查找和替換POM中兩個單詞之間的內容

Question

需要使用bash腳本或python腳本來查找和替換兩個標籤之間的文本？

E.g：

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

「文本發現，並與一個我給輸入替換」僅僅是一個例子，它可以改變每一次。

我要像做./changetxt inputfile.xxx newtext

其中changetxt有腳本; inputfile.xxx有需要改變文字和newtext就是進入inputfile.xxx

蟒蛇：

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() 

這個保存在replacetext.py文件並運行爲蟒蛇replacetext.py \路徑\到\ inputfile中「我想要的標籤之間的這段文字」

您也可以使用BeautifulSoup這一點，從他們的文檔：

如果您設置一個標籤的.string屬性，日Ë標籤的內容被替換 用你給的字符串：

markup = '<a href="http://example.com/">I linked to <i>example.com</i></a>' 
soup = BeautifulSoup(markup) 

tag = soup.a 
tag.string = "New link text." 
tag 
# <a href="http://example.com/">New link text.</a>
