Httprequest To Extract The Tag To Get The Full Link?

I am working on httpwebrequest method to read the php page from my site. What I am trying to do is to read the php page while read the html tags for each line, find the matched string that I have selected on the listview, then extract and get the full link of the tag called "delete" and then displaying the messagebox. Something would be like this:

[URL]

At the moment, I find it a bit difficult job to work it out on myself to get the right tag as each of them have got the same ids. The id I wish to extract from the page and get the full link is called delete. Something is like this:

<p id="delete"> <a href="delete.php?id=ANYNUMBER1">Delete</a></td><p id="delete"> <a href="delete.php?id=ANYNUMBER2">Delete</a></td>

Here's the php page

Hello
Delete

Whatever the strings goes

Delete

If you know how I can extract each of the tag to get the delete link with the correct id while read the php page and get the matched listview item that I selected.
