[phpXML] Searching on attributes

[<lu...@sa...>]

Hello,

Sorry guys its time to fire the my_stupid_question_of_the_day() function :


In the government example, the search function is pretty simple because the 
search is done on content
             if ( !empty($term) )
             {
                 // Only select those persons, in whose name or position
                 // the search string is present.
                 $government = $xml->evaluate(
                     "//person/*[contains(., $term)]/..");
             }
             else
             {
                 // Select all members of the government.
                 $government = $xml->evaluate("//person");
             }

How would one (one = me) proceed to do the same kind of thing with a search 
based on attributes
especially as attributes aren't accessed directly but through an array

In fact I've a file that is an agenda and I'd like to be able to search on 
the attribute month "name" :

<agenda>
	<month name="January">
		<event>
			<date/>
			<location>
				<name/>
				<address/>
				<town/>
				<country/>
			</location>
			<phone/>
			<email/>
			<web/>
			<description/>
		</event>
	</month>

Thanks in advance

Luc

As is described (aka RTFM ;-) in the ZVON tutorial 
http://www.zvon.org/xxl/XPathTutorial/General/examples.html


  //month[@name='January']

Tom

I read the FM several times ;-))
I tried
if ( !empty($month_name) )
             {
         $sorties = $xml->evaluate('//agenda/month[@name="$month_name"]');
             }
             else
             {
                $sorties = $xml->evaluate('//agenda/month');
             }
If I use this I get a

phpXML error: While parsing the XPath expression "$month_name" an empty and 
therefore invalid node-test has been found.

The FM doesn't say what does "an empty and therefore invalid node-test has 
been found" mean in plain english ;-))

Bonjour luc,

Le samedi 7 juillet 2001 à 09:10:32, vous écriviez :

lsec> '//agenda/month[@name="$month_name"]');

It's not phpXml but an error with your PHP coding :
Between single quotes PHP doesn't calculate/evaluate the variables if
you make this test :
$month_name = 18;
echo '//agenda/month[@name="$month_name"]';

You will obtain this output :  //agenda/month[@name="$month_name"]

To correct you must write :
echo "//agenda/month[@name=\"$month_name\"]";
and you will have : //agenda/month[@name="18"]

I prefer this :
echo sprintf( '//agenda/month[@name="%s"]', $month_name) ;

I use echo to demonstrate, you use this in strings..
(Sorry but my english is poor, I hope I help you)

Daniel,

This is much more efficient FM ;-)
Thanks a lot

by the way fore some reason

$sorties =3D $xml->evaluate('//agenda/month[@name=3D"%s"]', $month_name);

give an empty array

while
$sorties =3D $xml->evaluate('//agenda/month[@name=3D'.$month_name.']');

works OK

Thanks again

Luc

Yes, IPT provides PHP4.0.6 with sablot 0.60
What do you want exactly.
Use this private adress :
