Hi Everyone.
I am having trouble figuring out how to remove a string from a text file.  If someone could help I would really appreciate it.  Below is a css that I have and I need to remove the "position:relative" from each of the "a" tags and leave the rest alone.

input {
      position:relative;
}

iframe {
      position:relative;
}
button {
      position:relative;
}

a { color: white;
      font-size: 12px;
      font-weight: bold;
      text-decoration: none;
      position:relative;
}

a:hover { color: silver !important;
      font-size: 12px;
      font-weight: bold;
      text-decoration: none;
      position:relative;
}
a.category {
      font-family: Verdana, Arial, Helvetica, sans-serif;
      color: silver;
      font-size: 16px;
      font-weight: bold;
      position:relative;
}

a.category:hover {
      color: #8e8e8e !important;
      font-family: Verdana, Arial, Helvetica, sans-serif;
      font-size: 16px;
      font-weight: bold;
      position:relative;
}

I'm in a hurry for this so I am giving maximum points.
Thanks

Hi ozo,
Thanks for the response.  I am trying to modify a string that I already have loaded and done a few other things to.  I also need the "position:relative;" replaced on each of the tags related to "a" such as "a.category:hover", "a.category", "a:hover".  One problem I have is they may or may not be there or there may be new ones.  I just need to make sure that all "position:relative;" with a preceeding "a" gets removed.  Now since I have a terrible time figuring out regexp's, will what you gave me handle this?

my $style = "...the text listed above..."

Thanks again.
