<h2 id="code">使用 Python 编辑 HTML - 代码示例</h2>
<p>现在,让我们开始动手编写一些 Python 代码来编辑网页。我们先来解释一下步骤。</p>
<p>步骤:</p>
<ul>
<li><strong>通过初始化HTMLDocument</strong>类的对象来加载现有的 HTML 文件。</li>
<li>通过 ID 访问段落并更新段落文本。</li>
<li>通过调用<strong>create_element</strong>函数创建新段落。</li>
<li>创建图像元素并设置属性。</li>
<li>创建一个简单的 HTML 表并添加行和单元格。</li>
<li>调用<strong>get_elements_by_tag_name</strong>方法来访问<head>标签并添加<meta>。</li>
<li>通过调用保存方法保存修改后的 HTML 。</li>
</ul>
<p>您可以按照下面给出的代码片段进行操作:</p>
<pre class="prettyprint lang-py highlighter-hljs"><code>import os
import aspose.html as html
# Set up paths for working files.
output_dir = "files"
input_file = os.path.join(output_dir, "existing.html")
output_file = os.path.join(output_dir, "modified.html")
# Apply Aspose License
license = html.License()
license.set_license("License.lic")
# Load the existing HTML file by initializing an object of the HTMLDocument class.
document = html.HTMLDocument(input_file)
# Change document title
document.title = "New Title"
# Access the paragraph by ID and update paragraph text.
paragraph = document.get_element_by_id("intro")
if paragraph:
paragraph.text_content = "This paragraph has been updated using Aspose.HTML!"
# Create new paragraph by calling the create_element function.
new_paragraph = document.create_element("p")
new_paragraph.text_content = "This is a new paragraph added via Aspose.HTML for Python."
# Create an image element and set the attributes.
image = document.create_element("img")
image.set_attribute("src", "https://www.w3schools.com/html/img_chania.jpg")# Working URL
image.set_attribute("alt", "Chania")
# Create a simple HTML table.
table = document.create_element("table")
table.set_attribute("border", "1")# Visible table borders
table.set_attribute("width", "50%")
# Add rows and cells manually
for i in range(3):
row = document.create_element("tr")
for j in range(3):
cell = document.create_element("td")
cell.text_content = f"Row {i+1}, Col {j+1}"
row.append_child(cell)
table.append_child(row)
# === Access <body> and add all new content ===
body_elements = document.get_elements_by_tag_name("body")
if body_elements.length > 0:
body = body_elements
# Set background color using pure HTML
body.set_attribute("bgcolor", "#f0f0f0")
# Append new elements
body.append_child(new_paragraph)
body.append_child(image)
body.append_child(table)
# Invoke the get_elements_by_tag_name method to access <head> tag and add <meta>.
head_elements = document.get_elements_by_tag_name("head")
if head_elements.length > 0:
head = head_elements
meta = document.create_element("meta")
meta.set_attribute("name", "description")
meta.set_attribute("content", "This is a sample HTML document with an image and table.")
head.append_child(meta)
# Save the modified HTML by calling the save method.
document.save(output_file)
printf("HTML modified and saved to: {output_file}")</code></pre>
<p>输出:</p>
