我的 ERP 系统中有一个结构很差的 XML 源，并且标题到详细信息的父/子关系被颠倒了，因为在运行时，直到第一个详细记录被处理时才知道父（键）。这是由于旧的 DB2 大型机应用程序的接口的编写方式。不幸的是，我无权修改报告，也无权更改报告，所以我必须按原样处理源。

XML 输出如下所示：

<report>
    <detail>
        <header>
            <keyfield>1231</keyfield>
            <headerfield1>foo</headerfield>
            <headerfield2>bar</headerfield2>
        </header>
        <keymatch>1231</keymatch>
        <detailfield0>Line1</detailfield0>
        <detailfield1>this is bad structure</detailfield1>
        <detailfield2>and not my design</detailfield2>
    </detail>
    <detail>
        <keymatch>1231</keymatch>
        <detailfield0>Line2</detailfield0>
        <detailfield1>this is bad structure</detailfield1>
        <detailfield2>and not my design</detailfield2>
    </detail>
    <detail>
        <keymatch>1231</keymatch>
        <detailfield0>Line3</detailfield0>
        <detailfield1>this is bad structure</detailfield1>
        <detailfield2>and not my design</detailfield2>
    </detail>
    <detail>
        <keymatch>1231</keymatch>
        <detailfield0>Line4</detailfield0>
        <detailfield1>this is bad structure</detailfield1>
        <detailfield2>and not my design</detailfield2>
    </detail>
    <detail>
        <keymatch>1231</keymatch>
        <detailfield0>Line5</detailfield0>
        <detailfield1>this is bad structure</detailfield1>
        <detailfield2>and not my design</detailfield2>
    </detail>
    <detail>
        <header>
            <keyfield>1232</keyfield>
            <headerfield1>boo</headerfield>
            <headerfield2>far</headerfield2>
        </header>
        <keymatch>1232</keymatch>
        <detailfield0>Line1</detailfield0>
        <detailfield1>this is bad structure</detailfield1>
        <detailfield2>and not my design</detailfield2>
    </detail>
    <detail>
        <keymatch>1232</keymatch>
        <detailfield0>Line2</detailfield0>
        <detailfield1>this is bad structure</detailfield1>
        <detailfield2>and not my design</detailfield2>
    </detail>
    <detail>
        <keymatch>1232</keymatch>
        <detailfield0>Line3</detailfield0>
        <detailfield1>this is bad structure</detailfield1>
        <detailfield2>and not my design</detailfield2>
    </detail>
    <detail>
        <keymatch>1232</keymatch>
        <detailfield0>Line4</detailfield0>
        <detailfield1>this is bad structure</detailfield1>
        <detailfield2>and not my design</detailfield2>
    </detail>
    <detail>
        <keymatch>1232</keymatch>
        <detailfield0>Line5</detailfield0>
        <detailfield1>this is bad structure</detailfield1>
        <detailfield2>and not my design</detailfield2>
    </detail>
</report>

最终，我需要它采用类似于以下的格式：

<report>
    <header>
        <keyfield>1231</keyfield>
        <headerfield1>foo</headerfield>
        <headerfield2>bar</headerfield2>
            <detail>
                <keymatch>1231</keymatch>
                <detailfield0>Line1</detailfield0>
                <detailfield1>this is bad structure</detailfield1>
                <detailfield2>and not my design</detailfield2>
            </detail>
            <detail>
                <keymatch>1231</keymatch>
                <detailfield0>Line2</detailfield0>
                <detailfield1>this is bad structure</detailfield1>
                <detailfield2>and not my design</detailfield2>
            </detail>
            <detail>
                <keymatch>1231</keymatch>
                <detailfield0>Line3</detailfield0>
                <detailfield1>this is bad structure</detailfield1>
                <detailfield2>and not my design</detailfield2>
            </detail>
            <detail>
                <keymatch>1231</keymatch>
                <detailfield0>Line4</detailfield0>
                <detailfield1>this is bad structure</detailfield1>
                <detailfield2>and not my design</detailfield2>
            </detail>
            <detail>
                <keymatch>1231</keymatch>
                <detailfield0>Line5</detailfield0>
                <detailfield1>this is bad structure</detailfield1>
                <detailfield2>and not my design</detailfield2>
            </detail>
    </header>
    <header>
        <keyfield>1232</keyfield>
        <headerfield1>boo</headerfield>
        <headerfield2>far</headerfield2>
            <detail>
                <keymatch>1232</keymatch>
                <detailfield0>Line1</detailfield0>
                <detailfield1>this is bad structure</detailfield1>
                <detailfield2>and not my design</detailfield2>
            </detail>
            <detail>
                <keymatch>1232</keymatch>
                <detailfield0>Line2</detailfield0>
                <detailfield1>this is bad structure</detailfield1>
                <detailfield2>and not my design</detailfield2>
            </detail>
            <detail>
                <keymatch>1232</keymatch>
                <detailfield0>Line3</detailfield0>
                <detailfield1>this is bad structure</detailfield1>
                <detailfield2>and not my design</detailfield2>
            </detail>
            <detail>
                <keymatch>1232</keymatch>
                <detailfield0>Line4</detailfield0>
                <detailfield1>this is bad structure</detailfield1>
                <detailfield2>and not my design</detailfield2>
            </detail>
            <detail>

                <detailfield0>Line5</detailfield0>
                <detailfield1>this is bad structure</detailfield1>
                <detailfield2>and not my design</detailfield2>
            </detail>
    </header>
</report>

诚然，我对 XSLT 了解不多，但我学得很快，我发现这是我需要使用的工具。值得一提的是，这是 JD Edwards 9.1，我将使用 BI Publisher 通过 XSL 模板发送数据，以便进一步移交给 EDI 合作伙伴。

谢谢，

试试这种方式：

XSLT 2.0

<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>

<xsl:template match="/report">
    <xsl:copy>
        <xsl:for-each-group select="detail" group-starting-with="detail[header]">
            <header>
                <xsl:copy-of select="header/*"/>
                <xsl:apply-templates select="current-group()"/>
            </header>
        </xsl:for-each-group>
    </xsl:copy>
</xsl:template>

<xsl:template match="detail">
    <xsl:copy>
        <xsl:copy-of select="* except header"/>
    </xsl:copy>
</xsl:template>

</xsl:stylesheet>
