Subject: More Regexp and file load problems

Hi All,

I am struggling here and would be most appreciative of any help.

I have a regular expression problem I can't seem to figure my way out  
of. I had sent a similar request this morning, and gratefully  
received two emails from David Black and Axel Etzold. Unfortunately,  
I am still having difficulty.

I am trying to extract the font name attribute  out of the following  
xml (this is an excerpt of a larger file). The weird thing, is that  
my regular expression correctly matches the text if I use TextMate's  
regular expression 'find in project feature' and with the freeware  
Reggy regular expression test tool found on Google code. It also  
matches correctly, if I text against a subset of the xml being  
parsed. I.E., see this first example.

string = %q(</TextObj>
</Object>
<ObjectStyle id="0" fontHeight="11" graphicFormat="3843"  
fieldBorders="132">
<CharacterStyle mask="16183">
<Font-family codeSet="Roman" fontId="0">Helvetica</Font-family>
<Font-size>9</Font-size>
<Face>256</Face>
<Color>#000000</Color>
</CharacterStyle>")


regexp = Regexp.new(/^\s*<Font-family codeSet=\"\w*\" fontId=\"\d*\"> 
(\w*)<\/Font-family>\s*$/)

if string =~ regexp
       puts "#{$1}"

   end


Result: Helvetica




However, if I run this script, there is no result.

regexp = Regexp.new(/^\s*<Font-family codeSet=\"\w*\" fontId=\"\d*\"> 
(\w*)<\/Font-family>\s*$/)
file = File.new('/Users/donlevan/Desktop/DDRs/Apple Dealer Price  
List.xml')

file.each do |line|
   if line =~ regexp
       puts "#{$1}"

   end
end



I have looked at Hiproct and XML simple, unfortunately I can not get  
TextMate configured correctly so I keep getting Loaderrors when I try  
to use ruby gems.

Thanks,

Don
