我正在尝试在模板中创建一个循环。我找到了两种方法，但都不起作用:

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？

最佳答案

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。

您将希望将代码更新为这样的

<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。通过在循环中设置它，你总是在设置 num = 1这将导致无限循环。

因此，您可以通过执行此操作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。
