php - Adding new node to an xml string

Question

$result = "<QRYRESULT>
           <ISSUCCESS>Y</ISSUCCESS>
           <TRN_REF>2498297295729857927</TRN_REF>
           <WARNING>IF ANY WARNING</WARNING>
           </QRYRESULT>";

this is an XML string I am using. now I have to add a new node to this string (not a file). That is after adding the new node the XML string will look like the following. I am getting this XML string from another system in a variable so modifying the string manually is not an option.

$result = "<QRYRESULT>
           <ISSUCCESS>Y</ISSUCCESS>
           <TOKEN>some token</TOKEN>
           <TRN_REF>2498297295729857927</TRN_REF>
           <WARNING>IF ANY WARNING</WARNING>
           </QRYRESULT>";

how can I do that ??

First convert it into an XML object then add a node to it. Search PHP SimpleXML on SO — Hanky Panky, Jun 10 '15 at 07:03

Use eg. simplexml

$xml = new SimpleXMLElement($yourstring);
$xml->addChild('node_name', 'node_value');
echo $xml->asXML();

A variant without using XML and consistency check:

$result=str_replace("</ISSUCCESS>","</ISSUCCESS><TOKEN>some token</TOKEN>",$result);

this is messy and wide open to errors, I'd suggest to use an XML parser – michi Jun 10 '15 at 07:28
It works in this context, fast, library-independent and not resource-intensive :) – umka Jun 10 '15 at 08:34
