How-to break a for-each loop in XSLT?

推荐答案

XSLT 是以非常实用的风格编写的，在这种风格中没有与 break 语句等效的语句.你可以做的是这样的:

XSLT is written in a very functional style, and in this style there is no equivalent of a break statement. What you can do is something like this:

<xsl:for-each select="...nodes...">
    <xsl:if test="...some condition...">
        ...body of loop...
    </xsl:if>
</xsl:for-each>

这样 for-each 仍然会遍历所有节点，但循环体只有在条件为真时才会执行.

That way the for-each will still iterate through all the nodes, but the body of the loop will only be executed if the condition is true.
