Help with Python Code Whitespace
Hello All,

I have some python code that pulls together titles and displays them on web pages.

Here is the section of code I am struggling with:

#string to grab title

titlePattern =r'''\s*(\([^\)]+\))?(?P<title>.*)'''

#returns the title part of the subject line

def getTitle (self,data):

return re.search (

PartParser.titlepattern,

self.getSubject (data),

re.X

).group ("title)


This code will print out a title with whitespace in the midde od the title

ie: This is a (whitespace here, spaces or tabs) great day.

I am trying to use join and split to make the tile read

ie: This is a great day.

I believe I can remove the whitespace with

newtitlePattern = ' '.join(titlePattern(1).split())

and

PartParser.newtitlePattern

but I an not sure where to put this in the code.

Please help

sgmls::refs

Refs(3pm)						User Contributed Perl Documentation						 Refs(3pm)

NAME

       SGMLS::Refs - Forward reference handling

SYNOPSIS

	 use SGMLS::Refs;

       To create a new reference-manager object using the file "foo.refs":

	 my $refs = new SGMLS::Refs("foo.refs");

       To create a new reference-manager object using the file "foo.refs" and logging changes to the file "foo.log":

	 my $refs = new SGMLS::Refs("foo.refs","foo.log");

       To record a reference:

	 $refs->put("document title",$title);

       To retrieve a reference:

	 $title = $refs->get("document title");

       To return the number of references changed since the last run:

	 $num = $refs->changed;

       To print a LaTeX-like warning if any references have changed:

	 $refs->warn;

DESCRIPTION

       This library can be used together with the SGMLS package to keep track of forward references from one run to another, like the LaTeX ".aux"
       files.  Each reference manager is an object which reads and then rewrites a file of perl source, with the file name provided by the caller.

       Example:

	 # Start up the reference manager before the parse.
	 sgml('start', sub { $refs = new SGMLS::Refs("foo.refs"); });

	 # Warn about any changed references at the end.
	 sgml('end', sub { $refs->warn; });

	 # Look up the title from the last parse, if available.
	 sgml('<div>', sub {
	   my $element = shift;
	   my $id = $element->attribute(ID)->value;
	   my $title = $refs->get("title:$id") || "[no title available]";

	   $current_div_id = $id;

	   output "\section{$title}

";
	 });

	 # Save the title for the next parse.
	 sgml('<head>', sub { push_output('string'); });
	 sgml('</head>', sub {
	   my $title = pop_output();
	   my $id = $current_div_id;

	   $refs->put("title:$id",$title);
	 });
