Question

我有以下XML：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE SHOP PUBLIC "XSLT-compat" "">
<SHOP>
  <SHOPITEM>

    <FRAMESIZE>16"</FRAMESIZE>

    <PRODUCT_VARIANT id="5">

      <PRODUCT>TERRA 3.0</PRODUCT>
      <COLOR>black / green</COLOR>
      <PRICE>399.99</PRICE>
    </PRODUCT_VARIANT>
  </SHOPITEM>
</SHOP>

这是我目前循环使用XML的PHP代码：

foreach($xml->SHOPITEM as $izdelki)
{   
$artikel = (array)$izdelki;

$izdelek = array();
echo $artikel['PRODUCT'] . '-' . $artikel['COLOR'] . '-' . $artikel['FRAMESIZE'] . '<br>';

    //get product_variant elements
    foreach($xml->SHOPITEM->PRODUCT_VARIANT as $p_variant)
        {
            $artikel2 = (array)$p_variant;
            echo $artikel2['PRODUCT'] . '-' . $artikel2['COLOR'] . '-' . $artikel2['FRAMESIZE'] . " main code: " . $artikel['CODE'] . '<br>';
        }

}

输出：

TARKA 3.0-black / blue-16"
TARKA 3.0-black / blue-18" main code: 032,74
TARKA 3.0-black / blue-20" main code: 032,74
TARKA 2.0-black / green-16"
TARKA 3.0-black / blue-18" main code: 032,77
TARKA 3.0-black / blue-20" main code: 032,77
TARKA 1.0-black / red-16"
TARKA 3.0-black / blue-18" main code: 032,80
TARKA 3.0-black / blue-20" main code: 032,80
TERRA 3.0-matte black / red-17"
TARKA 3.0-black / blue-18" main code: 032,83
TARKA 3.0-black / blue-20" main code: 032,83

问题：输出绝对错误，foreach功能不是从产品到产品。你能指点一下这段代码在哪里破碎吗？

Answer 1

看起来您的第二个循环不会停留在当前SHOPITEM内。换句话说

foreach($xml->SHOPITEM->PRODUCT_VARIANT as $p_variant)

应该是

foreach($izdelki->PRODUCT_VARIANT as $p_variant)

SimpleXML：foreach - 缺少一些元素
