在php中合并XML文件 [英] Combining XML files in php

问题描述

我正在获取外部xml文件(通过文件交换)，并且能够读取和存储在数据库中(php/mysql). xml文件使用不同的名称压缩，有时几个文件一起压缩在一个文件夹中

I am getting external xml files (through file exchange) and I am able to read and store in the database (php/mysql). The xml files come zipped under different names and sometimes several files come together zipped in a folder

当文件夹只有1个xml文件时，我能够使用

When the folder has only 1 xml file,I am able to successfully unzip and read the content using

 $path = '/xmlFile'; 
   //the xmlFile names are in this format : xmFile-00001235.xml, 
   //xmlFile-000012390.xml, etc.   only first portions are consistent

   foreach (glob($path.'/xmlFile-*.xml') as $filename) 

  {
  $xml=file_get_contents($filename);    

   }
   //store in database and unlink the xml file

这仅在文件夹具有一个xml文件的情况下有效，因为我在存储后取消链接该xml文件，它取消了所有文件的链接，但仅存储了一个文件.

This only works if the folder has one xml file, because I am un-linking the xml file after storage, it un-links all the files but only stores one

什么是最好的方法?我正在考虑检查文件夹中是否包含1个以上的xml并合并xml文件?也许一个示例解决方案确实会有所帮助，

What would be the best approach; I am thinking of checking if the folder has more than 1 xml and combine the xml files? maybe a sample solution will really help,

示例xml如下

xml1.xml

<sales>
    <row id="000001" saleid="267158" amountSold="2000"  />
    <row id="000001" saleid="267159" amountSold="80.000" />
 </sales>

xml2.xml

  <sales>
    <row id="000001" saleid="267160" amountSold="4000"  />
    <row id="000001" saleid="267161" amountSold="580" />
   </sales>

推荐答案

可以合并多个文件，例如...

Merging several files can be done something like...

function mergeFile ( DOMDocument $target, $fileName )    {
    $source = new DOMDocument();
    $source->load($fileName);

    foreach ( $source->getElementsByTagName("row") as $row )   {
        $import = $target->importNode($row, true);
        $target->documentElement->appendChild($import);
    }
}

$target = new DOMDocument();
$target->loadXML('<?xml version="1.0" encoding="utf-8"?><sales></sales>');
mergeFile($target, "NewFile.xml");
mergeFile($target, "NewFile1.xml");
mergeFile($target, "NewFile2.xml");

$target->save("out2.xml");

这使您可以继续将所有文件添加在一起，然后最后保存它们.

This allows you to keep on adding all of the files together and then saving them at the end.
