Parse XML to HTML with PHP SimpleXMLElement - php

Question

I am having some issues with SimpleXMLElement that I was hoping to get some help.
I was reading about SimpleXMLElement and I built a PHP page to parse this XML:
<?xml version='1.0'?>
<AdXML>
<Response>
<Campaign>
<Overview>
<Name>strip</Name>
<Description>category</Description>
<Status>L</Status>
</Overview>
<Pages>
<Url>page01</Url>
<Url>page02</Url>
<Url>page03</Url>
</Pages>
</Campaign>
</Response>
</AdXML>
Tag "Pages" can have any number of tags "Url" other tags might have only one value, like the tag "Name" for example.
Reading about SimpleXMLElement I ended up with the following code:
$xmlparsed = new SimpleXMLElement($xml); //my xml is being sent as variable
To display single values I am using the code below without a problem:
<?php echo $xmlparsed->Response[0]->Campaign[0]->Overview[0]->Name;?>
Everything works fine. But when I try to parse a tag with multiple lines I get only one line, and everytime I refresh the page it gives me a different "url" value. This is the code I am using:
<?php foreach ($xmlparsed->Response->Campaign->Pages as $Pages) {echo $Pages->Url, PHP_EOL;} ?>
According to PHP's site: http://php.net/manual/en/simplexml.examples-basic.php this should work, but it isn't.
Since I am not expert on PHP I am testing code on a trial-and-error basis.
What am I doing wrong here?
thanks in advance for any help.

Answer 1

You only have one Pages so you are only entering that foreach once. Try looping on the urls.
$xml = "<?xml version='1.0'?>
<AdXML>
<Response>
<Campaign>
<Overview>
<Name>strip</Name>
<Description>category</Description>
<Status>L</Status>
</Overview>
<Pages>
<Url>page01</Url>
<Url>page02</Url>
<Url>page03</Url>
</Pages>
</Campaign>
</Response>
</AdXML>";
$xmlparsed = new SimpleXMLElement($xml);
foreach ($xmlparsed->Response->Campaign->Pages->Url as $url) {
echo $url, PHP_EOL;
}
Output:
page01
page02
page03

You can also use XPath.
foreach( $xml->xpath( 'Response/Campaign/Pages/Url' ) as $url ) {
echo $url;
}
