如何在tcl中使用正则表达式从单词中删除括号

Question

Hi I am trying to remove the brackets from a word like NAND[0] and I want the result to be NAND0. How do I code using regexp in Tcl.

Answer 1

Assuming the data from which you want to strip the brackets is in the variable val and have the transformed data stored in variable result

set result [regsub -all {\[|\]} $val ""]

You can also do

regsub -all {\[|\]} $val "" result
