如何从PHP中的XML解析变量

Question

Suppose I get XML content from a URL in a PHP variable (eg $new ).

Below is an example of this XML content:

<getResult>
[{"abc": "123","xyz":"234","mno":"we4r5t"}]
</getResult>

When I do the parsing of XML content in php like:-

$xmlObj = simplexml_load_string($new);
error_log($xmlObj->getResult);

I get [{"abc": "123","xyz":"234","mno":"we4r5t"}]

But I want to retrieve the inner content from the tag, eg retrieve the value of only abc OR xyz OR mno .

How can do that?

Answer 1

[{"abc": "123","xyz":"234","mno":"we4r5t"}]

That's not an XML-String it's a JSON object. You should parse it with json_decode ! http://php.net/manual/de/function.json-decode.php

Answer 2

Your XML markup contains JSON-formatted data.

You need to perform JSON parsing on this string to extract the desired values, using json_decode for instance:

$json = json_decode($xmlObj);
$abc = $json[0]["abc"];

Answer 3

$xmlObj = simplexml_load_string($new);
$json = json_decode($xmlObj->getResult);
error_log($json[0]['abc']); // 123

I've used $xmlObj->getResult like in your answer and I assume you didn't post code with error.
