在 XSL 中循环 XML 元素

发布于 2024-11-27 08:29:05 字数 1302 浏览 0 评论 0原文

我在这样的 XML 文件中

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

使用以下 XSL 代码来获取 FieldRef 值。

<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]* 循环来一一获取值，它不返回任何内容。我想通过循环将 FieldRef 值分配给 @Name 变量。

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>

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>

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.

这是显而易见的：

match="FieldRef[@Name='ViewFields/FieldRef[1]/@Name']"。没有 Name 属性将字符串 'ViewFields/FieldRef[1]/@Name' 作为字符串值。您很可能需要一个 XPath 表达式，而不是字符串。使用 match="FieldRef[@Name=ViewFields/FieldRef[1]/@Name]"
提供的 XML 文档中没有带有字符串值的 Name 属性“Completed” 或字符串值 “In Progress”。
此外，XML 文档中根本不存在任何 Status 属性。

您的问题没有正确回答所需的所有上下文，但您应该考虑将循环的构造简化为“for-each”。

给定 xml

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

和 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>

这可能更接近您想要的。

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.

given xml

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

with 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>

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