PHP XML losing attributes - php

Question

i have a problem while I load xml string into SimpleXMLElement ( i tried also with DOCDocument but result is the same). In XML i have this :
<definedNames>
<definedName name="name1" Id="1" hidden="1">NAME_TEST</definedName>
<definedName name="name2" Id="4" hidden="1">NAME_TEST_2</definedName>
</definedNames>
Now i need access to specific tag using 'name' attribute. But always when i tried to print_r, var_dump or smth else i always see all other attributes, but when comes to i see only array with
[0] = > NAME_TEST,
[1] => NAME_TEST_2
I tried also xpath, but everytime when i refer to attributes inside i get empty array.
So for now i tried : xpath, SimpleXMLDom, DOCDocument but result is always the same - empty array. Any clue ?
#edit
$xl->LoadTemplate('#xl/workbook.xml');
if (isset($workbook) && is_array($workbook) && count($workbook > 0)) {
$dom = new DOMDocument();
$dom->loadXML($xl->Source);
$xpath = new DOMXpath($dom);
foreach ($xpath->evaluate('//definedName') as $definedName) {
echo $definedName->getAttribute('name');
}
} else {
$TBS->Source = preg_replace('~\<definedNames\>.*\<\/definedNames\>~', '', $TBS->Source);
}
#edit2 - xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<workbook xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="x15" xmlns:x15="http://schemas.microsoft.com/office/spreadsheetml/2010/11/main">
<definedNames>
<definedName name="name1" Id="1" hidden="1">NAME_TEST</definedName>
<definedName name="name2" Id="4" hidden="1">NAME_TEST_2</definedName>
</definedNames>
</workbook>
i know there is smth like , but i already tried :
$xpath->evaluate('//workbook/definedNames/definedName[#*]')
or
$xpath->evaluate('/workbook/definedNames/definedName[#name="name1"]')
still result is empty.

With DOMDocument, you use Xpath to fetch values or nodes.
Load the XML into a document and create an DOMXpath instance for it:
$dom = new DOMDocument();
$dom->loadXml($xml);
$xpath = new DOMXpath($dom);
Fetch a node value as string:
var_dump($xpath->evaluate('string(//definedName[#name="name1"])'));
Output:
string(9) "NAME_TEST"
Fetch all definedName element data into an array:
$byName = [];
foreach ($xpath->evaluate('//definedName') as $definedName) {
$byName[] = [
'name' => $definedName->getAttribute('name'),
'id' => $definedName->getAttribute('Id'),
'hidden' => $definedName->getAttribute('hidden'),
'text' => $definedName->nodeValue
];
}
var_dump($byName);
Output:
array(2) {
[0]=>
array(4) {
["name"]=>
string(5) "name1"
["id"]=>
string(1) "1"
["hidden"]=>
string(1) "1"
["text"]=>
string(9) "NAME_TEST"
}
[1]=>
array(4) {
["name"]=>
string(5) "name2"
["id"]=>
string(1) "4"
["hidden"]=>
string(1) "1"
["text"]=>
string(11) "NAME_TEST_2"
}
}

You can use the attributes() method on each element of the SimpleXMLElement Object. You can then access them:
$xml = '<definedNames>
<definedName name="name1" Id="1" hidden="1">NAME_TEST</definedName>
<definedName name="name2" Id="4" hidden="1">NAME_TEST_2</definedName>
</definedNames>';
$x = new SimpleXMLElement($xml);
foreach ($x as $element) {
var_dump($element->attributes());
}
The above returns:
object(SimpleXMLElement)#4 (1) {
["#attributes"]=>
array(3) {
["name"]=>
string(5) "name1"
["Id"]=>
string(1) "1"
["hidden"]=>
string(1) "1"
}
}
object(SimpleXMLElement)#3 (1) {
["#attributes"]=>
array(3) {
["name"]=>
string(5) "name2"
["Id"]=>
string(1) "4"
["hidden"]=>
string(1) "1"
}
}
You can then access individual attributes by using in the loop:
foreach ($x as $element) {
$element->attributes()->hidden;
$element->attributes()->Id;
$element->attributes()->name;
}

try simplexml_load_string()
$p = '<definedNames>
<definedName name="name1" Id="1" hidden="1">NAME_TEST</definedName>
<definedName name="name2" Id="4" hidden="1">NAME_TEST_2</definedName>
</definedNames>';
$xml = simplexml_load_string($p);
echo $xml->definedName[0]->attributes()->name;
echo $xml->definedName[1]->attributes()->name;
or use foreach to get all attaributes
