Selecting the 'Current' XML Record
Posted: Wed Dec 03, 2008 5:20 am
I have php code that uses an XML file to display in an HTML page the 'Next' and 'Previous' pages for that page.
The code currently selects ALL of the XML records and then displays them on the page. What I would like to be able to do is have the HTML only display the next and previous links for the current page.
What would be the best way to do this?
Perhaps Select only where the XML Title = the HTML page title?
