Roi Dayan writes, at the [Tcl'ers Chat], a method for stripping HTML with an option to ignore specific tags:


      proc strip-html-ignore {text {ignore {}}} {
          set c 0
          foreach i $ignore {if {[regexp $i $text]} {return $text}}
          return ""
      }
       
      proc strip-html {html {ignore {}}} {
          regsub -all -- {<[^>]*>} $html "\[strip-html-ignore \[list &\] [list $ignore]\]" html
          set html [subst $html]
          return $html
      }
       
       
Syntax: strip-html text [[list ignore1 ignore2]]
       
Example:
       
      set a {<pre><a href=bla>roi<hr></a></pre><br>}
      puts [strip-html $a [list <br> <a.*>]]
       
will output:
      <a href=bla>roi<br> 


-----------------

For big values it will raise error cause of special chars problems and such :) 
for big strings (like a whole page you fetch with http package) use this:


    proc strip-html {html {ignore {}}} {
        set m {[][\;\$]}
        regsub -all $m $html \\\\& html
        foreach i $html {
            regsub -all -- {<[^>]*>} $i "\[strip-html-ignore \[list &\] [list $ignore]\]" i
            if {[catch {set i [subst $i]} tmp]} {
               puts i:$i
               puts tmp:$tmp
               break
           }
           lappend html2 $i
       }
       return $html2
    }
