xslt - xsl :choose check all xsl:when conditions

Question

有什么办法不离开<choose>后第一 <when>匹配但继续检查其他条件？

Answer 1

我相信这是一个不。正如规范所说:

The content of the first, and only the first, xsl:when element whose test is true is instantiated. If no xsl:when is true, the content of the xsl:otherwise element is instantiated. If no xsl:when element is true, and no xsl:otherwise element is present, nothing is created.

你不能让它落入其他类似的情况。只需将其转换为一组 <xsl:if>如果您需要跌倒，请互相关注

更新 .这是 O'Reilly 的 XSLT 书籍 ( http://docstore.mik.ua/orelly/xml/xslt/ch04_02.htm ) 中的引述:

The C, C++, and Java switch statement is roughly equivalent to the element. The one exception is that procedural languages tend to use fallthrough processing. In other words, if a branch of the switch statement evaluates to true, the runtime executes everything until it encounters a break statement, even if some of that code is part of other branches. The element doesn't work that way. If a given evaluates to true, only the statements inside that are evaluated
