Question

我有以下xml：

<?xml version="1.0"?>

          <node title="030. Travel Rewards" id="tcm:233-38884-4" url="/Skywards/travel_rewards/travel_rewards.aspx" indexpage="tcm:233-194320-64" compTitle="Travel Rewards" Group="yes"/>
          <node title="040. Journey Management Tools" id="tcm:233-38885-4" url="/Skywards/journey_management_tools/journey_management.aspx" indexpage="tcm:233-194322-64" compTitle="Journey Management "/>

        </node>
    </node>
    <node title="footer">
        <node title="F010. 000. Sitemap" id="tcm:233-192374-64" url="/sitetools/sitemap.aspx" accessKey="4" compTitle="Sitemap"/>
        <node title="F060. Accessibility" id="tcm:233-192369-64" url="/sitetools/accessibility.aspx" compTitle="Accessibility Statement"/>

    </node>
</navigation>

现在我想编写一个XSLT，它将检查Group =“Yes”并将呈现以下输出的XML：

<?xml version="1.0"?>
<navigation path="/english">

        <node title="040.

          <node title="040. Journey Management Tools" id="tcm:233-38885-4" url="/Skywards/journey_management_tools/journey_management.aspx" indexpage="tcm:233-194322-64" compTitle="Journey Management "/>
          <node title="050. Personal Travel Coordinator" id="tcm:233-38886-4" url="/Skywards/personal_travel_coordinator/personal_travel_coordinator.aspx" indexpage="tcm:233-194324-64" compTitle="Personal Travel Coordinator"/>

                <node title="030. Travel Rewards" id="tcm:233-38884-4" url="/Skywards/travel_rewards/travel_rewards.aspx" indexpage="tcm:233-194320-64" compTitle="Travel Rewards" Group="yes"/>            
                <node title="060. Skysurfers" id="tcm:233-38887-4" url="/Skywards/skysurfers/skysurfers.aspx" indexpage="tcm:233-194326-64" compTitle="Skysurfers" Group="yes"/>
            </node>
        </node> 
    </node>     
</navigation>

在上面输出的xml中，您可以看到添加了标题组的额外节点以及 Group =“yes”的子节点从顶部删除并在下面添加。< / p>

请建议!!

我将尝试使用以下解决方案进行上述问题：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">
    <xsl:strip-space elements="*"/>
    <xsl:output indent="yes"/>
    <xsl:template match="*">
        <xsl:copy>
            <xsl:copy-of select="@*"/>
            <xsl:apply-templates select="node()"/>
            <xsl:if test="self::navigation">
                <node title="Group">
                    <node>
                        <xsl:apply-templates select="node()" mode="group"></xsl:apply-templates>
                    </node>
                </node>
            </xsl:if>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="node" mode="group">
        <xsl:choose>
            <xsl:when test="@Group = 'yes'">
                <xsl:copy>
                    <xsl:copy-of select="@*"/>
                    <xsl:apply-templates select="node()" mode="group"/>
                </xsl:copy>            
            </xsl:when>
            <xsl:otherwise>
                <xsl:apply-templates select="node()" mode="group"/>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>
    <xsl:template match="*" mode="group"/>
</xsl:stylesheet>

XSLT 2.0解决方案。我不确定我是否完全理解了确切的目标，因此它适用于这个具体案例，但如果我误解了一些要求，则可能需要进行调整：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
    <xsl:output indent="yes"></xsl:output>
    <xsl:template match="/">
        <xsl:apply-templates></xsl:apply-templates>
    </xsl:template>
    <xsl:template match="*|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="node[@Group='yes' and not(exists(node()))]"/>
    <xsl:template match="node[@Group='yes' and exists(node())]">
        <xsl:copy>
            <xsl:apply-templates select="@*"/>
            <xsl:copy-of select="node[not(@Group='yes')]"/>
        </xsl:copy>        
    </xsl:template>
    <xsl:template match="node[@Group='yes' and exists(node())]" mode="groupOnly">
        <xsl:copy>
            <xsl:apply-templates select="@*[not(name()='Group')]"/>
            <xsl:copy-of select="node[@Group='yes']"/>
        </xsl:copy>        
    </xsl:template>
    <xsl:template match="navigation">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
            <node title="Group">
                <node>
                    <xsl:apply-templates select="//node[@Group='yes' and exists(node())]" mode="groupOnly"/>                                    
                </node>
            </node>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

我们的想法是逐个整个树，这是match="*|@*"模板的业务，然后为每个需要它的元素提供特定的模板。

然后我针对不同的情况使用不同的模式：预先存在的节点中的节点副本的默认模式。我在新节点元素中复制的节点的groupOnly模式。

如何使用xslt在现有xml中附加新节点
