我需要创建一个php脚本，将一个xml文件重新格式化为另一个xml文件
最好的办法是什么？ simpleXML似乎是解决方案，但我无法从每个标记中提取值并将其放入正确的格式化文件中。
$xml = simplexml_load_file("file.xml");
//print_r($xml);
$array = json_decode(json_encode((array)$xml), TRUE);
例如
原始xml
<?xml version="1.0" encoding="ISO-8859-1"?>

答案 0 :(得分：1)
有几种方法可以使用xml。虽然您可以使用DOM和SAX方法，但XSLT technology直接解决了转换xml的任务。
撰写xsl-stylesheet后，您可以将其应用于原始xml with php或使用独立的xstl处理器（如SAXON）。
使用XSLT也可以从IDE支持中受益。像NetBeans，IntellijIDEA / PHPStorm这样的IDE可以使用工具来轻松地编写和调试XSLT样式表。
考虑一下这个XSLT，虽然它可能并不理想，因为我已经很长时间没有实践过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:text>FAMILY</xsl:text>
</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>
</xsl:stylesheet>
