Question

我的ERP系统中存在结构非常差的XML源，并且Header to Detail的父/子关系被颠倒了，因为在运行时，直到第一个详细记录是父，才知道父（key）处理。这是由于编写旧DB2大型机应用程序的接口的方式。不幸的是，我无权修改报告，也没有任何动摇来改变报告，所以我必须按原样处理来源。

以下是XML输出的内容：

<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>

            </detail>
            <detail>

            </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>

    </header>

不可否认，我对XSLT了解不多，但我是一个快速学习，我发现这是我需要使用的工具。对于它的价值，这是JD Edwards 9.1，我将使用BI Publisher通过XSL模板发送数据，以便进一步切换到EDI合作伙伴。

谢谢，

以这种方式尝试：

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>
