I have a SimpleXMLElement object that I got from parsing a response from oData. I'm looping through the children and it works well as long as it has children (the truth is I'm not even sure if they are its children or if its just a collection). This is how my code looks like:
$dataset = soapService->doSoapCall();
$array = $dataset->children()->children();
foreach($rawArray as $element)
{
$row['Something'] = (string)$element->Something;
$newArr[] = $row;
}
The problem is that this code throws an error of: PHP Node no longer exists SimpleXML. I've been trying to check for null or check the count of it but I keep getting the same error. When I look at it from the debugger in net beans it just says its type SimpleXMLElement but I doesn't have any other value or children. Please help.
Note: When I do print_r($array) i get this:
SimpleXMLElement Object ( )
When the object actually has data it returns this:
SimpleXMLElement Object ( [Table] => Array ( [0] => SimpleXMLElement Object ( [EventCode] => 10020 ) [1] => SimpleXMLElement Object ( [EventCode] => 10030 ) [2] => SimpleXMLElement Object ( [EventCode] => 10040 ) ) ) {"code":99200}

i wont to list a set of files in a directory and the files in its sub directory using a loop rather than the function
as im getting the information about the directory through an xml based webdav and php native functions are infertile so please understand the issue has not yet been lodged here
$urlloc is used to remove the same directory from being looped again
foreach ($xml as $key) {
if(empty($key->propstat->prop->resourcetype[0])){
echo $key->href."<br/>";//files are printed, for debugging perposes im printing it
}else{
$Nurlloc=$key->href;
if ($Nurlloc!=$urlloc){
echo "<b>".$Nurlloc."</b><br/>";//directorys printed in bold for debugging
$urlloc=$Nurlloc;
//gtndirdown()
above is the method im getting to know if its a directory or not
NOTE i want to be able to make this code loop through and get me all the files in the directory i will also post the array of files im getting

iv been stuck in this issue for 4 days and i have would like if some one could come up with a logic for this issue
maybe this is an idea that you can implement in your logic
// the name of directory
$dir='path_to_your_directory';
$files = array_slice(scandir($dir), 2);
print_r($files);

