Hi Folks,
I was looking through the CVS example for the XML_Parser class
and was looking for something just a little more complicated. While I've
had lots of experiencing generating XML, applying stylesheet transformations
to them, I am still new to the whole parsing game.
A sample xml code fragment:
<georeference>
<continent id="North America">
<country id="Canada">
<region id="AB">
<site id="AB-12">
<name>Airdrie</name>
</side>
</region>
</country>
</continent>
</georeference>
I was looking to roll up and provide a list of the entire name & site id
combinations for a particular reigon.
Example: All of the "AB-12" & "Airdie" combinations for the province of
"AB".
I thought this might be best done by setting the mode to "func" and created
the xmltag_region() and xmltag_site() functions.
Here's my php code snippet:
<?php
/**
* Weather xml parser class used for parsing the Environment Canada
weather
* xml file
*
* @author Stephen March <steve@enerds.ca>
* @file weather.class.php, v1.0 2005/05/02
* @package Weather
**/
require_once "XML/Parser.php";
class Weather extends XML_Parser
{
/**
* Call the Superclass constructor
**/
function Weather()
{
parent::XML_Parser();
}
/**
* Function for the SITE tag. Retrieve the site name as well as the
code
**/
function xmltag_site($xp, $name, $attribs)
{
print $attribs["ID"] . "<br/>";
}
/**
* Function for the REGION tag. Retrieve the region name and all city
codes
* for the region
**/
function xmltag_region($xp, $name, $attribs)
{
print $attribs["ID"] . "<br/>";
}
}
/**
* Example useage of the Weather class
**/
$w = &new Weather();
$w->setMode('func');
$result = $w->setInputFile("canada_e.xml");
if($w->parse())
{
print "Successfully parsed!";
}
else
{
print "Could not parse file!";
}
?>
