python - 查找并替换 POM 中两个单词之间的内容

Question

需要 bash 脚本或 python 脚本来查找和替换两个标签之间的文本？

例如:

<start>text to find and replace with the one I give as input<end>

'要查找并替换为我作为输入提供的文本'只是一个示例，它可能每次都不同。

我想做类似 ./changetxt inputfile.xxx newtext 的事情

其中 changetxt 有脚本； inputfile.xxx 包含需要更改的文本，newtext 是 inputfile.xxx 中的内容

Answer 1

python :

import sys

if __name__ == "__main__":
    #ajust these to your need
    starttag = "<foo>"
    endtag = "</foo>"

    inputfilename = sys.argv[1]
    outputfilename = inputfilename + ".out"
    replacestr = sys.argv[2]

    #open the inputfile from the first argument
    inputfile = open(inputfilename, 'r')
    #open an outputfile to put the result in
    outputfile = open(outputfilename, 'w')

    #test every line in the file for the starttag
    for line in inputfile:
        if starttag in line and endtag in line:
            #compose a new line with the replaced string
            newline = line[:line.find(starttag) + len(starttag)] + replacestr + line[line.find(endtag):]
            #and write the new line to the outputfile
            outputfile.write(newline)
        else:
            outputfile.write(line)
     outputfile.close()
     inputfile.close()

将其保存在 replacetext.py 文件中并以 python replacetext.py\path\to\inputfile "I want this text between the tags"运行
