I am having problems using the & in xml strings created by php's SimpleXMLElement. For example the following:
<?php
$xml = new SimpleXMLElement("<?xml version='1.0' encoding='UTF-8'?><links></links>");
$xml->addChild("url","https://www.somewhere.com?a=1&b=2");
echo $xml->asXML();
?>
gives me when run:
<?xml version="1.0" encoding="UTF-8"?>
<links><url>https://www.somewhere.com?a=1</url></links>
I have already tried:
...
$xml->addChild("url","https://www.somewhere.com?a=1&b=2");
...
and got:
...
<links><url>https://www.somewhere.com?a=1&b=2</url></links>
how do I get:
...
<links><url>https://www.somewhere.com?a=1&b=2</url></links>
You can't. That is illegal XML: the & character must be escaped (XML specification).

This is XML file.
<?xml version="1.0" encoding="utf-8"?>
<UW xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://tempuri.org/XMLSchema.xsd">
<UWdata>
<List>
<IdProduct>1</IdProduct>
<ProductName>product</ProductName>
<ProductNameDE>product</ProductNameDE>
<ProductNameEN>product</ProductNameEN>
<Uf>1</Uf>
<PSIg>1</PSIg>
<Ug>1</Ug>
</List>
</UWdata>
</UW>
$lines_array=file($url);
$lines_string=implode('',$lines_array);
$xml=simplexml_load_string($lines_string) or die("Error: Cannot create object");
I try with this
echo $xml->UWdata[1]->ProductName;
But it doesn't return anything.I want to return Product name.
Sample code, Use simplexml_load_string
<?php
$a = '<?xml version="1.0" encoding="utf-8"?>
<UW xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://tempuri.org/XMLSchema.xsd">
<UWdata>
<List>
<IdProduct>1</IdProduct>
<ProductName>product</ProductName>
<ProductNameDE>product</ProductNameDE>
<ProductNameEN>product</ProductNameEN>
<Uf>1</Uf>
<PSIg>1</PSIg>
<Ug>1</Ug>
</List>
</UWdata>
</UW>';
$xml=simplexml_load_string($a) or die("Error: Cannot create object");
echo ($xml->UWdata->List->ProductName);
?>
When you load the xml file using the php simplexml_load_file function to a variable. The veritable becomes an object.
<?php
$xml=simplexml_load_file("/path/to/the/file.xml");
?>
So, in your case, the $xml variable becomes a multi-level object where every elements of xml file are key of the object. Like: UWdata.
So, as $xml is a multi-level object, to access the element under UWdata, under List under ProductName, you have to code like bellow.
echo $xml->UWdata->List->ProductName."<br>";
Here,
UWdata is the key of $xml object.
List is the key of UWdata.
ProductName is the key of List.
Finally, you will get the value of key element ProductName = product
I modified your script and put the xml in an external file called testxml.xml, as it should be. Always separate the function and the data it's supposed to handle. I used your xml like this:
<?xml version="1.0" encoding="utf-8"?>
<UW xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://tempuri.org/XMLSchema.xsd">
<UWdata>
<List>
<IdProduct>1</IdProduct>
<ProductName>productTEST</ProductName>
<ProductNameDE>product</ProductNameDE>
<ProductNameEN>product</ProductNameEN>
<Uf>1</Uf>
<PSIg>1</PSIg>
<Ug>1</Ug>
</List>
</UWdata>
</UW>
And with the following script it returns productTEST only.
$xmlstr = file_get_contents('./testxml.xml');
$xml = simplexml_load_string($xmlstr);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
echo $array['UWdata']['List']['ProductName'];
Hope this helps.
//edit:
While I do not know your project, you might want to take a foreach-approach if it is possible for your xml to contain more than one List element
I'm working with SimpleXMLElement for the first time and need to generate a line in my XML as follows:
<Product xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
I haven't used addAttribute with namespaces before and can't get the correct syntax working here - I've started with this:
$node = new SimpleXMLElement('< Product ></Product >');
$node->addAttribute("xmlns:", "xsd:", 'http://www.w3.org/2001/XMLSchema-instance');
but can't work out how to correct this for the appropriate syntax to generate the desired output?
solution 1: add a prefix to the prefix
<?php
$node = new SimpleXMLElement('<Product/>');
$node->addAttribute("xmlns:xmlns:xsi", 'http://www.w3.org/2001/XMLSchema-instance');
$node->addAttribute("xmlns:xmlns:xsd", 'http://www.w3.org/2001/XMLSchema');
echo $node->asXML();
output:
<?xml version="1.0"?>
<Product xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"/>
note: this is a workaround and actually doesn't set the namespace for the attribute, but just quite enough if you are going to echo / save to file the result
solution 2: put namespace directly in the SimpleXMLElement constructor
<?php
$node = new SimpleXMLElement('<Product xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"/>');
echo $node->asXML();
output is the same as in solution 1
solution 3 (adds additional attribute)
<?php
$node = new SimpleXMLElement('<Product/>');
$node->addAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance", "xmlns");
$node->addAttribute("xmlns:xsd", 'http://www.w3.org/2001/XMLSchema', "xmlns");
echo $node->asXML();
output adds additional xmlns:xmlns="xmlns"
<?xml version="1.0"?>
<Product xmlns:xmlns="xmlns" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"/>
I am trying to convert the following line to a string using
$xml_post_string = '<?xml version="1.0" encoding="UTF-8"?>';
However, echo $xml_post_string does not print anything, but when i remove the <? from the string, it works. How can I get through this issue?
You can use html tag <xmp> for that purpose, it renders a container content "as is". But I must note that it's included in the list of "obsolete" elements.
$xml_post_string = '<?xml version="1.0" encoding="UTF-8"?>';
echo "<xmp>".($xml_post_string)."</xmp>";
// the output:
<?xml version="1.0" encoding="UTF-8"?>
I'm building xml with the SimpleXMLElement Object from PHP.
While doing so I encountered the following problem, which i can't solve:
I'm generating the root xml element like this:
$xml = new SimpleXMLElement("<?xml version=\"1.0\" encoding=\"utf-8\" ?>");
But i get a 2 XML headers when i do echo $xml->asXML(); like this:
<?xml version="1.0"?>
<xml version="1.0" encoding="UTF-8"></xml>
Which is obvioulsy wrong. But how can i fix this so i only get the
<xml version="1.0" encoding="UTF-8">
part?
You must also supply the surrounding tag.
For example:
$xml = new SimpleXMLElement('<?xml version="1.0" encoding="utf-8" ?> <BASETAG />');
I’m setting up a PHP site which will gather information from a Dell iDRAC. I want to use the returned information to create a PHP object. The information returned from the first part of the script looks like this.

