遍历XSL中的XML元素 [英] Loop through XML elements in XSL

问题描述

我在这样的XML文件中

I have in XML file like this

<ViewFields> 
<FieldRef Name="Approval Status" /> 
<FieldRef Name="Requirement Status" /> 
<FieldRef Name="Development Status" /> 
<FieldRef Name="Testing Status" />
</ViewStatus>

我有以下XSL代码来获取FieldRef值.

I have the following XSL code to get FieldRef values.

<xsl:template name="FieldRef_body.Status" match="FieldRef[@Name='ViewFields/FieldRef[1]/@Name']" mode="body">
        <xsl:param name="thisNode" select="."/>
            <xsl:choose>
                <xsl:when test="$thisNode/@*[name()=current()/@Name] = 'Completed'">
                    <img src="/_layouts/images/IMNON.png" alt="Status: {$thisNode/@Status}"/>
                </xsl:when>
                <xsl:when test="$thisNode/@*[name()=current()/@Name] = 'In Progress'">
                    <img src="/_layouts/images/IMNIDLE.png" alt="Status: {$thisNode/@Status}"/>
                </xsl:when>
                <xsl:otherwise>
                    <img src="/_layouts/images/IMNBUSY.png" alt="Status: {$thisNode/@Status}"/>
                </xsl:otherwise>
            </xsl:choose>
    </xsl:template>

我试图通过FieldRef * [x] *进行遍历以逐个获取值，但没有返回任何内容.我想通过循环将FieldRef值分配给@Name变量.

I am trying to LOOP through FieldRef*[x]* to get the values one by one, it's not returning anything. I want to assign FieldRef values to @Name variable through loop.

推荐答案

您的问题并不具有正确回答所需的所有上下文，但是您应该考虑将构造简化为"for-each"以进行循环

Your question doesn't have all of the context needed to answer correctly, but you should consider simplifying your construct down to a "for-each" for your looping.

提供xml

<ViewFields> 
<FieldRef Name="Approval Status" />
<FieldRef Name="Requirement Status" /> 
<FieldRef Name="Development Status" /> 
<FieldRef Name="Testing Status" />
</ViewFields>

使用xsl

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template name="main" match="/">
    <xsl:for-each select="/ViewFields/FieldRef">
        <xsl:choose>
            <xsl:when test="@Name = 'Approval Status'">
                <ApprovalStatus/>
            </xsl:when>
            <xsl:when test="@Name = 'Requirement Status'">
                <RequirementStatus/>
            </xsl:when>
            <xsl:otherwise>
                <SomethingElse/>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:for-each>
</xsl:template>

这可能会更接近您想要的东西.

This might be a bit closer to what you were wanting.
