一起<；说明>；元素if<；特征类型>；元素在XML PHP解析中是相同的

xml.php

需要这样的输出吗

      SimpleXMLElement Object
    (
        [feature_type] => Copier Features
        [description] => Copier description1
                         Copier description2  
    )
    SimpleXMLElement Object
    (
        [feature_type] => Facsimile Features
        [description] => Facsimile description1
                         Facsimile description2
    )

这样做：

$xml = simplexml_load_string($xmlstr,'SimpleXMLElement', LIBXML_NOCDATA);

$x = count($xml->product_features->feature_item)-1;
$ft = ''; $d = '';

for ($x ; $x >= 0 ; $x--) {

    if ($ft == (string)$xml->product_features->feature_item[$x]->feature_type) {

        $xml->product_features->feature_item[$x]->description = $xml->product_features->feature_item[$x]->description . " $d";

    } else {

        $ft = (string)$xml->product_features->feature_item[$x]->feature_type;
        $d = (string)$xml->product_features->feature_item[$x]->description;
        unset($xml->product_features->feature_item[$x]);
    }   
}

echo "<pre>";
var_dump($xml);
echo "</pre>";

$xml=simplexml\u load\u字符串（$xmlstr，'simplexmlement'，LIBXML\u NOCDATA）；
$x=计数（$xml->product\u features->feature\u item）-1；
$ft=''$d=''；
对于（$x；$x>=0；$x--）{
如果（$ft==（字符串）$xml->product\u features->feature\u item[$x]->feature\u type）{
$xml->product\u features->feature\u item[$x]->description=$xml->product\u features->feature\u item[$x]->description.“$d”；
}否则{
$ft=（字符串）$xml->product\u features->feature\u item[$x]->feature\u type；
$d=（字符串）$xml->product\u features->feature\u item[$x]->description；
取消设置（$xml->product\u features->feature\u item[$x]）；
}   
}
回声“；
    $xml = simplexml_load_file('xml.php','SimpleXMLElement', LIBXML_NOCDATA); 
    foreach($xml as $rows)
    {    
        foreach($rows as $row){ 
                       echo "<pre>";
                      print_r($row);
                       echo "</pre>";
        }
    }

var_dump（$xml）；
回声“；
    $xml = simplexml_load_file('xml.php','SimpleXMLElement', LIBXML_NOCDATA); 
    foreach($xml as $rows)
    {    
        foreach($rows as $row){ 
                       echo "<pre>";
                      print_r($row);
                       echo "</pre>";
        }
    }

在描述之间添加空格。
见现场演示：

$xml = simplexml_load_string($xmlstr,'SimpleXMLElement', LIBXML_NOCDATA);

$x = count($xml->product_features->feature_item)-1;
$ft = ''; $d = '';

for ($x ; $x >= 0 ; $x--) {

    if ($ft == (string)$xml->product_features->feature_item[$x]->feature_type) {

        $xml->product_features->feature_item[$x]->description = $xml->product_features->feature_item[$x]->description . " $d";

    } else {

        $ft = (string)$xml->product_features->feature_item[$x]->feature_type;
        $d = (string)$xml->product_features->feature_item[$x]->description;
        unset($xml->product_features->feature_item[$x]);
    }   
}

echo "<pre>";
var_dump($xml);
echo "</pre>";
