I made these regexes to match and replace html font tags, but rather than doing what they're supposed to, they end up cutting out the entire html document, save for the last line or so of text.

these are the parameters i need to meet:
-the only important attributes are COLOR, SIZE, and FACE (thus the ones i need to match and send to the correct subroutine
-the above attributes will ALWAYS be in the order of COLOR, SIZE, FACE
-each font tag could have all or any combination of above attributes
-some font tags also have BACKGROUND-COLOR and PTSIZE attributes, which could match falsely as COLOR and SIZE if they're not prefixed by whitespace 

$instream =~ s/<FONT(.*?)\sCOLOR\s?=\s?('|")?(\#......)\2(.*?)\sSIZE\s
+?=\s?(\d+)(.+?)FACE\s?=\s?('|")?([^\7]+)\7[^>]*>/genStyleCSF($3,$5,$8
+)/iegs;
$instream =~ s/<FONT(.*?)\sCOLOR\s?=\s?('|")?(\#......)\2(.*?)\sSIZE\s
+?=\s?(\d+)[^>]*>\s*/genStyleCS($3,$6)/iegs;
$instream =~ s/<FONT(.*?)\sCOLOR\s?=\s?('|")?(\#......)\2(.+?)FACE\s?=
+\s?('|")?([^\5]+)\5[^>]*>\s*/genStyleCF($3,$6)/iegs;
$instream =~ s/<FONT(.*?)\sCOLOR\s?=\s?('|")?(\#......)\2[^>]*>\s*/gen
+StyleC($3)/iegs;
$instream =~ s/<FONT(.*?)\sSIZE\s?=\s?(\d+)(.+?)FACE\s?=\s?('|")?([^\4
+]+)\4[^>]*>\s*/genStyleSF($2,$4)/iegs;
$instream =~ s/<FONT(.*?)\sSIZE\s?=\s?(\d+)[^>]*>\s*/genStyleS($2)/ieg
+s;
$instream =~ s/<FONT(.+?)FACE\s?=\s?('|")?([^\2]+)\2[^>]*>\s*/genStyle
+F($3)/iegs;

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
