XML: child node

[nuttynibbles]

XML:

<Category name="Books">
        <Item fieldname="Author" datatype="string" value="AAA" />
        <Item fieldname="ISBN" datatype="string" value="BBB" />
        <Item fieldname="Publisher" datatype="string" value="CCC" />
      </Category>

how can i use child node to extract the value of fieldname author = AAA
fieldname ISBN = BBB
....

Use [man]simplexml_load_string/man to load the data as a [man]SimpleXMLElement[/man] object.

If you're unsure of how to use the object, easiest way to learn its structure is to do a [man]var_dump/man of it.

i would like to use domdocument. is that a way for it??

if im not wrong, i have to first select getElementsByTagName() then use childNodes??

$elem = $xmlDoc->getElementsByTagName('Entity')->item(0);
$children = $elem->childNodes;
foreach ($children as $child) {
echo $child->getAttribute('Item'); //im not getting any result here
}

but im not getting any result..

There is no attribute 'Item'.

'Item' is the name of the node.

Try, getAttribute('value')

I think the SimpleXML library is way easier to work with...

Hey JohnPeace,

it works. Tks dude.

i was actually working using another method but it wasn't looping through the 2nd and 3rd row:

$elem = $xmlDoc->getElementsByTagName("Category");
    $i = 0;
      foreach($elem as $x){
        if($x->getElementsByTagName('Item')->item($i)->getAttribute('fieldname')=="Author")
          echo "Author: ".$x->getElementsByTagName('Item')->item($i)->getAttribute('value')."<br />";
        if($x->getElementsByTagName('Item')->item($i)->getAttribute('fieldname')=="ISBN")
          echo "ISBN: ".$x->getElementsByTagName('Item')->item($i)->getAttribute('value')."<br />";
        if($x->getElementsByTagName('Item')->item($i)->getAttribute('fieldname')=="Publisher")
          echo "Publisher: ".$x->getElementsByTagName('Item')->item($i)->getAttribute('value')."<br />";

    $i++;
  }

any idea why?? for curiosity sake =)
