Question

How would be the pattern to extract a chunk of text between two arbitrary words that may or not be in the same line. For example:

Welcome to TWiki, a flexible, powerful, 
and easy to use Web-based collaboration platform. 

Use TWiki to run a project development space, 
a document management system, 
a knowledge base, or 
any other groupware tool, on an intranet or on the internet. 

Let´s say I want the text between powerful and tool including both words

powerful, 
and easy to use Web-based collaboration platform. 

Use TWiki to run a project development space, 
a document management system, 
a knowledge base, or 
any other groupware tool

Answer

Do an INCLUDE with a pattern; the pattern search goes over multiple lines. Here is how to grab the text from your example on this topic:

%INCLUDE{ "%TOPIC%" pattern="^.*?(powerful.*?tool).*" }%

does this:

IncludeTopicsAndWebPages has more.
