Testing for a substring in a string with contains() function

The function contains() returns boolean value "true" if the string supplied as the second argument is a part of the string which is given as the first argument. If no match is found "false" is returned.

                        indent="yes"
                        omit-xml-declaration="yes"/>

            <xsl:template  match="/aaa">
                  <xxx>
                        <xsl:value-of  select="contains('abcdef','cde')"/>
                  </xxx>
                  <yyy>
                        <xsl:value-of  select="contains(.,'world')"/>
                  </yyy>
                  <zzz>
                        <xsl:value-of  select="contains(.,'World')"/>
                  </zzz>
            </xsl:template>

      </xsl:stylesheet>
XML

      <aaa>Hello, world!</aaa>
