创建匹配的括号

本文介绍了创建匹配的括号-awk:sed的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个具有三种模式的数据集:

I have a data set that has three patterns:

第一:

abrasion abrade:stem<>ion:suffix abstainer abstain:stem<>er:suffix abstention abstain:stem<>ion:suffix

第二:

inaccurate in:prefix<>accurate:stem inactive in:prefix<>active:stem

第三:

incommunicable in:prefix<>communicate:stem<>able:suffix incompatibility in:prefix<>compatible:stem<>ity:suffix

我需要将以上形式转换为以下形式:匹配宾夕法尼亚州树银行的方括号( languagelog.ldc.upenn.edu/myl/PennTreebank1995.pdf )

I need to convert the above to following form : Matching the brackets in the way for Penn Tree Bank (languagelog.ldc.upenn.edu/myl/PennTreebank1995.pdf)

第一:

abrasion ((abrade:stem) ion:suffix) abstainer ((abstain:stem)er:suffix) abstention ((abstain:stem)ion:suffix)

第二:

inaccurate (in:prefix(accurate:stem)) inactive (in:prefix(active:stem))

第三:

incommunicable (in:prefix ((communicate:stem)able:suffix)) incompatibility (in:prefix ((compatible:stem)ity:suffix))

我正在工作的代码正在使用awk

The code, I am working is using awk

{ n = gsub(/<>/,")",$2) s = sprintf("%*s",n,"") gsub(/ /,"(",s) print "(" $1, s "((" $2 "))" }

更复杂的表格

nationalistic national: stem <>ism:suffix<>ist:suffix<>ic:suffix

收件人:

nationalistic ((((national: stem) ism:suffix)ist:suffix)ic:suffix)

没有产生示例中提到的预期输出.

It is not producing the expected outputs that mentioned in the examples.

推荐答案

这应该足够通用，因为它考虑了:stem，:prefix和:suffix进行匹配:

This should be general enough as it takes into account :stem, :prefix, and :suffix for matching:

awk 'BEGIN{FS=OFS="\n"}{ a=gensub(/([a-zA-Z]*):stem/,"(\\1:stem)", "g"); b=gensub(/(\([a-zA-Z]*:stem\))<>([a-zA-Z]*):suffix/,"(\\1\\2:suffix)", "g", a); c=gensub(/([a-zA-Z]*:prefix)<>(.*)/,"(\\1\\2)", "g", b); print c;}' testfile

这应该照顾多个后缀和前缀:

This should take care of multiple suffixes and prefixes:

awk 'BEGIN{FS=OFS="\n"}{ a=gensub(/([a-zA-Z]*):stem/,"(\\1:stem)", "g"); while ( a ~ /stem)<>.*:suffix/) { a=gensub(/(\([a-zA-Z]*:stem\).*?)<>([a-zA-Z]*):suffix/,"(\\1\\2:suffix)", "g", a); } while ( a ~ /<>/) { a=gensub(/([a-zA-Z]*?:prefix)<>(.*)/,"(\\1\\2)", "g", a); } print a;}' test
