xml – 如何在XSLT中使用fn：replace(string,pattern,replace)

如何使用

fn:replace(string,pattern,replace)

在XSLT中

它是否像< FN：替换(...)/> ??

该函数指定如下：

fn:replace($input,$pattern,$replacement,[$flags])

$input        xs:string?  the string to change
$pattern      xs:string   regular expression to match the areas to be replaced
$replacement  xs:string   the replacement string
$flags        xs:string   flags for multiline mode,case insensitivity,etc
return value  xs:string

请注意,$pattern是一个regular expression,替换字符串也有一些特殊的替换语法.

这里有些例子：

# simple replacement
replace('query','r','as')               queasy

# character class
replace('query','[ry]','l')             quell

# capturing group substitution
replace('abc123','([a-z])','$1x')       axbxcx123

# practical example
replace('2315551212',[phone]
    '(\d{3})(\d{3})(\d{4})','($1) $2-$3'
)
