Python將字符串的一部分寫入csv行

Question

我正嘗試在Python中將標記的所有匹配寫入csv文件。 我的字符串是：

<pre class="CodeRay highlight"><code data-lang="java"><span class="annotation">@CDIUI</span>(<span class="string"><span class="delimiter">"</span><span class="content">cdievents</span><span class="delimiter">"</span></span>) 
<span class="annotation">@Theme</span>(<span class="string"><span class="delimiter">"</span><span class="content">valo</span><span class="delimiter">"</span></span>) 
<span class="directive">public</span> <span class="type">class</span> <span class="class">CDIEventUI</span> <span class="directive">extends</span> UI { 
    <span class="annotation">@Inject</span> 
    InputPanel inputPanel; 

    <span class="annotation">@Inject</span> 
    DisplayPanel displayPanel; 

    <span class="annotation">@Override</span> 
    <span class="directive">protected</span> <span class="type">void</span> init(VaadinRequest request) { 
     Layout content = 
      <span class="keyword">new</span> HorizontalLayout(inputPanel, displayPanel); 
     setContent(content); 
    } 
}</code></pre> 

我寫命中一個CSV文件Python代碼是：

hits = soup.find_all("pre", "CodeRay highlight")# "programlisting") 
f = open('extractedsuorceTEST2.csv','ab') 
writer = csv.writer(f) 
writer.writerow(('page', hits[0].text.encode('UTF-8').replace('Â',' '))) 

通過這個代碼命中[0]：

'@CDIUI("cdievents")\n@Theme("valo")\npublic class CDIEventUI extends UI {\n @Inject\n InputPanel inputPanel;\n\n @Inject\n DisplayPanel displayPanel;\n\n @Override\n protected void init(VaadinRequest request) {\n  Layout content =\n   new HorizontalLayout(inputPanel, displayPanel);\n  setContent(content);\n }\n}' 

但結果用csv文件寫成：

@CDIUI(""cdievents"") 
@Theme(""valo"") 
public class CDIEventUI extends UI { 
    @Inject 
    InputPanel inputPanel; 

    @Inject 
    DisplayPanel displayPanel; 

    @Override 
    protected void init(VaadinRequest request) { 
     Layout content = 

當它應該是：

@CDIUI("cdievents") 
@Theme("valo") 
public class CDIEventUI extends UI { 
    @Inject 
    InputPanel inputPanel; 

    @Inject 
    DisplayPanel displayPanel; 

    @Override 
    protected void init(VaadinRequest request) { 
     Layout content = 
      new HorizontalLayout(inputPanel, displayPanel); 
     setContent(content); 
    } 
} 

任何人可以提出一個解決辦法？ 感謝

你必須要小心，不要只是放棄文件或CSVWriter對象。

試着改變你的代碼

hits = soup.find_all("pre", "CodeRay highlight")# "programlisting") 
with open('extractedsuorceTEST2.csv','ab') as f: 
    writer = csv.writer(f) 
    writer.writerow(('page', hits[0].text.encode('UTF-8').replace('Â',' '))) 

如果仍然失敗，請檢查field size limit並根據需要增加。
