Hi,
I am trying to create a news feed page that loads a number of different feeds depending on what options the user selects. For some reason, I could not figure out how to get the dom document to "append" the different xml documents that get created.
Below is the code, and obviously now every time when I try to have a new item selected, then it displays that element's
<?php
$q=$_GET["q"];
$q2 = explode(" ",$q);
$count = count($q2);
for($i=0;$i<$count;$i++) {
//find out which feed was selected
switch ($q2[$i]) {
case "Weather":
$xml=("http://rss.weather.com/rss/national/rss_nwf_rss.xml?cm_ven=NWF&cm_cat=rss&par=NWF_rss";);
break;
case "NFL":
$xml = ("http://www.nfl.com/rss/rsslanding?searchString=home";);
break;
default:
exit;
break;
}
}
$xmlDoc = new DOMDocument();
$xmlDoc->load($xml);
//get and output "<item>" elements
$x=$xmlDoc->getElementsByTagName('item');
for ($i=0; $i<=4; $i++)
{
$item_title=$x->item($i)->getElementsByTagName('title')
->item(0)->childNodes->item(0)->nodeValue;
$item_link=$x->item($i)->getElementsByTagName('link')
->item(0)->childNodes->item(0)->nodeValue;
$item_desc=$x->item($i)->getElementsByTagName('description')
->item(0)->childNodes->item(0)->nodeValue;
echo ("<p><a href='" . $item_link
. "'>" . $item_title . "</a>");
echo ("<br />");
echo ($item_desc . "</p>");
}
you might have an easier time w/ SimpleXML for this task; have a look at the examples:
http://us.php.net/manual/en/simplexml.examples-basic.php
the other thing i find strange about this code is the xml parsing assumes a similar schema when the source urls are from seemingly totally disparate domains, and topic .. id guess it sheer coincidence they have overlapping schemas at all.
I am not sure what you mean in your second point, but I can explain the first one. I am using PHP to parse RSS feeds, so that is why they all look the same. Or, what do you mean here? I checked out your example, but my problem here is that I cannot get the XML Dom document to append when I make a new selection. I am hoping that it would create a new sub document of some sort beneath the new one, instead of overwriting the entire document.
Am I making sense here?
Alice
