I have been strugglign with this function.

It says that str.replace is not a function, any ideas why?

The function is suppose to strip tags (<something></something>) from the input.

[CODE]function st(ip)
{
var str = ip;
return str.replace(/<(.*)>/g,””);
}[/CODE]

Thanks!
Chris

I'm not getting that error.

BUT, and I'm guessing, you will not get what you expect.

I think this is what you want.
<i>
</i>var text = "&lt;tag&gt;word&lt;/tag&gt;";
var data = st(text);
alert(data)

function st(ip) {
var str = ip;
return str.replace(/&lt;.*?&gt;/g,"");
}

@aximbigfanauthorApr 06.2008 — Any ideas how I could extract the value of what is between the tags?

Thanks!

<i>
</i>function st(ip) {
var str = ip;
return str.replace(/&lt;.*?&gt;/g,"&lt;&gt;");
}

Ops! Not what you asked for. I'll be back

If you have just one tag in ip, it's easy.
<i>
</i>return str.replace(/&lt;(.*)?&gt;/g,"$1");

If you have multiple tags it's a lot more tricky.

Parsing HTML is not the easiest thing to do.

This will extract the tag name of only the first tag in a line.
<i>
</i>var text = "some text followed by a &lt;tag&gt;word&lt;/tag&gt;and more text";
var data = st(text);
alert(data)

function st(ip) {
var str = ip;
return str.replace(/^.*?&lt;(.*?)&gt;.+$/,"$1");
}

If you have multiple or nested tags, it can get really complicated.

Nothing nested, no, basically what it is is that I am going for a sort of XMLish format. Anyway, I got it working, thanks!!
