Is there such a function where I could allow my dom document here append and
not have to create a new one every time when a new selection is made?
Thanks for your help.

First, I don't see where you need to append anything. Your code simply
opens XML documents that you fetch from remote sources and iterates
through the nodes in each document to echo links to the articles. If
that's all you need, what you have looks like it will work just fine.
If you are concerned about the overhead of creating a new DOMDocument
each time through the loop, you could move that step outside the loop.
Every time you run $xmlDoc-load($xml) it will replace the existing
contents with the new contents. However, I suspect that instantiating
a new object is fairly cheap compared to the rest of the actions in
your loop, so I doubt you'll save much.
As for your original question, if you really need to append multiple
XML documents into a single document using DOM, you would need to
create a DOMDocument outside the loop that contains your aggregator's
information in the header and that will contain the aggregated items.
Then inside your loop you would still load each feed into a separate
DOMDocument instance just as you are now and import the nodes from the
rss feed into your aggregated document.

RE: [PHP] Append Dom Document
Hi, You are right about the fact I am not having multiple documents, and yet what I am trying to do here is to have one xmldoc, which I have declared in my original email, and have my other rss feeds that I am trying to call from the PHP to append as I check more checkboxes from the list. Right now, when I check one box, it does present it the way I want it, which is open a new xmldoc, and print out the rss feed. Yet, when I try to check the second box, it gives me the display of the rss feed from the second and not the first, because the second one opens a new xmldoc. However, I would like to see both docs in one screen, which is why I want to know if there is such a function available. Is what I am trying to do here possibly by any chance? Thanks for your help.

Just move all of your DOMDocument code block inside the loop after the switch.
?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=NWFcm_cat=rsspar=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 (pa 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:

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?

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. umm, i dont see you making any modifications to the original document, $xmlDoc in your code. thats why i suggested simple xml, its the go-to imo if all you need to do is traverse an existing document. DOM is much better if you need to edit the document. having said that if you wanted to append a new DOMNode to an existing one, you would use the appendChild() method. Am I making sense here? no because youre not editing the DOMDocument in your code, youre just reading a document; what is getting overwritten here? im not entirely sure what youre trying to accomplish. -nathan
