Hi is it possible to replace some html lines, that don't have any special id/name.

example:


<tr><td style="height: 10px;">nice <a href="http://www.google.com" target="_blank">link</a></td></tr>

to:


<tr><td style="height: 10px; display:none;">nice <a href="http://www.google.com" target="_blank">link</a></td></tr>

using php str replace or any other way?

thanks

You would definitely need a regular expression. I'm no expert, but here's a RegEx tutorial: http://www.regular-expressions.info/tutorial.html

You would have to use preg_replace()

I'm no expert either, but if you found some special "class" or "ID" for a parent item, then you could do it with nested CSS... It's messy, but it would work.


something like this...



<style type="text/css">
.parent_item_class{
margin:0px;
}
.parent_item_class table tr td td td tr td{
display:none;
}

Well it's also possible with JavaScript I suppose. Not server-side, but oh well:


<script type="text/javascript">
window.onload = function() {
var td = document.getElementsByTagName("TD");
for (var i = td["length"]-1;i > -1;--i) {
if ((td[i]["id"])["length"] < 1) {
td[i]["style"]["display"] = "none";
};
};
};
</script>

Or maybe something like htmlSQL (http://www.jonasjohn.de/lab/htmlsql.htm).

};
};
};
</script>

But wouldn't that set ALL <td> tags to "display:none;"?

It will set the display to none if the TD didn't have an ID tag:


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title></title>
<script type="text/javascript">
window.onload = function() {
var td = document.getElementsByTagName("TD");
for (var i = td["length"]-1;i > -1;--i) {
if ((td[i]["id"])["length"] < 1) {
td[i]["style"]["display"] = "none";
};
};
};
</script>
</head>
<body>
<table>
<tr>
<td>test</td>
<td id="foo">asd</td>
<td id="foo1">asd</td>
<td id="foo2">asd</td>
</tr>
</table>
</body>
</html>

<tr>

<td id="foo">asd</td>
<td id="foo1">asd</td>
<td id="foo2">asd</td>
</tr>
</table>
</body>
</html>

Ah, but what if the <td> was a "class='whatever'"?

wouldn't you need to add something like:



if ((td[i]["class"])["length"] < 1)
