It works fine as it is right now (with proper domain and page info) -
but i need to get at the only attribute of the parent in the XML
(href).
Hoping someone can help me with this one. Google / PHP forums turned
up nothing as did my PHP books.
To clarify - i need to get at the attribute within the result item.
--> <result href="http://www.icbc.com/Licensing/index.html">
--> href="http://www.icbc.com/Licensing/index.html"
I want to put it inside the "link_href" variable and display it along
with all of the other variables.
Thanks |
