このXMLファイルからカテゴリをエコーアウトしたい

Question

私は苦労しているXMLファイルにいくつかの問題があります。

私がしますprint_rを行うと出力はこのようになります。

SimpleXMLElement Object () SimpleXMLElement Object () SimpleXMLElement Object ([CATEGORYNAME] => Array ([0] => Automatik-maskin [1] => Borrmaskin)) SimpleXMLElement Object () 

XML：

<CATALOG> 
<ENGINE> 
    <TITLE>Another product</TITLE>

} //End of IF-statement 

} // foreachのループ

の終わり

XMLコードでわかるように、カテゴリの私のフィールドはCATEGORYNAMEと呼ばれていますが、この配列の出力方法を知ることはできません。他のすべてのフィールドをエコーするのは簡単だったが、私はサブフィールドなどのカテゴリに入れたときにエラーが発生した...

私は...

Answer 1

を倍のforeachのカップルを試してみましたあなたは、内側のループを配置することができますあなたのXMLからすべてのカテゴリを取得するためのループ。

$xml = simplexml_load_string($xml); 
foreach ($xml as $i){ 
    if(count($i->CATEGORIES->CATEGORYNAME) > 0) 
     foreach ($i->CATEGORIES->CATEGORYNAME as $category_name) 
      var_dump((string) $category_name); 
} 

最初のforeachはコードから取得されます。

Answer 2

簡体字コードは、カテゴリ名を取得する：あなたのコードを表示するこの

$xml = '<?xml version="1.0" encoding="UTF-8"?><CATALOG> 
<ENGINE> 
    <TITLE>Another product</TITLE> 
    <ARTNR>75</ARTNR> 
    <TEXT>This is another awesome product</TEXT> 
    <CATEGORIES></CATEGORIES> 
</ENGINE> 
<ENGINE> 
    <TITLE>Borrmaskin</TITLE> 
    <ARTNR>3530</ARTNR> 
    <TEXT>This is awesome</TEXT> 

    <QTY>10</QTY> 
    <CATEGORIES> 
      <CATEGORYNAME>Automatik-maskin</CATEGORYNAME> 
      <CATEGORYNAME>Borrmaskin</CATEGORYNAME> 
    </CATEGORIES> 
    <PRICE>10.90</PRICE> 
</ENGINE></CATALOG>'; 



$xmlcont = new SimpleXMLElement($xml); 

foreach ($xmlcont as $value) { 
    $val = $value->CATEGORIES->CATEGORYNAME; 
    foreach ($val as $key) { 
     echo $key."<br/>"; 
    } 

} 

OUTPUT

AUTOMATIK-マスキン

Borrmaskin
