Replace HTML tag property

[Anon]

How can I replace this:
<a href="111"><img src="222"></a><a href="111">333</a>444<a href="111"></a> <a href="555"><img src="666">777<a href="555"></a>888

with this:
<span class="..."><a href="111"><img src="222"></a><a href="111">333</a>
<span class="..."><a href="555"><img src="666"></a><a href="555">777</a>

I know it's confusing :o

Where is the problem exactly ? You want the replacement done with PHP ?

it's string manipulation, in a loop like :

$html='';

for i=0 to MaxNum
$html .= "<span class ..."
$html .= <a href= ..."
...
next i

No ?

🙁 No what I wanted is how to replace file content looks like this:
$olddata='<a href="art.htm"><img src="moon.gif"></a><a href="art.htm">My Show Room</a> It contains my stuff (no link text).. <a href="art.htm">more</a> <a href="work.htm"><img src="drve.jpg">My Work is a buss driver</a> who drives a buss (no link)<a href="work.htm">more</a>.. ';

with this:
$newdata='<span class="imgShade"><a href="art.htm"><img src="moon.gif"></a></span><a href="art.htm">My Show Room</a>
<a href="work.htm"><span class="imgShade"><img src="drve.jpg"></a></span><a href="work.htm">My Work is a buss driver</a>.. ';
