使用 Python 识别莎士比亚的 XML 编码戏剧中的行指向哪个字符

Question

我是 Python 的新手，我正在使用 Python 提取莎士比亚戏剧中某些角色所说的台词。 我用的是一个罗密欧与朱丽叶的XML文件，基本上是这样写的：

<PLAY>
    ...
    <SPEECH>
    <SPEAKER>JULIET</SPEAKER>
    <LINE>Yon light is not day-light, I know it, I:</LINE>
    <LINE>It is some meteor that the sun exhales,</LINE>
    <LINE>To be to thee this night a torch-bearer,</LINE>
    <LINE>And light thee on thy way to Mantua:</LINE>
    <LINE>Therefore stay yet; thou need'st not to be gone.</LINE>
    </SPEECH>
    

    <SPEECH>
    <SPEAKER>ROMEO</SPEAKER>
    <LINE>Let me be ta'en, let me be put to death;</LINE>
    <LINE>I am content, so thou wilt have it so.</LINE>
    <LINE>I'll say yon grey is not the morning's eye,</LINE>
    <LINE>'Tis but the pale reflex of Cynthia's brow;</LINE>
    <LINE>Nor that is not the lark, whose notes do beat</LINE>
    <LINE>The vaulty heaven so high above our heads:</LINE>
    <LINE>I have more care to stay than will to go:</LINE>
    <LINE>Come, death, and welcome! Juliet wills it so.</LINE>
    <LINE>How is't, my soul? let's talk; it is not day.</LINE>
    </SPEECH>
    
    <SPEECH>
    <SPEAKER>JULIET</SPEAKER>
    <LINE>It is, it is: hie hence, be gone, away!</LINE>
    <LINE>It is the lark that sings so out of tune,</LINE>
    <LINE>Straining harsh discords and unpleasing sharps.</LINE>
    <LINE>Some say the lark makes sweet division;</LINE>
    <LINE>This doth not so, for she divideth us:</LINE>
    <LINE>Some say the lark and loathed toad change eyes,</LINE>
    <LINE>O, now I would they had changed voices too!</LINE>
    <LINE>Since arm from arm that voice doth us affray,</LINE>
    <LINE>Hunting thee hence with hunt's-up to the day,</LINE>
    <LINE>O, now be gone; more light and light it grows.</LINE>
    </SPEECH>
    
    <SPEECH>
    <SPEAKER>ROMEO</SPEAKER>
    <LINE>More light and light; more dark and dark our woes!</LINE>
    </SPEECH>
    ...
</PLAY>

整个文件也可以在这里找到。

我所做的假设是一条线指向之前直接说话的角色。 例如，我假设这段文字的最后一行（'更多光明和光明-更黑暗和黑暗我们的困境。'）是针对朱丽叶的。

我正在尝试使用正则表达式提取罗密欧所说的所有针对朱丽叶的台词。 这是我到目前为止的代码：

def get_dialogue(character_name, transcript):
    
    character_lines = []
   
    character_name_pattern = character_name
   
    # Iterate over a tag’s siblings and append text to 'character_lines'.
    for line in Bs_data.find_all('SPEAKER', string = character_name_pattern):
        for sib in line.next_siblings:
            if sib.name == 'LINE':
                character_lines.append(sib.get_text())
       
    character_lines = ''.join(character_lines)      
    return character_lines

get_dialogue("ROMEO", Bs_data)

但是，这只会返回罗密欧所说的所有台词，而不仅仅是朱丽叶所说的台词。

我一直在试图弄清楚该怎么做，但我无法弄清楚我的下一步应该是什么。 如果有人有提示可以为我指明正确的方向，我们将不胜感激！
