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：
原文链接：https://www.f2er.com/xml/292479.htmlfn: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',(231) 555-1212
'(\d{3})(\d{3})(\d{4})','($1) $2-$3'
)
