Count amount off HTMLTags in a textarea value 1

[RayDance]

I'm inserting large amounts off text in one textarea and it's HTML text. I use <hr /> for a page break, but now I want to know how many pages I have in one textarea. So I have to know the amount/count off the <hr /> TAGs. Does anybody know how I can count these <hr /> TAGs from the texarea value? Maby something with getElementsByTagName??

Now I have something like this:
* myform.ItemInfo is a textarea

<script>
arrayOfHRs = document.myform.ItemInfo.getElementsByTagName(&quot;hr&quot;
</script>

But This doesn't work.
If you can help me.... thx!

You should do it &quot;manually&quot; in a loop that search for <hr /> substring.
Use this:
if (myform.ItemInfo.value.indexOf(&quot;<hr />&quot != -1)
counter ++

An easier way out is to do this:

arrayOfPages=document.myForm.ItemInfo.value.split('<hr />');
alert(arrayOfPages.length)

You won't exactly retain the <hr /> tags, but you'll have a quick and easy way to find the number of pages and reference each one without much difficulty.
