python：将xml子元素添加到父元素文本的子字符串中

【问题标题】：python: adding an xml sub-element to a substring of a parent element's textpython：将xml子元素添加到父元素文本的子字符串中
【发布时间】：2020-03-19 03:56:33
【问题描述】：

假设我有一个包含文本的 XML 元素，并且我想为某些单词添加子元素。例如转换：

<s>I don't want to have to entertain every Tom, Dick, and Harry who comes through here.</s>

到

<s>I don't want to have to entertain every <name nid="n1">Tom</name>, <name nid="n2">Dick</name>, and <name nid="n3">Harry</name> who comes through here.</s>

我有一个需要包装的所有字符串的列表，我可以很容易地在文本字符串中找到它们的位置，但我不知道如何在特定位置添加标签（除了构建通过使用字符串操作来完成整个事情）。使用 ElementTree 或 BeautifulSoup 肯定有更好的方法吗？

【解决方案1】：

我认为这应该至少能让你大部分时间到达你想去的地方：

    from bs4 import BeautifulSoup as bs

    old = """
    <s>I don't want to have to entertain every Tom, Dick, and Harry who comes through here.</s>
    """
    names = ["Tom", "Dick", "Harry"]

    soup = bs(old,'lxml')
    orig_tag = soup.s
    old_st_lst = orig_tag.string.split(' ')
    new_st_lst = []
    for ns in old_st_lst:
        t_ns = ns.replace(',','')    
        if t_ns in names:
            place = names.index(t_ns)+1
            new_el = f'<name nid="n{place}">{ns}</name>'
            new_st_lst.append(new_el)        

        else:
            new_st_lst.append(ns)    
    final = ' '.join(new_st_lst)    

    for item in soup.select('s'):
        item.string = final

    print(soup.text)

输出：

I don't want to have to entertain every <name nid="n1">Tom,</name> <name nid="n2">Dick,</name> and <name nid="n3">Harry</name> who comes through here.
