你们有什么想法吗，我已经了解了xslt，我试着补充如下：

这是我的xslt文件：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="CONTACT">
        <xsl:copy>
               <PDE-Identity>
               <xsl:value-of select="generate-id(.)"/> 
               </PDE-Identity>
              <xsl:copy-of select="FirstName|LastName|URL"/>
              <Facebook-ID><!-- To extract the ID value from URL/Email -->
            <xsl:choose>
                <xsl:when test="URL">
                    <xsl:value-of select="substring-after(URL,'?id=')"/>
                </xsl:when>
                <xsl:otherwise>
                   <!-- <xsl:value-of select="substring-before(EMail[1],'@')"/>-->
                </xsl:otherwise>
            </xsl:choose>
        </Facebook-ID>
            <EMAILS>
                <xsl:apply-templates select="EMail"/>
            </EMAILS>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="EMail">
        <EMail Type="<xsl:value-of select="substring-before(substring-after(.,'@'), '.')"/>" Value="<xsl:value-of select="."/>"/>
    </xsl:template>

</xsl:stylesheet>

它没有起作用。伙计们，请帮帮我。示例代码；谢谢大家。

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="CONTACT">
        <xsl:copy>
            <xsl:copy-of select="FirstName|LastName"/>
            <EMAILS>
                <xsl:apply-templates select="EMail"/>
            </EMAILS>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="EMail">
        <EMail>
            <type><xsl:value-of select="substring-before(
                    substring-after(.,'@'),
                    '.')"/>
            </type>
            <value><xsl:value-of select="."/></value>
        </EMail>
    </xsl:template>

</xsl:stylesheet>

根据您的输入，将生成：

<?xml version="1.0" encoding="utf-8"?>

   <CONTACT>
      <FirstName>AfgZohal</FirstName>
