使用XSL代码修改XML现有标签并新增标签的实现需求

Got it, let's work through this XML transformation request. The goal is to update the <1> element's content and add a new <5> element with two children, while keeping all other existing XML structure intact. Here's a clean XSLT solution that achieves exactly that:

XSLT Code #

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <!-- Identity template: copies all existing nodes (elements, attributes, text) as-is -->
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

    <!-- Override template to update <1> element's content -->
    <xsl:template match="1">
        <1>kkkkkkkk</1>
    </xsl:template>

    <!-- Override template to add new <5> element inside <EEE> -->
    <xsl:template match="EEE">
        <xsl:copy>
            <!-- Copy all existing children of <EEE> first -->
            <xsl:apply-templates select="@*|node()"/>
            <!-- Add the new <5> element with two child tags -->
            <5>
                <5a>new-child-content-1</5a>
                <5b>new-child-content-2</5b>
            </5>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

How It Works #

• Identity Template: This is the foundation of most XSLT transformations—it copies every node (elements, attributes, text nodes) from the input XML to the output, so we don't have to redefine rules for all the unchanged parts (like <AAA>, <BBB>, <CCC>, <DDD>, <2>, <3>, <4>).
• <1> Element Override: The template matching <1> replaces its original content with kkkkkkkk while keeping the element itself.
• <EEE> Element Override: We first copy all existing children of <EEE> (the updated <1>, plus <2>, <3>, <4>), then append the new <5> element with your specified child tags. You can adjust the names and content of the <5> child elements (<5a>, <5b>) to match your exact needs.

Sample Input & Output #

Input XML #

<AAA>
    <BBB>
        <CCC>
            <DDD>
                <EEE>
                    <1>abc</1>
                    <2>abc</2>
                    <3>abc</3>
                    <4>abc</4>
                </EEE>
            </DDD>
        </CCC>
    </BBB>
</AAA>

Output XML #

<AAA>
    <BBB>
        <CCC>
            <DDD>
                <EEE>
                    <1>kkkkkkkk</1>
                    <2>abc</2>
                    <3>abc</3>
                    <4>abc</4>
                    <5>
                        <5a>new-child-content-1</5a>
                        <5b>new-child-content-2</5b>
                    </5>
                </EEE>
            </DDD>
        </CCC>
    </BBB>
</AAA>