When I try to use the simplexml_load_string function, it returns the following errors and does not process the data as a string.

XML;
It works like a charm. So, my question is simple. How can I tell PHP to process the string the same way it processes the XML like it does if the XML identifier is used. I have tried to reprocess the string like this:
$new_string = <<<XML
$string
XML;
But no go. Any other ideas?
Are you using file_get_contents to actually load the XML file into a string before using simplexml_load_string which—as the name states—loads XML from a string?
$xml_file = file_get_contents('test.xml');
$xml = simplexml_load_string($xml_file);
echo '<pre>';
print_r($xml);
echo '</pre>';
And the output is good when I use the XML from your post:
SimpleXMLElement Object
(
[#attributes] => Array
(
[xmlnwsa] => http://schemas.xmlsoap.org/ws/2004/08/addressing
[xmlnwsen] => http://schemas.xmlsoap.org/ws/2004/09/enumeration
[xmlnn1] => http://schemas.dell.com/wbem/wscim/1/cim-schema/2/DCIM_SystemView
[xmlnxsi] => http://www.w3.org/2001/XMLSchema-instance
)
And so on…
And so on…
And so on…
But that said, I can recreate your error exactly if I add a space or line to the beginning of the XML file like this; note the one simple space before <?xml version="1.0" encoding="UTF-8"?>:
<?xml version="1.0" encoding="UTF-8"?>
<Envelope xmlns="http://www.w3.org/2003/05/soap-envelope" xmlnwsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlnwsen="http://schemas.xmlsoap.org/ws/2004/09/enumeration" xmlnn1="http://schemas.dell.com/wbem/wscim/1/cim-schema/2/DCIM_SystemView" xmlnxsi="http://www.w3.org/2001/XMLSchema-instance">
And so on…
And so on…
And so on…
And here is my error:
Warning: simplexml_load_string(): Entity: line 1: parser error : XML declaration allowed only at the start of the document in /Applications/MAMP/htdocs/test.php on line 5
Warning: simplexml_load_string(): in /Applications/MAMP/htdocs/test.php on line 5
Warning: simplexml_load_string(): ^ in /Applications/MAMP/htdocs/test.php on line 5
So hey! I know your pain!
Anyway, the quick solution I tried is to use trim on the $xml_file to get rid of extraneous white space at the beginning & end of the of the file like this:
$xml_file = file_get_contents('test.xml');
$xml = simplexml_load_string(trim($xml_file));
echo '<pre>';
print_r($xml);
echo '</pre>';
And all works great!
