the other parameters.

__Note:__ All text of a topic is included unless it contains a =%<nop>STARTINCLUDE%= and =%<nop>STOPINCLUDE%=, or you specify a =section= parameter and/or a =pattern= parameter. A pattern will only search between =%<nop>STARTINCLUDE%= and =%<nop>STOPINCLUDE%=.

---++ Usage Examples

---+++ 1. Display regression test results in a TWiki page
<pre>
  &lt;pre&gt;
  %<nop>INCLUDE{"http://domain/~qa/v1.1/REDTest.log.txt"}%
  &lt;/pre&gt;
</pre>

---+++ 2. Display Google's robot.txt file

<pre>
  %<nop>INCLUDE{"http://www.google.com/robots.txt"}%
</pre>

---+++ 3. Display the current time in Tokyo in a TWiki page

   * You type:
      * ==Tokyo: %<nop>INCLUDE{"http://TWiki.org/cgi-bin/xtra/tzdate?tz=Asia/Tokyo" pattern="^.*&lt;\!--tzdate:date--&gt;(.*?)&lt;\!--/tzdate:date--&gt;.*"}%==
   * You get:
      * Tokyo: %INCLUDE{"http://TWiki.org/cgi-bin/xtra/tzdate?tz=Asia/Tokyo" pattern="^.*<\!--tzdate:date-->(.*?)<\!--/tzdate:date-->.*"}%

---+++ 4. Include a topic !MyTopic with two parameters

You include the topic with this line
<verbatim>
  %INCLUDE{ "MyTopic" BETTER="apples" WORSE="Oranges"}%
</verbatim>

An example of a very simple !MyTopic could contain

<verbatim>
   * I like %BETTER% better than %WORSE%.
</verbatim> 

The result would be

   * I like apples better than oranges.
