very simple eregi / loop question

How would you loop though a file ( or web page) and get all of a certain thing. I'm trying to strip stuff out of tables, but I have only managed to get the first of what I'm searching for. My expression is eregi("[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}", $search, $content); which does the job, but how do I apply that to get all of that from the page? thanks -- ------------------------------------------------------------ Robert Packer Programming and Design Associate 814-944-1108 robert@nrc.net -- NRC Online -- ------------------------------------------------------------
