我正在尝试在模板内创建一个循环。我找到了 2 种方法，但它们都不起作用：

方法一：

<xsl:template name="recurse_till_ten">
    <xsl:param name="num">1</xsl:param> <!-- param has initial value of
1 -->
    <xsl:if test="not($num = 10)">
        ...do something
        <xsl:call-template name="recurse_till_ten">
            <xsl:with-param name="num">
                <xsl:value-of select="$num + 1">
            </xsl:with-param>
        </xsl:call-template>
    </xsl:if>
</xsl:template>

方法二：

<xsl:variable name="count" select="'5'"/> 
<xsl:for-eachselect="(//*)[position()&lt;=$count]"> 
 <!-- Repeated content Here --> 
 <!-- use position() to get loop index --> 
 <xsl:value-of select="position()"/>.<br/> 
</xsl:for-each>

方法1给出了以下错误：

元素模板只允许作为样式表的子元素

方法 2 没有显示任何内容，因为我使用另一个 position() 来显示一些输出：

<td>
        <xsl:if test='buildid = /cdash/etests/etest/buildid'>
                            <xsl:variable name='index' 
                                          select='2*count(preceding-sibling::build[buildid = /cdash/etests/etest/buildid])+position()' />
                            <xsl:value-of select="/cdash/etests/etest[position()=$index]/value" />
        </xsl:if>
                        </td>

如何创建一个应该在两次之间调用代码的循环？

我不确定您在方法 2 过程中要做什么，所以我将专注于第一个。

您需要将代码更新为这样的内容

<xsl:template name="recurse_till_ten">
    <xsl:param name="num" />
    <xsl:if test="not($num = 10)">
        ...do something
        <xsl:call-template name="recurse_till_ten">
            <xsl:with-param name="num" select="$num + 1" />
        </xsl:call-template>
    </xsl:if>
</xsl:template>

我所做的唯一重要更改是没有在循环中设置变量。通过将其设置在循环中，您将始终设置num = 1为无限循环。

因此，您可以通过这样做在模板中的其他位置调用它。

<xsl:call-template name="recurse_till_ten">
    <xsl:with-param name="num" select="number('1')" />
</xsl:call-template>

这应该允许您循环直到变量达到 10。
