perl : replace multiline text between two marker points

Hi there

I just wondered if someone could give me some perl advice

I have a bunch of text files used for a wiki that have common headings such as

Code:

 
 
---++ Title
blah
 
---++ Summary
blah
 
---++ Details
Here is the multiline
block 
of text I 
wish 
to 
replace that will
be different
in 
every file
 
---++ More info 
blah

So basically, All of the text between the "---++ Details" marker and the "---++ More info" marker I want to strip out and replace with a static multiline piece of text which i will put in a variable ...

Does anyone know of a quick and dirty way within perl of doing this, so far in my code i am passing the filename to the script for opening, I have create a 'here doc' style variable to contain my desired mutiline block of text and that is where my mind has gone blank ...

I guess i need a way of detecting the "---++ Details" line, deleteing everything after it up to and not including the "---++ More info" line and then putting the contents of $newtext into that space ?

Any guidance would be greatly appreciated

pdbtxt2html

pdbtxt2html(1)						      General Commands Manual						    pdbtxt2html(1)

NAME

       pdbtxt2html - Doc Text to HTML converter for Palm Pilots

SYNOPSIS

       pdbtxt2html [ -t ] file.txt [ file.html ]
       pdbtxt2html -v

DESCRIPTION

       pdbtxt2html converts text converted from a Doc(4) file via txt2pdbdoc(1) to HTML.  If no HTML filename is given, the generated HTML is sent
       to standard output.

   Document Title
       The first line of the file is used for the HTML document title.

   Bookmarks
       The last line of the file is examined and, if it contains a string enclosed between < and >, that is taken to be the bookmark marker.   The
       entire file is then scanned looking for lines beginning with it (ignoring leading whitespace).  These lines are converted to HTML headings.

       The  number  of whitespace characters after the first bookmark marker is used for heading level 1.  The level of subsequent headings is set
       to the number of whitespace characters between the bookmark marker and the bookmark text minus the number for the first bookmark plus one.

   Embedded URLs
       Valid URLs (according to RFC 1630) embedded in the text are turned into hyperlinks.  The ftp, gopher, http, https,  mailto,  news,  telnet,
       and wais URLs are recognized.

OPTIONS

       -t   Compile a table of contents and insert it between the first heading and the body.

       -v   Print the version number to standard output and exit.

EXAMPLE

       To convert a Doc file to HTML:

	    txt2pdbdoc alice.pdb alice.txt
	    pdbtxt2html alice.txt alice.html
