python - 使用 Python 将 HTML 标记添加到文本中

问题描述

我在文件“File1”中有一个文本，其中包含以下文本：

-Accounting  
-HR

Some text  

-IT  
--Networks   
--Storage  
--DBA

我需要一段代码，它将逐行读取 File1 并用适当的 HTML 标记替换“-”和“--”，并将下面显示的最终结果保存在文本文件 File2 中

<ul>
<li>Accounting</li>
<li>HR</li>
</ul>

Some text

<ul><li>IT
       <ul>
          <li>Networks</li>
          <li>Storage</li>
          <li>DBA</li>
         </ul>
         </li></ul>

到目前为止，我尝试了下面的代码。

我将用于检查当前行是否包含“-”或“--”的两个布尔值最初设置为 False。如果当前行中有“-”或“--”，则代码在行首添加适当的标签，将布尔值更改为 True 并转到下一行。

现在布尔值用于查看上一行中是否有“-”或“--”，如果有破折号，它将在该行的开头添加适当的标签，该标签应该在上一行但我们已经在下一行这样。另一种方法是检查下一行是否以“-”或“--”开头，但我不知道该怎么做。当我使用 next() 时，该行被跳过。同时从两个文件中读取一个在前一行并检查它在下一行中的内容会是一个更好的解决方案吗？ 

    single_dash_prev_line = False
    double_dash_prev_line = False
    for line in File1:
        current_line = line

        if line[0] == "-":
            if line[1] != "-":
                if single_dash_prev_line == False:
                    new_line = "<ul><li>" + current_line[1:]
                    File2.write(new_line)
                    single_dash_prev_line = True
                elif single_dash_prev_line == True:
                    new_line = "</li><li>" + current_line[1:]
                    File2.write(new_line)
                    single_dash_prev_line = True


            elif line[1] == "-":
                if single_dash_prev_line == True:
                    new_line = "<ul><li>" + line[2:]
                    print(new_line)
                    File2.write(new_line)
                    double_dash_prev_line = True
                elif double_dash_prev_line == True:

        elif single_dash_prev_line == True:
            new_line = "</li></ul>" + current_line[1:]
            File2.write(new_line)
            single_dash_prev_line = False
        elif double_dash_prev_line == True:
            new_line = "</li></ul>" + current_line[1:]
            File2.write(new_line)
            single_dash_prev_line = False

        else:
            single_dash_prev_line = False
            double_dash_prev_line = False
            File2.write(current_line)

解决方案

下面的代码做了我需要的。

with open("finalfile.txt", 'w', encoding='utf-8') as File2, open("test.txt", "r", encoding='utf-8') as File1:
previous_line = ""
new_line = ""
double_dash_prev_line = False
single_dash_prev_line = False
for line in File1:
    current_line = line
    if line[0] == "-":
        if line[1] != "-":
            if single_dash_prev_line == False and double_dash_prev_line == False:
                new_line = "<ul><li> " + current_line[1:]
                File2.write(new_line)
                single_dash_prev_line = True
                double_dash_prev_line = False
            elif single_dash_prev_line == True:
                new_line = "</li><li> " + current_line[1:]
                File2.write(new_line)
                single_dash_prev_line = True
                double_dash_prev_line = False
            elif double_dash_prev_line == True:
                new_line = "</ul></li></ul><ul><li> " + current_line[1:]
                File2.write(new_line)
                single_dash_prev_line = True
                double_dash_prev_line = False


        elif line[1] == "-":
            if single_dash_prev_line == True:
                new_line = "<ul><li> " + line[2:]
                File2.write(new_line)
                double_dash_prev_line = True
                single_dash_prev_line = False
            elif double_dash_prev_line_line == True:
                new_line = "</li><li> " + line[2:]
                File2.write(new_line)
                double_dash_prev_line = True
                single_dash_prev_line = False
    elif single_dash_prev_line == True:
        new_line = "</li></ul> " + current_line[1:]
        File2.write(new_line)
        single_dash_prev_line = False
        double_dash_prev_line = False
    elif double_dash_prev_line_line == True:
        new_line = "</li></ul></ul> " + current_line[1:]
        File2.write(new_line)
        double_dash_prev_line = False
        single_dash_prev_line = False
    else:
        single_dash_prev_line = False
        double_dash_prev_line = False
        File2.write(current_line)
