string length

基本解釋

string-length("Brett") obviously returns 5, and normalize-space(" Brett McLaughlin ") returns "Brett McLaughlin".
string-length("Brett") 顯然返回 5，normalize-space(" Brett McLaughlin ") 則返回 "Brett McLaughlin"。
One improvement might be to generate a blind table for short paragraphs only (you can evaluate the length of a paragraph with the string-length() function).
改進方法之一可能是只對短的段生成隱形表（可以用 string-length() 函數(shù)計算段的長度）。
Rules for unnamed nodes are allowed but not often used (for example, *[string-length(.) > 10], which matches any element with more than 10 characters of text content).
允許使用未命名節(jié)點的規(guī)則，但這些規(guī)則并不常用（例如， *[string-length(.) > 10] ，它匹配任何文本內容多于 10 個字符的元素）。

- And because I'm writing out a string that's the same length -- -- my strings aren't getting shorter -- it's creating this illusion of some animation.
因為我寫了一個長度相同的字符串-,我的字符串不會變的更短-,它生成一個動畫幻覺。

I certainly don't want to assume they're always going to type a three-letter or a four-letter or a two-letter word I want some dynamism but that's fine because get string can get a string of any length, I can then use the string length function to just ask while the program is running how big is the string that I was handed?
當然我不能假設他總是,輸入3個字符或4個字符,或2個字符的單詞，我想要動態(tài)地分配,因為GetString可以獲得任意長度的字符串，然后我可以使用strlen函數(shù),來得到那個我傳遞的字符串,有多長？
