Question

我有以下XML：

<?xml version="1.0" encoding="UTF-8"?>
<ODM FileOID="some oid" Description="some desc" CreationDateTime="2010-10-06T22:35:00-06:00" FileType="Snapshot" >

            </FormDef>
            <ItemGroupDef OID="IG01" Name="Ungrouped" Repeating="No" SASDatasetName="UNGROUPE">
                <ItemRef ItemOID="I01" OrderNumber="1" Mandatory="Yes"/>
                <ItemRef ItemOID="I02" OrderNumber="2" Mandatory="Yes"/>
                <ItemRef ItemOID="I03" OrderNumber="3" Mandatory="Yes"/>
            </ItemGroupDef>
            <ItemGroupDef OID="IG02" Name="Reasons2" Repeating="Yes" SASDatasetName="REASONS2">
                <ItemRef ItemOID="I04" OrderNumber="1" Mandatory="No"/>
            </ItemGroupDef>
            <ItemGroupDef OID="IG03" Name="Ungrouped" Repeating="No" SASDatasetName="UNGRO002">
                <ItemRef ItemOID="I05" OrderNumber="1" Mandatory="Yes"/>
                <ItemRef ItemOID="I06" OrderNumber="2" Mandatory="Yes"/>
            </ItemGroupDef>
        </MetaDataVersion>
    </Study>
</ODM>

我想要做的是，对于“Name”属性等于“Ungrouped”的每个<ItemGroupDef>元素，将此属性值更改为“XXX-Ungrouped”，其中XXX是OID属性的值对于有{child} <FormDef>＆gt;的<ItemGroupRef元素ItemGroupOID属性等于ItemGroupDef元素的OID属性。所有其他属性和该元素的所有子元素都应保持不变。

例如，对于上面的<ItemGroupDef OID="IG01">，Name属性应该从“Ungrouped”更改为“F01-Ungrouped”，因为此OID IG01显示为<FormDef OID="F01">元素的子元素。保证任何ItemGroupDef OID值仅显示为一个<FormDef>元素的子项。

转换应该仅对<ItemGroupDef>元素起作用，并且Name属性值为“Ungrouped”。 Name属性不是“Ungrouped”的所有<ItemGroupDef>元素和XML文件中的所有其他元素都应保持不变。

此样式表：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:key name="kOIDbyItemGroup" match="FormDef/@OID" 
             use="../ItemGroupRef/@ItemGroupOID"/>
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="ItemGroupDef/@Name[.='Ungrouped']">
        <xsl:attribute name="Name">
            <xsl:value-of select="concat(key('kOIDbyItemGroup',../@OID),
                                         '-',.)"/>
        </xsl:attribute>
    </xsl:template>
</xsl:stylesheet>

输出：

来自评论：

一个问题：XSLT输出像这样的元素<FormRef FormOID="F01" Mandatory="Yes"></FormRef>当原始元素是<FormRef FormOID="F01" Mandatory="Yes"/>。都这些都是正确的XML标准，但有没有办法告诉XSLT 输出元素完全相同格式？

可能（用MSXSL，Altova，Saxon，Oracle，XQSharp测试）

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:key name="kOIDbyItemGroup" match="FormDef/@OID"
                 use="../ItemGroupRef/@ItemGroupOID"/>
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="*[not(node())]">
        <xsl:element name="{name()}">
            <xsl:apply-templates select="@*"/>
        </xsl:element>
    </xsl:template>
    <xsl:template match="ItemGroupDef/@Name[.='Ungrouped']">
        <xsl:attribute name="Name">
            <xsl:value-of select="concat(key('kOIDbyItemGroup',../@OID),
                                             '-',.)"/>
        </xsl:attribute>
    </xsl:template>
</xsl:stylesheet>

输出：
