Getting a whole xml node

[watsmyname]

Hello

I have xml like this.

<?xml version="1.0" encoding="utf-8"?>
<data>
   <item ID="30001">
      <Company>Navarro Corp.</Company>
   </item>
   <item ID="30002">
      <Company>Performant Systems</Company>
   </item>
   <item ID="30003">
      <Company>Digital Showcase</Company>
   </item>
</data>

 

All i need to do is get any one of the  whole node from starting item tag to ending item tag from the xml, for example.  getting

<item ID="30002">
      <Company>Performant Systems</Company> 
   </item>

from whole xml file.

 

Can this be achieved using  SimpleXML object from PHP? if not how it can be done.

 

 

Thanks in advance

Do you want to return the XML as a SimpleXMLElement object, or just as a string?

$str = '<?xml version="1.0" encoding="utf-8"?>
<data>
   <item ID="30001">
      <Company>Navarro Corp.</Company>
   </item>
   <item ID="30002">
      <Company>Performant Systems</Company>
   </item>
   <item ID="30003">
      <Company>Digital Showcase</Company>
   </item>
</data>';

$xml = new SimpleXMLElement($str);
foreach ($xml->children() as $node)
{
    // right now $node contains the SimpleXMLElement
    // but you can return it as a string with ->asXML()
    echo $node->asXML();
}

$str = '<?xml version="1.0" encoding="utf-8"?>
<data>
   <item ID="30001">
      <Company>Navarro Corp.</Company>
   </item>
   <item ID="30002">
      <Company>Performant Systems</Company>
   </item>
   <item ID="30003">
      <Company>Digital Showcase</Company>
   </item>
</data>';

$xml = new SimpleXMLElement($str);
foreach ($xml->children() as $node)
{
    // right now $node contains the SimpleXMLElement
    // but you can return it as a string with ->asXML()
    echo $node->asXML();
}

well thanks for the reply but your code returns  " Navarro Corp.  Performant Systems  Digital Showcase  "

i want whole

 <item ID="30001">
      <Company>Navarro Corp.</Company>
   </item>

out of the given xml string, i.e.

including Item start tag to item end tag

That's because the browser's trying to render it as HTML, view the source.

Thanks, you're right!

I used htmlentities to get tag as well

echo htmlentities($node->asXML());

 

Thanks a ton

Well,

I have having a problem now. If a given xml has node

<Company>Navarro Corp.</Company>

  There is no problem asXML returns as it is.

But if it has

<company></company>

It returns <company/> only i want it to return <company></company>

I'm not sure to be honest. ->asXML() doesn't have any formatting options so I'm not sure you'll be able to. They do mean the same thing though, why do you need it changing?

well the matter of fact is that a code reads an xml file, and each node is listed in each row of the  table through loop. and each time it puts a equivalent node in hidden text area. So first time in text area it puts

<item ID="30001">
      <Company>Navarro Corp.</Company>
   </item>

Second time it loops, in another text area it puts

<item ID="30002">
      <Company>Performant Systems</Company>
   </item>

and so on.  Actually this is done to delete a particular node. There is delete button in the last column of each row. When it is clicked, The value of corresponding text area is posted to next page. In next page again whole previous xml file is loaded as string. We match the value of text area to this string and replace it with blank space. and resulting string is saved as xml again.

Why don't you just pass the item ID and remove the node using SimpleXML?

Why don't you just pass the item ID and remove the node using SimpleXML?

The given xml is just an example. There might be many tags with many attributes, and the amount of attributes on each node will be different and so are their values.

OKAY I SOLVED IT.  BUT IN A BIT LONG way.

I'll be honest, it sounds like there should be a better way to do it. Perhaps you'd need to use the DOM for more advanced functionality?

I used fread function to read an xml file. I put content in a string. I then exploded the string with </company>. I get each opening company tags with attributes in an array, i looped it and put each value [then concated </company> in array element] in the text area. And the text area is posted to another page. Rest i have already told.
