xslt中的運算?
?粗略看了下xslt，做了點筆記：
1.字符串函數：contain('Welcome','e')：字符串包含，包含：true，不包含：false
???????????????????? concat('Welcome ', Name, '!')：字符連接
???????????????????? substring-before(string, pattern)
???????????????????? substring-after(string, pattern)
???????????????????? tarts-with(string, pattern)
???????????????????? substring(string, i, len?)
???????????????????? string-length(string)
???????????????????? translate(string, from-pattern, to-pattern)
???????????????????? 大小寫轉換:translate(“Hello”, “ABCDEFGHIJKLMNOPQRSTUVWXYZ”,
??????????????????????????????????????????????????????????? “abcdefghijklmnopqrstuvwxyz”);
2.布爾運算：<???????? >???? =??? <=?????? >=?????? !=
???????? <??? >??? =?? <=??? >=??? !=
3.算術運算：+, -, *, div, mod
?? 算術函數：sum(node set)? this function sums up all the values in the set of nodes
????????????????? floor(number) returns the largest integer that is not greater than number
????????????????????????????????????? Example.? floor(2.5) returns 2
????????????????? ceiling(number) returns the smallest integer that is not less than number
????????????????????????????????????? Example.? Ceiling(2.5) returns 3
????????????????? round(number) returns the integer closest to number
????????????????????????????????????? Example. round(2.3) returns 2
