我正在构建 HTML 作为一个更大项目的一部分。建筑工程，没有问题。但是我担心代码太冗长或者我没有使用 BeautifulSoup 的全部功能。
例如:我正在生成一个 div类(class)标签editorial包装了一个 div类(class)editorial-title , editorial-image , editorial-subtitle , editorial-article以该顺序。
示例 HTML-
<div class="editorial">
<div class="editorial-title">Hello</div>
<div class="editorial-image"><img src="https://images.dog.ceo/breeds/collie-border/n02106166_2595.jpg"></div>
<div class="editorial-subtitle">world</div>
<div class="editorial-article">Yeah. But Parasite? It should have been Gone with the Wind!</div>
</div>
这是适用于我正在尝试做的小型演示版本的长代码 -
from bs4 import BeautifulSoup
title = "Hello"
subtitle = "world"
image_url = "https://images.dog.ceo/breeds/collie-border/n02106166_2595.jpg"
article = "But Parasite? It should have been Gone with the Wind!"
editorial_container = BeautifulSoup('', 'html.parser')
editorial_container_soup = editorial_container.new_tag('div', attrs={"class": "editorial"})
editorial_soup = BeautifulSoup('', 'html.parser')
editorial_title = editorial_soup.new_tag('div', attrs={"class": "editorial-title"})
editorial_image = editorial_soup.new_tag('div', attrs={"class": "editorial-image"})
image = editorial_soup.new_tag('img', src=image_url)
editorial_subtitle = editorial_soup.new_tag('div', attrs={"class": "editorial-subtitle"})
editorial_article = editorial_soup.new_tag('div', attrs={"class": "editorial-article"})
editorial_title.append(title)
editorial_image.append(image)
editorial_subtitle.append(subtitle)
editorial_article.append(article)
editorial_soup.append(editorial_title)
editorial_soup.append(editorial_image)
editorial_soup.append(editorial_subtitle)
editorial_soup.append(editorial_article)
editorial_container_soup.append(editorial_soup)
editorial_container.append(editorial_container_soup)
print(editorial_container.prettify())
它可以完成工作，但我觉得它太长了。有没有更优雅的方法来实现这一目标？
最佳答案
对于您正在执行的任务，我强烈考虑使用 Jinja模板而不是 BeautifulSoup。
如果你使用 Jinja，你只需要将带有编辑信息的字典传递给 editorial.html看起来像这样:
<!-- reusable editorial.html -->
<div class="editorial">
<div class="editorial-title">{{ title }}</div>
<div class="editorial-image"><img src="{{ image }}"></div>
<div class="editorial-subtitle">{{ subtitle }}</div>
<div class="editorial-article">{{ article }}</div>
</div>
包括
editorial.html在下面的 html 文件中，它会被 flask 加载。在此示例中，这将用作您的基本模板。<!-- template.html -->
<html>
<head>
<title>Jinja Sample</title>
</head>
<body>
{% include "editorial.html" %}
</body>
</html>
使用 Flask
启动一个flask应用程序，如下所示:
from flask import Flask, render_template
app = Flask(__name__)
@app.route("/")
def editorial_test():
editorial_info = {
"title" : "Hello",
"image" : "https://images.dog.ceo/breeds/collie-border/n02106166_2595.jpg",
"subtitle" : "world",
"article" : "Yeah. But Parasite? It should have been Gone with the Wind!"
}
return render_template('template.html', editorial=editorial_info)
if __name__ == '__main__':
app.run(debug=True)
我没有测试上面的代码。看看这个优秀的tutorial进一步澄清。
直接渲染文件
如果你不想使用 Flask，你可以像这样直接渲染网页(我假设所有文件都在同一个目录中):
import jinja2
editorial_info = {
"title" : "Hello",
"image" : "https://images.dog.ceo/breeds/collie-border/n02106166_2595.jpg",
"subtitle" : "world",
"article" : "Yeah. But Parasite? It should have been Gone with the Wind!"
}
templateLoader = jinja2.FileSystemLoader(searchpath="./")
templateEnv = jinja2.Environment(loader=templateLoader)
TEMPLATE_FILE = "template.html"
template = templateEnv.get_template(TEMPLATE_FILE)
outputText = template.render(editorial_info)
print(outputText)
输出
<html>
<head>
<title>Jinja Sample</title>
</head>
<body>
<div class="editorial">
<div class="editorial-title">Hello</div>
<div class="editorial-image"><img src="https://images.dog.ceo/breeds/collie-border/n02106166_2595.jpg"></div>
<div class="editorial-subtitle">world</div>
<div class="editorial-article">Yeah. But Parasite? It should have been Gone with the Wind!</div>
</div>
</body>
</html>
关于python - 是否有更短的方法或 pythonic 方法来生成遵循使用 BeautifulSoup 模式的自定义 html？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60350625/
