Convert anything between tags

phprock

I have a html file which has lots of html tag. I want to change character between these tags only by applying a function (ie. french($textbetweentags).)

<font class="phpbuilder"> </font>

Here goes my text. <font class="phpbuilder">
this is special and convert to  something
</font>

<font class="title">Some title goes here, no need to worry about this text
</font>
Blah blah... Blah.. 
<font class="phpbuilder"> This is another text and  need to convert></font>

Here's the function I wrote for finding multiple occurences of texts:

function FindTextBetween($start_phrase,$end_phrase,$input)
{
$start_phrase = preg_quote($start_phrase,"|");
$end_phrase = preg_quote($end_phrase,"|");

$regex = "|$start_phrase(.*)$end_phrase|Us";
preg_match_all($regex,$input,$matches);
if (is_array($matches[1]))
   return $matches[1];
else return array();
}

//as for your example
$results = FindTextBetween('<font class="phpbuilder">','</font>',$input_text);
//then for each result use strreplace to convert your text.

Thank you for the function

But why does it removes other tags

$news=<font class="cool">Text</font>
 <b>Hi, this is another text with bold style</b>

$text =FindTextBetween('<font class="cool">','</font>',$news);
$desc="";
foreach($text as $value){
	$desc.=changeChar($value);
}

let say changechar funtion convert "Text" to "PSD"

So final output I would like to have is

<font class="cool">PSD</font>
<b>Hi, this is another text with bold style</b>

You can see i have changed only whatever in the cool tag

You've misunderstood me. The function was to help you to write your own, like this (I haven't checked it for errors):

function MyReplacement($input_text)
{
 $results = FindTextBetween('<font  class="phpbuilder">','</font>',$input_text);
 foreach ($results as  $res)
 {
      $input_text = str_replace($res,'<font  class="phpbuilder">what to change it to </font>', $input_text);         

 }
 return $input_text;
}

//And a slight change to FindTextBetween() to return results with start and end texts
function FindTextBetween($start_phrase,$end_phrase,$input)
{
$start_phrase = preg_quote($start_phrase,"|");
$end_phrase = preg_quote($end_phrase,"|");

$regex = "|$start_phrase(.*)$end_phrase|Us";
preg_match_all($regex,$input,$matches);
if (is_array($matches[0]))
   return $matches[0];
else return array();
}

Change this example to suit your needs.

As u are good in regular expression you might help me in this code

$news="<font class=\"cool\">Text</font>
 <b>Hi, this is another text with bold style</b>
 <a href=\"http://www.google.com\"><font class=cool>Text</font></a>
 "; 		


$test=changeChar('<font  class="cool">','</font>',$news);

Out put

$output="<font class=\"cool\">SDS</font>
 <b>Hi, this is another text with bold style</b>
 <a href=\"http://www.google.com\"><font class=cool>SDS</font></a";

Testing code


function changeChar($start="",$end="",$str){
	//Rule
	//Never ever convert any html tag 
	//if $start and $end  is empty covert all character,mass convert
	//If specified $startphrase and endphrase then convert all character between them.


$array=array(

'T'=>'s',
'x='='D',
't'='S');
//More will be added

$final="";
$data = preg_split('#(<\/?)(\w+)([^>]*>)#mis',$str);
preg_match_all('#(<\/?)(\w+)([^>]*>)#mis',$str,$matches);
$temp = array();
foreach($data as $text){
$temp[] = strtr($text,$array);
}
for($i=0;$i<sizeof($temp);$i++){
$final .= $temp[$i].$matches[0][$i];
}

}

I think its better then old style.

Sorry for taking your time. Your help would be very helpfull.

I'm not that good with regex. I can think of a way to do the task you want to do using my function, but not in a very clean, simple and efficient way.

Sorry
