如何使用 PHP 解压缩 xml 文件

Question

我的 PHP 系统上有一个压缩的 XML 文件。

如何解压缩以将其加载到 XMLDOM？

我每个 zip 存档只有一个 XML 文件。

提前致谢。

Answer 1

您可以使用 php 类 ZipArchive and DOMDocument 即：

<?php
//set the correct xml headers to output to browser
header("Content-type: text/xml");
$zipFile = "file.zip";
$zip = new ZipArchive;
if ($zip->open($zipFile))
{
    //get the xml filename inside the zip
    $xmlFile =  $zip->getNameIndex(0); //you only  have 1 xml file iside of the zip
    $zip->close();
    //read the xml file inside the zip without extracting it to disk (memory)
    $xml = file_get_contents("zip://$zipFile#$xmlFile");
    //create a new document
    $dom = new DOMDocument('1.0', "UTF-8");
    //load teh xml file
    $dom->loadXML($xml);
    //Here you can  manipulate the XML dom , add, remove nodes, etc.
    //save and echo the XML
    echo $dom->saveXML();
} else {
    echo 'zip open failed failed';
}

备注：

How do I ask a good question?
我用 this xml file 测试了代码，它按预期工作。
