Once you learn the (admittedly cryptic) syntax of regular expressions, you can transfer your expertise among tools, programming languages, and operating systems.
在编程中，正则表达式是用一种形式语言编写的，也称为regex或regexp。
In programming, a regular expression is written in a formal language, also known as regex or regexp.
正则表达式(regular expression,regexp)是用于描述字符串集的匹配模式的概念，在很多程序和语言中都是通用的。
The concept of regular expressions (regexps) -a notation for describing a pattern that matches a set of strings-is common across many programs and languages.
许多其他UNIX工具，包括交互式编辑器vi和Emacs、流编辑器sed 和awk，以及所有现代编程语言都支持正则表达式。
Many other UNIX tools, including interactive editors vi and Emacs, stream editors sed and awk, and all modern programming languages, also support regular expressions.
XSL转换语言的下一版本目前还处于开发和评审中，它包含了一个将正则表达式添加到该语言的提议。
The next version of the XSL transformation language, which is still under development and review, includes a proposal to add regular expressions to the language.
现有方法可能涉及根据词的词干或变音位构建正则表达式，以及其他搜索词的语言派生词。
Existing approaches might involve building a regular expression based on stems of a word, or metaphone, and other linguistic derivatives of a search term.
正则表达式基本上就是为进行文本处理而构建的一种小型的子语言，用来进行字符串的匹配和替换。
Regular expressions are basically a small sub-language built for text processing, used to match and replace strings of characters.
这三种语言都支持正则表达式和模式匹配。
Our three languages also share support for regular expressions and pattern matching.
用来实际处理正则表达式的语言并不是Perl，而是一种该领域特有的语言，Perl正好可以使用这种语言。
The language for doing a regular expression is not Perl; it is a domain-specific language that Perl happens to have a hook into.
我认为，Perl5的正则表达式的晦涩，也正是这门语言如此强大的原因之一，尽管它同时还相当难以维护。
In my opinion, the density of Perl 5's regular expressions is one of the reasons why the language is so powerful, while at the same time fairly hard to maintain.
如果已经在其它编程语言中使用正则表达式，那么Scala的应该不会让你感觉到惊讶。
Regexes in Scala should contain no surprises if you've used them in other programming languages.
正则表达式是几乎所有现代编程语言的共有特性之一，通常被简称为regexes（regex 的复数，Regular Expression 的简称）。
