Get data from XML with PHP - php

Question

below is part of my XML where I try to get data from, basicly I need to insert them to array where "role" is key and "entry" is value.
Here is XML:
<CommunicationDetailList>
<CommunicationDetail>
<Role>Phone1</Role>
<Entry>727831333</Entry>
</CommunicationDetail>
<CommunicationDetail>
<Role>Mobile</Role>
<Entry>727834125</Entry>
</CommunicationDetail>
<CommunicationDetail>
<Role>Fax1</Role>
<Entry>123456789</Entry>
</CommunicationDetail>
<CommunicationDetail>
<Role>EMail1</Role>
<Entry>moj#mail.sk</Entry>
</CommunicationDetail>
</CommunicationDetailList>
This is my PHP code, unfotunately it doesn't work correctly (add just first one not rest of it, so I have access just to Phone1):
//this is somewhere on top of my code
$doc = new DOMDocument();
//Load XML to DOM
$doc->loadXml($xml);
.
.
// here I parse rest of XML, where `<tags>` are unique
.
.
//and here is that important part
$communicationDetails = $doc->getElementsByTagName( "CommunicationDetailList" );
foreach( $communicationDetails as $detail )
{
$keys = $detail->getElementsByTagName( "Role" );
$key = $keys->item(0)->nodeValue;
$values = $detail->getElementsByTagName( "Entry" );
$value = $values->item(0)->nodeValue;
//adding login and password to array
$data[$key] = $value;
}
Can someone help me to access to this XML

Answer 1

Try using SimpleXMLElement like this
<?php
$xml = 'data.xml';
//load xml from file
$doc = simplexml_load_file($xml);
// or load from string
// $doc = simplexml_load_string($xmlString);
foreach($doc->CommunicationDetail as $detail){
//print $detail->Role . ' - ' . $detail->Entry . PHP_EOL;
$data[(string)$detail->Role] = (string)$detail->Entry;
// we cast the xml elements as strings to be used as keys and values in the array
}
print_r($data);
//output is
Array
(
[Phone1] => 727831333
[Mobile] => 727834125
[Fax1] => 123456789
[EMail1] => moj#mail.sk
)

Try this may be it help
foreach( $communicationDetails as $detail )
{
$keys = $detail->getElementsByTagName( "Role" );
$values = $detail->getElementsByTagName( "Entry" );
$length = $keys->length;
for($i = 0; $i <= $length; $i++)
{
$key = $keys->item($i)->nodeValue;
$value = $values->item($i)->nodeValue;
$data[$key] = $value;
}
}

The problem is with
$item(0)
If you were to use a iterated loop like
for ($i=0; $i<count($keys); $i++) { echo $keys[$i]; }
Then it would go through the entire array.
