regexp:match()

Syntax

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

Parameters

targetString

The string to perform regular expression matching upon.

regExpString

The JavaScript style regular expression to evaluate.

flagsString Optional

An optional string containing character flags.

The character flags are:

g

Global match. 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.

Return value

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.

For example:

<xsl:for-each select="regExp:match('https://big.rakal.top/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 = https://big.rakal.top/en/docs/Firefox_3_for_developers
Part 2 = https
Part 3 = big.rakal.top
Part 4 =
Part 5 = /en/docs/Firefox_3_for_developers
