How to extract value from ?

I have a grid whose rows like this one :

<textarea name="ctl00$ContentPlaceHolder1$DataGrid0$ctl02$TxtValueDesc" rows="2" cols="20" id="ctl00_ContentPlaceHolder1_DataGrid0_ctl02_TxtValueDesc" class="TextBox" RowNo="0" style="font-size:8pt;width:350px;">PT. WINDU EKA</textarea>

I want to extract string PT. WINDU EKA by using ctl00$ContentPlaceHolder1$DataGrid0$ctl02$TxtValueDesc as search key, but I have no idea how to construct regex to extract it.
Thx in advance.
