php - Adding Nodes to Existing XML -

the problem having root xml being produced every time writes xml. main issue setting child , defining root. of Łza understand root xml node ignored. setup , create child , add content, , example of correct format is.

$xml = simplexml_load_file('filename.xml');  // load xml file need add if statment create if not exist  $result = $xml->addchild('result'); // ignore root node , add child results  $result->addchild('time', gmdate('d-m-y -h:i:s')); // rest of below adds child result , outputs results $result->addchild('channel', $site); $result->addchild('type', '**'); $result->addchild('process', $status); $result->addchild('sku', $code->sku); $result->addchild('item', $item); $result->addchild('status', '$feedback'); $result->addchild('errorid', '$error'); $result->addchild('message', '$message');  $xml->asxml('filename.xml');  //write file  // of above code using variables part of script 

the output be

<root>     <result>         <time>fri-may-2013 -09:15:22</time>         <channel>20</channel>         <type>**</type>         <process>update</process>         <sku>98746524765</sku>         <item/>         <status>problem</status>         <errorid>999-error</errorid>         <message>unknown file format support</message>     </result>     <result>         <time>fri-may-2013 -09:15:22</time>         <channel>20</channel>         <type>**</type>         <process>update</process>         <sku>5412254785</sku>         <item/>         <status>problem</status>         <errorid>123-error</errorid>         <message>invalid item</message>     </result> </root> 

thanks

try use simplexmlelement library instead hardcoded xml creation. maybe more complicate use @ begining, more safe (i mean avoid possible errors in xml structure when hardcode xml) , easy use when start use it. , easy add/remove nodes, childnodes.

this example code:

$xml = new simplexmlelement('<xml/>');  $data = $xml->addchild('data'); $result = $data->addchild('result'); $result->addchild('time', gmdate('d-m-y -h:i:s')); $result->addchild('channel', $siteid);  // ... , same way create xml nodes. // if want add next <result> node witch elements repeat code, (or put in loop if want more <result> elements): $result = $data->addchild('result'); $result->addchild('time', gmdate('d-m-y -h:i:s')); $result->addchild('channel', $siteid);  // , after create nodes save file: $xml->asxml('dherror.xml');  

above code create xml:

 <xml>   <data>    <result>      <time>fri-may-2013 -12:14:39</time>       <channel>data</channel>     </result>    <result>      <time>fri-may-2013 -12:14:39</time>       <channel>data</channel>     </result>   </data>  </xml> 

thats it. if need load , process xml easy:

to load file use:

$xml2 = simplexml_load_file('dherror.xml');  // add new node <result>: $resultnext = $xml2->data->addchild('result'); $resultnext->addchild('time', gmdate('d-m-y -h:i:s')); $resultnext->addchild('channel', $siteid);  //and save file $xml2->asxml('dherror.xml'); 

this create xml:

<?xml version="1.0" ?>   <xml>   <data>    <result>      <time>fri-may-2013 -12:27:24</time>       <channel>data</channel>     </result>    <result>      <time>fri-may-2013 -12:27:24</time>       <channel>data</channel>    </result>   <result>     <time>fri-may-2013 -12:27:24</time>      <channel>data</channel>    </result>  </data> </xml>
