SimpleXML & PHP: Extract part of XML document & convert as Array?

This might help $obj = new SimpleXMLElement($xml); $rtn = array(); $cnt = 0; foreach($obj->xpath('///OSes/*/*') as $rec) { foreach ($rec as $rec_obj) { if (!isset($rtn$cnt)) { $rtn$cnt = array(); } foreach ($rec_obj as $name=>$val) { $rtn$cnt(string)$name = (string)$val; } ++$cnt; } }.

I never thought about this Xpath expression. Lovely! – Gaurish Aug 12 at 5:08.

Try this: // flatten: function arrayval1($any) { return array_values((array)$any); } function arrayval2($any) { return (array)$any; } // xml objects with xml objects: $oses = $xml->xpath('//OSes/*/*'); // an array of xml objects: $oses = array_map('arrayval1', $oses); // merge to a flat array: $oses = call_user_func_array('array_merge', $oses); // xml objects -> arrays $oses = array_map('arrayval2', $oses); print_r($oses); My result: Array ( 0 => Array ( id => centos5-32 name => CentOS 5 - 32 bit version => 5 architecture => 32 os => centos ) 1 => Array ( id => centos5-64 name => CentOS 5 - 64 bit version => 5 architecture => 64 os => centos ) 2 => Array ( id => centos6-32 name => CentOS 6 - 32 bit version => 6 architecture => 32 os => centos ) 3 => Array ( id => centos6-64 name => CentOS 6 - 64 bit version => 6 architecture => 64 os => centos ) 4 => Array ( id => ubuntu10-32 name => Ubuntu 10 - 32 bit version => 10 architecture => 32 os => ubuntu ) 5 => Array ( id => ubuntu10-64 name => Ubuntu 10 - 64 bit version => 10 architecture => 64 os => ubuntu ) ) If you're using PHP >= 5.3 (ofcourse you are, why whouldn't you) you can omit the nasty tmp function definitions and use cool anonymous functions for the mapping: // an array of xml objects: $oses = array_map(function($os) { return array_values((array)$os); }, $oses).

By modifying the xpath as others suggested as well, I came to this conclusion. It works with one helper function to re-format each xpath result node and uses array_reduce to iterate over the result. It then returns the converted result (Demo): $xml = new SimpleXMLElement($xmlstr); $elements = array_reduce( $xml->xpath('//OSes/*/*'), function($v, $w) { $w = array_values((array) $w); // convert result to array foreach($w as &$d) $d = (array) $d; // convert inner elements to array return array_merge($v, $w); // merge with existing }, array() // empty elements at start ); Output: Array ( 0 => Array ( id => centos5-32 name => CentOS 5 - 32 bit version => 5 architecture => 32 os => centos ) 1 => Array ( id => centos5-64 name => CentOS 5 - 64 bit version => 5 architecture => 64 os => centos ) 2 => Array ( id => centos6-32 name => CentOS 6 - 32 bit version => 6 architecture => 32 os => centos ) 3 => Array ( id => centos6-64 name => CentOS 6 - 64 bit version => 6 architecture => 64 os => centos ) 4 => Array ( id => ubuntu6-64 name => Ubuntu 10 - 32 bit version => 10 architecture => 32 os => ubuntu ) 5 => Array ( id => ubuntu6-64 name => Ubuntu 10 - 64 bit version => 10 architecture => 64 os => ubuntu ) ) I also opted for converting the original xpath result into an array of two levels, each time within the current level a key already exists, move the current entry to a new entry (Demo): try { $xml = new SimpleXMLElement($xmlstr); $elements = array(); $curr = NULL; foreach($xml->xpath('//id | //name | //version | //architecture | //os') as $record) { $key = $record->getName(); $value = (string) $record; if (!$curr || array_key_exists($key, $curr)) { unset($curr); $curr = array(); $elements = &$curr; } $curr$key = $value; } unset($curr); } catch(Exception $e) { echo $e->getMessage(); } Result is like this then: Array ( 0 => Array ( id => centos5-32 name => CentOS 5 - 32 bit version => 5 architecture => 32 os => centos ) 1 => Array ( id => centos5-64 name => CentOS 5 - 64 bit version => 5 architecture => 64 os => centos ) 2 => Array ( id => centos6-32 name => CentOS 6 - 32 bit version => 6 architecture => 32 os => centos ) 3 => Array ( id => centos6-64 name => CentOS 6 - 64 bit version => 6 architecture => 64 os => centos ) 4 => Array ( id => ubuntu6-64 name => Ubuntu 10 - 32 bit version => 10 architecture => 32 os => ubuntu ) 5 => Array ( id => ubuntu6-64 name => Ubuntu 10 - 64 bit version => 10 architecture => 64 os => ubuntu ) ).

Thanks for your help. Based on your solution, I adapted mine. Thanks again :) – Gaurish Aug 12 at 5:06.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
