如何使用 PHP 脚本编辑 XML 文件格式 - How to edit XML file format using PHP script

我需要制作一个php脚本，将一个xml文件重新格式化为另一个xml文件

最好的

方法是什么？simpleXML似乎是解决方案，但我无法从每个标签中提取值并将其放入正确的格式文件中。

$xml = simplexml_load_file("file.xml");
//print_r($xml);
$array = json_decode(json_encode((array)$xml), TRUE);

例如。

原始 XML

有

几种可能的方法可以使用 xml。虽然您可以使用 DOM 和 SAX 方法，但转换 xml 的任务直接由 XSLT 技术解决。

编写 xsl-stylesheet 后，您可以使用 php 或独立的 xstl-处理器（如 SAXON）将其应用于原始 xml。

使用 XSLT 还可以从 IDE 支持中受益。像NetBeans，IntellijIDEA/PHPStorm这样的IDE提供了工具来舒适地编写和调试XSLT样式表。

考虑一下这个 XSLT，尽管它可能并不理想，因为我已经很久没有练习 XSLT 了：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" indent="yes" doctype-system="ADI.DTD"/>
    <xsl:template match="/">
        <xsl:element name="ADI">
            <xsl:apply-templates select="*"/>
        </xsl:element>
    </xsl:template>
    <xsl:template match="Metadata">
        <xsl:element name="Metadata">
            <xsl:apply-templates select="AMS"/>
            <xsl:for-each select="App_Data">
                <xsl:copy-of select="."/>
            </xsl:for-each>
        </xsl:element>
    </xsl:template>
    <xsl:template match="Asset">
        <xsl:element name="Asset">
            <xsl:apply-templates/>
        </xsl:element>
    </xsl:template>
    <xsl:template match="Content">
        <xsl:copy-of select="."/>
    </xsl:template>
    <xsl:template match="AMS">
        <xsl:element name="AMS">
            <xsl:apply-templates select="@*"/>
        </xsl:element>
    </xsl:template>

    <xsl:template match="@Provider">
        <xsl:attribute name="Provider">

        </xsl:attribute>
    </xsl:template>
    <xsl:template match="@Provider_ID">
        <xsl:attribute name="Provider_ID">
            <xsl:text>astral.com</xsl:text>
        </xsl:attribute>
    </xsl:template>
    <xsl:template
            match="@Product|@Asset_Name|@Version_Major|@Version_Minor|@Description|@Creation_Date|@Asset_ID|@Asset_Class">
        <xsl:copy-of select="."/>
    </xsl:template>
