php,dom, xml

Helliio,


I have a xml file that has 106 books.
Each book has an id.
Every time that a user selects a writer from suggestions, I would like to present the id's of the books that he wrote on my page.


$w has the name of a writer that user selects

$w = $_GET['node'];

At my xml file writers have that xpath:

/ead/archdesc/dsc/c01/bibliography/bibref

and the id's of every book:

/ead/archdesc/dsc/c01/did/unitid

Any ideas?

thnx in advance :)

the principle is simple. in the XPath, set a condition whose value is fed by a variable/parameter.

what you need is a relation between the writer and the book id (in the XML). without that it’s near impossible to get the matches.