So I am doing the following call to get the array.
$new_str = htmlspecialchars_decode($str);
$new_str = str_replace('<?xml version="1.0" encoding="UTF-8"?>','',$new_str);
$xml = simplexml_load_string($new_str);
$dom = new SimpleXMLElement($new_str);
$xml_array = $dom->xpath("//*[name()='ReportSummary']");
echo "{$xml_array[0]['Score']}";
But I am unable to pull the object out of the Array. I am not sure if the array
is being correctly sent back to me due to the fact that if I don't decode the string I don't get a array back. The weird thing is that in the array I keep on seeing "SimpleXMLElement Object" and I am not sure if that is correct.
Any help will be appreciated.
As the dump output says, SimpleXML is a type of object, not a way of creating arrays.
These two lines are different ways of writing the same thing, you only need one of them; in either case you end up with a SimpleXMLElement object:
$xml = simplexml_load_string($new_str);
$xml = new SimpleXMLElement($new_str);
The outer array you are seeing is to hold the results of the XPath query, since they can come from anywhere in the XML tree. It is an array of SimpleXMLElement objects.
For how to access data using SimpleXML, see the basic usage page in the PHP manual.
In your case, Score is an element of the document, so needs to be accessed with the $node->property syntax.
Here's a tidied up version of your code:
$new_str = htmlspecialchars_decode($str);
// Are you sure the next line is necessary? That looks like a valid XML opening to me.
$new_str = str_replace('<?xml version="1.0" encoding="UTF-8"?>','',$new_str);
$xml = simplexml_load_string($new_str);
// I think this simpler XPath expression means the same as yours, but I might be wrong
$xpath_results = $xml->xpath('//ReportSummary');
// Beware that the XPath could return no matches, in which case the following
// would give an error. Best to check count($xpath_results) > 0 first.
echo $xpath_results[0]->Score;
To IMSoP: thanks for the help but I had to modify it a bit:
$dom = new SimpleXMLElement($new_str);
$xml_array = $dom->xpath("//*[name()='ReportSummary']");
echo $xml_array[0]->Score;
And from that I got the correct result, thanks a lot!
I would like to get methods from REST XML file via PHP.
I have local REST file, which is in this format:
SimpleXMLElement Object
(
[doc] => SimpleXMLElement Object
(
)
[resources] => SimpleXMLElement Object
(
[#attributes] => Array
(
[base] => https://**url**
)
[resource] => Array
(
[0] => SimpleXMLElement Object
(
[#attributes] => Array
(
[path] => xml/{accesskey}/project
)
[param] => SimpleXMLElement Object
(
[#attributes] => Array
(
[name] => accesskey
[style] => template
[type] => xs:string
)
)
[method] => SimpleXMLElement Object
(
[#attributes] => Array
(
[id] => getAllProjects
[name] => GET
)
[response] => SimpleXMLElement Object
(
[representation] => SimpleXMLElement Object
(
[#attributes] => Array
(
[mediaType] => application/xml; charset=utf-8
)
)
)
)
... and so on
I have the following code, but it returns just the first method name:
$file="application.wadl";
$xml = simplexml_load_file($file);
foreach($xml->resources[0]->resource->method->attributes() as $a => $b) {
echo $b,"\n";
}
I would like to extract all of them, not just the first one. How to do that?
Rather than looping over the attributes of one element, you need to loop over all the elements with the same name. Due to the magic of SimpleXML, this is as simple as this:
foreach($xml->resources->resource->method as $method) {
echo $method['id'],"\n";
}
When followed immediately by another operator, as with ->resources, SimpleXML assumes you just want the first element with that name. But if you loop over, it will give you each of them, as a SimpleXML object.
EDIT : It looks like the nesting of your XML means you need some form of recursion (you need to look at $xml->resources->resource->resource->resource->method etc).
Something like this perhaps (untested example)?
function get_methods($base_url, $node)
{
$all_methods = array();
// Child resources: build up the path, and recursively fetch all methods
foreach ( $node->resource as $child_resource )
{
$child_url = $base_url . '/' . (string)$child_resource['path'];
$all_methods = array_merge(
$all_methods,
get_methods($child_url, $child_resource)
);
}
// Methods in this resource: add to array directly
foreach ( $node->method as $method )
{
$method_url = $base_url . '/' .(string)$method['id'];
$all_methods[$method_url] = (string)$method['id'];
}
return $all_methods;
}
print_r( get_methods('/', $xml->resources) );
Incidentally, print_r won't always give you the best view of a SimpleXML object, because they are actually wrappers around non-PHP code. Try this simplexml_dump() function instead.
I am trying to iterate over set of nodes given by xpath and set certain attribute for each node. However it works only for nodes withou content or with empty (whitespace) content. I have tried 2 approaches but with the same result (maybe they are both the same on some deeper level, dunno). The commented line is the second approach.
$temp = simplexml_load_string (
'<toolbox>
<hammer/>
<screwdriver> </screwdriver>
<knife>
sharp
</knife>
</toolbox>' );
echo "vanilla toolbox: ";
print_r($temp);
$nodes = $temp->xpath('//*[not(#id)]');
foreach($nodes as $obj) {
$tempdom = dom_import_simplexml($obj);
$tempdom->setAttributeNode(new DOMAttr('id', 5));
//$obj->addAttribute('bagr', 5);
}
echo "processed toolbox: ";
print_r($temp);
This is output. Attribute id is missing in node knife.:
vanilla toolbox: SimpleXMLElement Object
(
[hammer] => SimpleXMLElement Object
(
)
[screwdriver] => SimpleXMLElement Object
(
[0] =>
)
[knife] =>
sharp
)
processed toolbox: SimpleXMLElement Object
(
[#attributes] => Array
(
[id] => 5
)
[hammer] => SimpleXMLElement Object
(
[#attributes] => Array
(
[id] => 5
)
)
[screwdriver] => SimpleXMLElement Object
(
[#attributes] => Array
(
[id] => 5
)
[0] =>
)
[knife] =>
sharp
I'm unable to reproduce what you describe, the changed XML is:
<?xml version="1.0"?>
<toolbox id="5">
<hammer id="5"/>
<screwdriver id="5"> </screwdriver>
<knife id="5">
sharp
</knife>
</toolbox>
Demo
It's exactly your code, maybe you're using a different LIBXML version? See the LIBXML_VERSION constant (codepad viper has 20626 (2.6.26)).
But probably it's just only the print_r output for a SimpleXMLElement object.
It does not output the attributes for the last element, even on a brand new object, but it's still possible to access the attribute. Demo.
You will see when you print_r($temp->knife['id']); that the attribute is set (as you can see in the earlier XML output).
When I print_r($var) I get the result below.
SimpleXMLElement Object
(
[SEND_FILE] => SimpleXMLElement Object
(
[FILEID] => 123
[GUID] => 456
[SUMMARY] => SimpleXMLElement Object
(
[NB_PAYMENTS] => 1
)
)
)
How can I get the value of the FILEID element in a variable? If I do
print $result->SEND_FILE->FILEID[0]
then I just get the number - what I want, no mention of a SimpleXML Object.
But if I put this variable in an array, as such
$res['file_id'] = $result->SEND_FILE->FILEID[0]
and then print_r($res) I get:
Array
(
[file_id] => SimpleXMLElement Object
(
[0] => 307466
)
)
How can I get it to remove the [0] / SimpleXMLElement Object?
This will look not too elegant, but try casting the result to integer (if the type is known):
$res['file_id'] = (int)$result->SEND_FILE->FILEID[0]
Why do you append the [0] at the end? You dont need that. You should simply do
print $result->SEND_FILE->FILEID;
And that should be enough.
