【问题描述】：

我有一个 xml 文件，我希望将其转换为 csv 文件。我的 xml 文件是具有产品编号和两种属性的产品列表

attrtype=ProductattributeTypeTechData
attrtype=ProductattributeTypeScopeSupply

我设法获得了所有TypeTechData 属性，因为它应该全部放在一个文件中，但我无法弄清楚如何执行TypeScopeSupply。这是 XML 文件

我真正想要的是将每个产品保存在一个由产品 ID 命名的单独 csv 中如果TypeScopeSupply 的数据中有任何值并且只有这些属性的标题为dictionaryentry，则仅存储TypeScopeSupply 的数据。因为有一些TypeScopeSupply 里面没有任何值或者说是空的。我不希望这些空属性被回显。

另外需要注意的是TypeScopeSupply 的值可能为COLL-PRAT-VALUE 或只是PRAT-VALUE。即使我知道如何做到这一点，我也会很感激。我特意在这里放了一个更大的 xml 文件来显示产品属性的多样性。不同的产品有不同类型的属性。

<?php
$productfile = "Internet.xml";

//Build Product List
if (!$xml = simplexml_load_file($productfile)) {
echo "Unable to load XML file";
} else {
echo "<span style='white-space: nowrap'>";
$products = $xml->xpath('//PRV');
//Table Header
foreach ($products as $product) {
foreach ($product->COLL as $COLL) {
    foreach ($COLL->PRAT as $PRAT){
        if($COLL['attrtype']=="ProductattributeTypeScopeSupply"){
        $headerarray[] =  $COLL['dictionary_entry'];
        }
    };
    };
foreach ($product->PRAT as $PRAT) {
    if($PRAT['attrtype']=="ProductattributeTypeScopeSupply"){
    $headerarray[] =  $PRAT['dictionary_entry'];
    }
};
};
echo "ID,";

$headerarray = array_values(array_unique($headerarray));
//Build Seperate header array for woocommerce display
$header = implode($headerarray,"|");
$header = str_replace(",","",$header);
$header = explode("|",$header);
echo implode(",",$header);
echo "<br>";

//Build Stats Array
foreach ($products as $product) {
    echo($product->PRODUCT_NUMBER);
    echo ",";
    foreach ($product->COLL as $COLL) {
        if($COLL['attrtype']=="ProductattributeTypeScopeSupply"){
        $name = $COLL['dictionary_entry'];
        $unit = "";
        unset($values);
        foreach ($COLL->PRAT as $PRAT){
            foreach ($PRAT->VALUE as $VALUE) {
                $values[] = (string)$VALUE . $VALUE['unit'];
                };
            };
        $statsarray[(string)$name] = implode(array_filter($values),"|");
        }
    };
    foreach ($product->PRAT as $PRAT) {
        if($PRAT['attrtype']=="ProductattributeTypeScopeSupply"){
        $name = $PRAT['dictionary_entry'];
        $unit = "";
        unset($values);
            foreach ($PRAT->VALUE as $VALUE) {
                $values[] = (string)$VALUE . $VALUE['unit'];
                };
        $statsarray[(string)$name] = implode(array_filter($values),"|");
        }
    };

    //Compare against headers
    $statsarray = str_replace(",",".",$statsarray);
    $spreadsheetarray = array_fill(0, count($headerarray),"");
    foreach ($statsarray as $description=>$value) {
        $spreadsheetarray[array_search($description,$headerarray)]=$value;
    };
    foreach ($spreadsheetarray as $description=> $value) {
        $spreadsheetarray[$description] = str_replace(',','.',$value);
        //add column for woocommerce display
        //$spreadsheetarray[$description] = ",".$value;
    };
    echo (implode($spreadsheetarray,","));
    echo "<BR>";
    unset($statsarray);
    unset($spreadsheetarray);
    };
echo "</span>";
//End XML if
};
?>

这就是我设法做到的......当我在浏览器中查看它时，它会输出单个 csv 以及空值。所有标题及其值（包括此处打印的空值）我不知道如何避免空值及其标题并将其放入产品特定的 csv 中。

【问题讨论】：

因为你还没有开始编码，你可以使用simplexml_load_file来解析你的XML，然后从构建数组开始，最后在fputcsv()上使用它。
它对我有用。谢谢

【解决方案1】：

我将代码更改为以下代码，它对我有用。

 foreach ($product->COLL as $COLL) {
    foreach ($COLL->PRAT as $PRAT){
        if($COLL['attrtype']=="ProductattributeTypeScopeSupply"){
        $headerarray[] =  $COLL['dictionary_entry'];
        }
    };
    };
    foreach ($product->PRAT as $PRAT) {
    if($PRAT['attrtype']=="ProductattributeTypeScopeSupply"){
    $headerarray[] =  $PRAT['dictionary_entry'];
    }
    };

    //echo "ID,";
    $headerarray = array_values(array_unique($headerarray));

    foreach ($product->COLL as $COLL) {
        if($COLL['attrtype']=="ProductattributeTypeScopeSupply"){
        $name = $COLL['dictionary_entry'];
        $unit = "";
        unset($values);
        foreach ($COLL->PRAT as $PRAT){
            foreach ($PRAT->VALUE as $VALUE) {
                    if(!empty($name)) {
                    $values[] = (string)$VALUE.$VALUE['unit'];
                    }
                };
            };
        $statsarray[(string)$name] = $name." ".implode(array_filter($values),"|");
        }
    };
    foreach ($product->PRAT as $PRAT) {
        if($PRAT['attrtype']=="ProductattributeTypeScopeSupply"){
        $name = $PRAT['dictionary_entry'];
        $unit = "";
        unset($values);
            foreach ($PRAT->VALUE as $VALUE) {
                    if(!empty($name)){
                    $values[] = $name." ". (string)$VALUE .$VALUE['unit'];
                    }
                };
        $statsarray[(string)$name] = implode(array_filter($values),"|");
        }
    };
    $statsarray = str_replace(",",".",$statsarray);

    foreach ($statsarray as $description=>$value) {
        $spreadsheetarray[array_search($description,$headerarray)]=$value;

    };
    foreach ($spreadsheetarray as $description=> $value) {
        $spreadsheetarray[$description] = str_replace(',','.',$value);

    };
