xml - XPath contains() 条件含义？

Question

我试图解释以下条件的含义:

<xsl:when test="contains($name,'|') or contains($name,'%7c') or contains($name,'%7C')"> 

以上是否检查变量 name有 |在其中 OR 有 7 个小写字符或 7 个大写字符？

Answer 1

不，它检查是否 $name包含任何指定的文字子字符串:|或 %7c或 %7C .

见 XML XPath Language (XPath), Version 1.0, W3C Recommendation :

Function: boolean contains(string, string)

The contains function returns true if the first argument string contains the second argument string, and otherwise returns false.
