Question amout mtownsend/request-xml (XML to array) plugin - php

Question

Have a question about mtownsend/request-xml (XML to array) plugin.
So, plugin makes XML file to array.
I use it in my Laravel projects and there is several reason, because I need exact it, but here is one problem.
Have two simple XML files
first file oneitem.xml with one item <flat> into <post>
<?xml version="1.0" encoding="UTF-8"?>
<data>
<post>
<flat>
<roms>4</roms>
<baths>2</baths>
</flat>
</post>
</data>
second file severalitems.xml one with several items <flat> into <post>:
<?xml version="1.0" encoding="UTF-8"?>
<data>
<post>
<flat>
<roms>4</roms>
<baths>2</baths>
</flat>
<flat>
<roms>5</roms>
<baths>1</baths>
</flat>
<flat>
<roms>7</roms>
<baths>3</baths>
</flat>
</post>
</data>
Then, I use a simple code to make an array from this files, and show the result array for each:
$xmlone = XmlToArray::convert(file_get_contents('public/xml/test/oneitem.xml'));
$oneflat = $xmlone['post'];
print_r($oneflat);
$xmlseveral = XmlToArray::convert(file_get_contents('public/xml/test/severalitems.xml'));
$severalflats = $xmlseveral['post'];
print_r($severalflats);
If we try to make an array from first file (with one flat), and find all we have in posts we have this result:
Array ( [flat] => Array ( [roms] => 4 [baths] => 2 ) )
If we do the same in second file (with several `flat), we have this result
Array ( [flat] => Array ( [0] => Array ( [roms] => 4 [baths] => 2 ) [1] => Array ( [roms] => 5 [baths] => 1 ) [2] => Array ( [roms] => 7 [baths] => 3 ) )
So, if we have several items, plugin adds a additional arrays with keys, [0], [1], [2]....
I need to do it the same, even there is just one item flat into posts. So the results have same formats.
I know, that it makes plugin. If plugin see, that there is just one flat in post, he makes result array simple.
The code of main file of plugin is here, but I cant understand, which lines do it...
Thanks for your help
public static function convert($xml, $outputRoot = false)
{
$array = self::xmlStringToArray($xml);
if (!$outputRoot && array_key_exists('#root', $array)) {
unset($array['#root']);
}
return $array;
}
protected static function xmlStringToArray($xmlstr)
{
$doc = new DOMDocument();
$doc->loadXML($xmlstr);
$root = $doc->documentElement;
$output = self::domNodeToArray($root);
$output['#root'] = $root->tagName;
return $output;
}
protected static function domNodeToArray($node)
{
$output = [];
switch ($node->nodeType) {
case XML_CDATA_SECTION_NODE:
case XML_TEXT_NODE:
$output = trim($node->textContent);
break;
case XML_ELEMENT_NODE:
for ($i = 0, $m = $node->childNodes->length; $i < $m; $i++) {
$child = $node->childNodes->item($i);
$v = self::domNodeToArray($child);
if (isset($child->tagName)) {
$t = $child->tagName;
if (!isset($output[$t])) {
$output[$t] = [];
}
$output[$t][] = $v;
} elseif ($v || $v === '0') {
$output = (string) $v;
}
}
if ($node->attributes->length && !is_array($output)) { // Has attributes but isn't an array
$output = ['#content' => $output]; // Change output into an array.
}
if (is_array($output)) {
if ($node->attributes->length) {
$a = [];
foreach ($node->attributes as $attrName => $attrNode) {
$a[$attrName] = (string) $attrNode->value;
}
$output['#attributes'] = $a;
}
foreach ($output as $t => $v) {
if (is_array($v) && count($v) == 1 && $t != '#attributes') {
$output[$t] = $v[0];
}
}
}
break;
}
return $output;
}
}

Answer 1

Looks like its not posstible. As I understood, standart PHP tools to XML to array convertation makes it so. The plugin based on them.
Anyway, I think there is a way to solve it throught changing source code of this plugin, but I soleved in my situation, by workung with results of XML to array convertation, and check if result array have one flat or several.
