如何用html寫書

原理：利用xml.etree.ElementTree對html進行決議和寫入

import xml.etree.ElementTree as ET  # 決議html、xml


def circle():
    print('輸入again回到程式開始處，輸入exit退出程式')
    tree = ET.parse('book.html')  # 決議檔案
    root = tree.getroot()  # 獲取根節點
    link_div = root.find('div[@id="link"]')  # 獲取link區的div節點，注意find和findall只能查找直接子元素
    body_div = root.find('div[@id="body"]')  # 獲取body區的div節點
    h1List = link_div.findall('div')
    count1 = 1
    for i in h1List:  # 列出所有h1標題
        print(str(count1) + '、' + i.find('h1').find('a').text)
        count1 += 1

    def create_h1():  # 創造h1節點
        h1_text = input('輸入章節名：')
        if h1_text == 'again':
            circle()
        elif h1_text == 'exit':
            print('program terminated!')
        else:
            h1_link_div = ET.Element('div')  # 創造節點
            h1_link_h1 = ET.Element('h1')
            h1_link_a = ET.Element('a')
            h1_link_a.text = h1_text
            h1_link_a.set('href', f'#{len(h1List) + 1}')  # 設定a節點的屬性
            h1_link_h1.append(h1_link_a)  # 懸掛節點
            h1_link_div.append(h1_link_h1)
            link_div.append(h1_link_div)  # 寫入link區
            h1_body_div = ET.Element('div')  # 創造節點
            h1_body_h1 = ET.Element('h1')
            h1_body_h1.text = h1_text
            h1_body_div.set('id', f'{len(h1List) + 1}')
            h1_body_div.append(h1_body_h1)
            body_div.append(h1_body_div)  # 寫入body區
            newTree = ET.ElementTree(root)  # root為修改后的root
            newTree.write('book.xml', encoding='utf-8')  # 重新寫入xml，進行更新，需要宣告編碼，否則寫入后會亂碼
            circle()

    def create_h2():  # 創造h2節點
        h2_text = input('輸入章節名：')
        if h2_text == 'again':
            circle()
        elif h2_text == 'exit':
            print('program terminated!')
        else:
            h2_link_div = ET.Element('div')
            h2_link_h2 = ET.Element('h2')
            h2_link_a = ET.Element('a')
            h2_link_a.text = h2_text
            h2_link_a.set('href', f'#{len(h1List)}_{len(h2List) + 1}')
            h2_link_h2.append(h2_link_a)
            h2_link_div.append(h2_link_h2)
            h1List[int(a) - 1].append(h2_link_div)
            h2_body_div = ET.Element('div')
            h2_body_h2 = ET.Element('h2')
            h2_body_h2.text = h2_text
            h2_body_div.set('id', f'{len(h1List)}_{len(h2List) + 1}')
            h2_body_div.append(h2_body_h2)
            body_div.findall('div')[int(a) - 1].append(h2_body_div)
            newTree = ET.ElementTree(root)
            newTree.write('book.xml', encoding='utf-8')
            circle()

    def create_statement():  # 創造h2下的內容
        p_text = input('輸入內容：')
        if p_text == 'again':
            circle()
        elif p_text == 'exit':
            print('program terminated!')
        else:
            p = ET.Element('p')
            p.text = p_text
            h2.append(p)
            newTree = ET.ElementTree(root)
            newTree.write('book.xml', encoding='utf-8')
            create_statement()

    print('在此處創建輸入0\n選擇章節輸入序號')
    a = input('輸入：')  # 輸入的為字串而非數字
    if a == '0':
        create_h1()
    else:
        h2List = link_div.findall('div')[int(a) - 1].findall('div')
        count2 = 1
        for i in h2List:  # 列出所有h2標題
            print(str(count2) + '、' + i.find('h2').find('a').text)
            count2 += 1
        print('在此處創建輸入0\n選擇章節輸入序號')
        b = input('輸入：')
        if b == '0':
            create_h2()
        else:
            h2 = body_div.findall('div')[int(a) - 1].findall('div')[int(b) - 1]  # 選擇的h2節點
            pList = h2.findall('p')  # 列出所有h2標題下的內容
            for i in pList:
                print(i.text)
            create_statement()
    tree = ET.ElementTree(root)  # root為修改后的root
    tree.write('book.html', encoding='utf-8')  # 重新寫入xml，進行更新，需要宣告編碼，否則寫入后會亂碼


circle()  # 回圈往復

注意千萬要仔細檢查，本人就是因為某個變數打錯字了，沒有發現，耽擱了很久……總之現在是順利地解決了
