Question

我想将XML元素的值与字符串进行比较，并根据结果分配变量。但是这不起作用所以我把if语句设为1 = 1或另一次尝试是1 ='1'，但是仍未分配变量，我假设if语句没有触发。代码如下：

    <?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:param name="id"/>
    <xsl:template match="/">    
        <xsl:if test="mainData/info/country[@name=$id]">
        <xsl:for-each select="mainData/info/country[@name=$id]">
        <xsl:if test="1 = 1"><!--should always fire-->
            <xsl:variable name="color" select='"red"'/>
        </xsl:if>
        <div class="modal-content">
            <div class="row" id="top-content">
            <div class="col 6 top-modal">
            <div class="card card-modal">
                <div class="card-image">
                    <img alt="Country Flag"><xsl:attribute name="src"><xsl:value-of select="flag" /></xsl:attribute></img>
                </div>
                <div class="card-content">
                    <span class="card-title"><xsl:value-of select="@name"/></span>
                </div>
            </div>
            </div>
            <div class="col 6 top-modal">
            <div class="card card-modal">
                <div class="card-panel blue accent-3 modal-card-info">
                    <span class="white-text">

            <h6>Golds: <xsl:value-of select="medals/gold"/></h6>
            <h6>Silvers: <xsl:value-of select="medals/silver"/></h6>
            <h6>Bronze: <xsl:value-of select="medals/bronze"/></h6>
            <h6>Bronze: <xsl:value-of select="$color"/></h6><!-- check the var-->
                    </span>
                </div>
            </div>
            </div>
            </div>

        </xsl:if>

Answer 1

xsl:if正在解雇。您的问题是变量的范围。

<xsl:if test="1 = 1"><!--should always fire-->
    <xsl:variable name="color" select='"red"'/>
</xsl:if>

color变量的范围仅限于xsl:if的主体，而不是其他任何地方，因此您无法在其他地方使用它。

解决方案是将其更改为此，并将条件放在变量声明

中

<xsl:variable name="color">
    <xsl:if test="1 = 1">
        <xsl:text>red</xsl:text>
    </xsl:if>
</xsl:variable>

如果您有多种颜色选择，可以将其替换为xsl:choose。
