regexp:match() performs regular expression matching on a string, returning the submatches found as a result.

语法

regexp:match(targetString,regExpString[[,flagsString]])

参数

targetString: The string to perform regular expression matching upon.
regExpString: The JavaScript style regular expression to evaluate.
flagsString: An optional string containing character flags.

The character flags are:

g: 全局匹配; The submatches from every match in the string are returned. If this flag isn't specified, only the submatches from the first match are returned.
i: Case insensitive match; If this flag is specified, the match is performed in a case insensitive fashion.

Returns

A node set of match elements, each of which has the string value equal to a portion of the first parameter string as captured by the regular expression. If the match isn't a global one, the first match element has the value of the portion of the string matched by the entire regular expression.

例如:

<xsl:for-each select="regExp:match('http://developer.mozilla.org/en/docs/Firefox_3_for_developers',
                                   '(\w+):\/\/([^/:]+)(:\d*)?([^# ]*)')">
   Part <xsl:value-of select="position()" /> = <xsl:value-of select="." />
</xsl:for-each>

This code generates the following output:

Part 1 = http://developer.mozilla.org/en/docs/Firefox_3_for_developers
Part 2 = http
Part 3 = developer.mozilla.org
Part 4 =
Part 5 = /en/docs/Firefox_3_for_developers
