Question

我有一个xml文件，我希望将其转换为csv文件。我的xml文件是包含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，因为它应该在一个文件中一起存在，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以产品ID命名的单独csv中如果TypeScopeSupply中有任何值，并且只有dictionaryentry的标题仅用于那些属性，则仅存储TypeScopeSupply的数据。因为有些TypeScopeSupply没有任何值，或者说是空的。我不希望这些空属性得到回应。

需要注意的其他事项是COLL-PRAT-VALUE的值可能为PRAT-VALUE或<?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 }; ?>。即使我知道如何做到这一点，我将不胜感激。我故意在这里放一个更大的xml文件，以显示产品属性的多样性。不同的产品具有不同类型的属性。

这就是我设法做的事情。当我在浏览器中查看时，它会输出一个带有空值的csv。所有标题及其值（包括空值在此处打印）我不知道如何避免空值及其标题并将其放在特定于产品的csv中。

我将代码更改为以下内容，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);

    };

使用php从xml创建一个csv
