XSLT - 将值连接到现有值

时间：2017-01-16 18:25:02

标签： xml xslt xpath

我有以下XML：

enter image description here

我希望 id 成为子名+子名2的串联。示例：对于第一个id，将是：ThinkVision，第二个：LenovoMind

这是通过xsl：for-each吗？

实现的

我尝试使用以下xslt：

         

<xsl:template match="node()|@*">
    <xsl:copy>
        <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
</xsl:template>


<xsl:template match="/records/record/customList/customBucket[fn:lower-case(customName)='id']/customValue/text()">
    <xsl:for-each select="/records/record/customList">
        <xsl:value-of select="concat(customBucket[fn:lower-case(customName)='subname']/customValue/text(),customBucket[fn:lower-case(customName)='subname2']/customValue/text())"/>
    </xsl:for-each>
</xsl:template>

但是我得到了每个记录的连接而不是当前的记录：

enter image description here

示例XML：<records> <record> <customList> <customBucket> <customName>id</customName> <customValue>default</customValue> </customBucket> <customBucket> <customName>subname</customName> <customValue>Think</customValue> </customBucket> <customBucket> <customName>subname2</customName> <customValue>Vision</customValue> </customBucket> </customList> </record> <record> <customList> <customBucket> <customName>id</customName> <customValue>default</customValue> </customBucket> <customBucket> <customName>subname</customName> <customValue>Lenovo</customValue> </customBucket> <customBucket> <customName>subname2</customName> <customValue>Mind</customValue> </customBucket> </customList> </record> <record> <customList> <customBucket> <customName>id</customName> <customValue>default</customValue> </customBucket> <customBucket> <customName>subname</customName> <customValue>Think</customValue> </customBucket> <customBucket> <customName>subname2</customName> <customValue>Vision</customValue> </customBucket> </customList> </record> <record> <customList> <customBucket> <customName>id</customName> <customValue>default</customValue> </customBucket> <customBucket> <customName>subname</customName> <customValue>Mapped</customValue> </customBucket> <customBucket> <customName>subname2</customName> <customValue>Safe</customValue> </customBucket> </customList> </record> <record> <customList> <customBucket> <customName>id</customName> <customValue>default</customValue> </customBucket> <customBucket> <customName>subname</customName> <customValue>Sony</customValue> </customBucket> <customBucket> <customName>subname2</customName> <customValue>DCO</customValue> </customBucket> </customList> </record> </records>

基本上没有覆盖'id'，这里的想法是创建一个名为'newid'的新节点，其逻辑与方案1相同：子名+子名2的连接。

我添加了以下代码，但它没有重命名id。

    <xsl:template match="/customBucket[fn:lower-case(customName)='clientportfolioid']/customName/text()">

当你这样做时：

customList

您从/根节点开始选择所有 <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/> <xsl:strip-space elements="*"/> <!-- identity transform --> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="customBucket[customName='id']/customValue"> <xsl:copy> <xsl:value-of select="../../customBucket[customName='subname']/customValue" /> <xsl:value-of select="../../customBucket[customName='subname2']/customValue" /> </xsl:copy> </xsl:template> </xsl:stylesheet> 元素。您当前的上下文在此处不起作用。

要获得您正在寻找的结果，请尝试以下方法：

<xsl:template match="customBucket[customName='id']">
    <xsl:copy-of select="."/>
    <customBucket>
        <customName>newid</customName>
        <customValue>
            <xsl:value-of select="../customBucket[customName='subname']/customValue" />
            <xsl:value-of select="../customBucket[customName='subname2']/customValue" />
        </customValue>
    </customBucket>
</xsl:template>

加了：

对于您添加的方案，请将第二个模板更改为：

<xsl:template match="customBucket[customName='id']">
    <xsl:copy>
        <customName>
            <xsl:value-of select="$normRenamedID" />
        </customName>
        <xsl:apply-templates select="customValue"/>
    </xsl:copy>
    <customBucket>
        <customName>newid</customName>
        <customValue>
            <xsl:value-of select="../customBucket[customName='subname']/customValue" />
            <xsl:value-of select="../customBucket[customName='subname2']/customValue" />
        </customValue>
    </customBucket>
</xsl:template>

已添加2：

对于其他方案，请将第二个模板更改为：

[(Libri,50.0),(Proxis,20.0),(Proxis,45.0),(Amazon,45.0)]
