Hi everyone,
I am new in using the magicparser. I have an xml file of my own and i want to show random results from this file 1 or 2 or 3.
Is there a way i am able to reach this goal using magicparser. In my case i know how many feed items are there in my xml file. I have tried the following code which david have mentioned here 'http://www.magicparser.com/node/248'
<?php
// global array to hold all records
$records = array();
function myRecordHandler($record)
{
// add this record to the global array
global $records;
$records[] = $record;
}
// parse the feed to load all records
MagicParser_parse("feed.xml","myRecordHandler");
// use PHPs array_rand function to extract n random records
$random = array_rand($records,5);
foreach($random as $i)
{
$record = $records[$i];
// display $record here just as in myRecordHandler
}
?>
I modified it to this;
<?php
require("MagicParser.php");
// global array to hold all records
$records = array();
function myRecordHandler($record)
{
// add this record to the global array
global $records;
$records[] = $record;
}
// parse the feed to load all records
MagicParser_parse("http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml","myRecordHandler");
// use PHPs array_rand function to extract n random records
$random = array_rand($records,5);
foreach($random as $i)
{
$record = $records[$i];
// display $record here just as in myRecordHandler
}
?>
But it is giving me a blank page. I don't know about php programming, but i do understant a bit. Please let me know if anyone in this forum can write me the right code.
Thanks,

Hi,
There isn't actually any output code in that snippet, so you would need to add code to display the record. For example:
<?phprequire("MagicParser.php");
// global array to hold all records
$records = array();
function myRecordHandler($record)
{
// add this record to the global array
global $records;
$records[] = $record;
}
// parse the feed to load all records
MagicParser_parse("http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml","myRecordHandler");
// use PHPs array_rand function to extract n random records
$random = array_rand($records,5);
foreach($random as $i)
{
$record = $records[$i];
// display $record here just as in myRecordHandler
print "<h2>".$record["TITLE"]."</h2>";
print "<p>".$record["DESCRIPTION"]."</p>";
}
?>
Notice how at the point where I have added the print lines, you can use $record exactly as you would have done in the myRecordHandler() function. Simply change the number 5 in the following line for more or less random records...
$random = array_rand($records,5);Hope this helps!
Cheers,
David.
