Hi John,
Use the HTML <TITLE> tag and the <META> tags for storing your Category and
Summary, and then read and assign the files as a <@DOM> variable - then use
XPointer to extract the information you want.
This is much more elegant and makes use of the HTML <META> tags they way
they are meant to be used. And then you don't have to worry about removing
the information.
Something like:
<@ASSIGN local$TempHTMFile VALUE="<@DOM VALUE='
<HTML>
<HEAD>
<TITLE>I'm a vegetarian</TITLE>
<META NAME="helpCategory" CONTENT="Cooking" />
<META NAME="helpSummary" CONTENT="I steam all my vegetables" />
</HEAD>
<BODY>
<P>Some content, blah, blah, blah...</P>
</BODY>
</HTML>
'>">
Note the <@DOM VALUE=''> can be substituted with an <@INCLUDE> that points
to your help file, but I'm showing HTML here to illustrate how this is
done.
Then to extract the information, assign the following to a variable.
<@ELEMENTVALUE OBJECT='local$TempHTMFile'
ELEMENT='root().child(1,HTML).child(1,TITLE)' TYPE='TEXT'> - return the
Title: I'm a vegetarian
<@ELEMENTATTRIBUTE OBJECT='local$TempHTMLFile'
ELEMENT='root().child(1,HTML).child(1,META,NAME,helpCategory)'
ATTRIBUTE='CONTENT' TYPE='TEXT'> - returns the Category: Cooking
<@ELEMENTATTRIBUTE OBJECT='local$TempHTMLFile'
ELEMENT='root().child(1,HTML).child(1,META,NAME,helpSummary)'
ATTRIBUTE='CONTENT' TYPE='TEXT'> - returns the Summary: I steam all my
vegetables
The only prerequisite is that all the HTML files need to be XML compliant -
a.k.a XHTML. Making any HTML page XHTML compliant is coding practice in my
opinion and is a good habit to get into.
But you probably could cheat by doing something like:
<BODY>
<!-- <![CDATA[ -->
<P>Some badly formed HTML.
<P>More badly formed HTML, blah, blah,
<!-- ]]> -->
</BODY>
Hope this helps. Cheers....
