我希望能够从 HTML 文件中提取链接到特定源的 URL答案

【问题标题】：I want to be able to extract the URLs linking to a particular source from an HTML file我希望能够从 HTML 文件中提取链接到特定源的 URL
【发布时间】：2019-07-24 10:52:52
【问题描述】：

这只是 HTML 文件的 sn-p。我希望能够提取那些链接开头的 URL：

https://post-phinf.pstatic.net

基本上，托管它的页面不会显示完整版本的图像，因为带宽限制，但它们在文件服务器上可用，因此如果更改图像名称，则可以提取完整分辨率图像。现在我通过使用批量图像下载器并仅修改浏览器本身中的 html 使其在过去工作，但有些图像不会保存完全丢失的部分，使它们无法使用，所以我想使用外部下载器来帮助我和它。

标签： html regex notepad++ extract

【解决方案1】：

老实说，Notepad++ 并不是在这里使用的最佳工具，因为它缺乏使用正则表达式模式迭代输入文本的能力。相反，我建议使用 Python 或 PHP 等脚本语言。这是使用 Python 的一种简单方法：

text = """<div class="se_component se_image default">
            <div class="se_sectionArea se_align-justify">
                <div class="se_editArea">
                    <div class="se_viewArea">
        <a href="#" onclick="return false;" class="se_mediaArea __se_image_link __se_link" data-linktype="img" data-linkdata="{&quot;imgId&quot; : &quot;SEDOC-1558061327644--611898955_image_9_img&quot;, &quot;src&quot; : &quot;https://post-phinf.pstatic.net/MjAxOTA1MTdfMjAw/MDAxNTU4MDYwNTAzMDUy.R5u9uY2pU6uLGQsjjFnkbPUAnpCdWBJYX269cflBTnAg.WHs50je9mpSiLf3RSIpSI4NwaXUCl9zI75By2rpIM4gg.JPEG/11.JPG&quot;, &quot;linkUse&quot; : &quot;false&quot;, &quot;link&quot; : &quot;&quot;}">
                            <img id="SEDOC-1558061327644--611898955_image_9_img" class="se_mediaImage __se_img_el" a href="https://post-phinf.pstatic.net/MjAxOTA1MTdfMjAw/MDAxNTU4MDYwNTAzMDUy.R5u9uY2pU6uLGQsjjFnkbPUAnpCdWBJYX269cflBTnAg.WHs50je9mpSiLf3RSIpSI4NwaXUCl9zI75By2rpIM4gg.JPEG/11.JPG" data-a href="https://post-phinf.pstatic.net/MjAxOTA1MTdfMjAw/MDAxNTU4MDYwNTAzMDUy.R5u9uY2pU6uLGQsjjFnkbPUAnpCdWBJYX269cflBTnAg.WHs50je9mpSiLf3RSIpSI4NwaXUCl9zI75By2rpIM4gg.JPEG/11.JPG" data-attachment-id="IlIwLZR377zNeHwU5KXqKxLOAZPI" alt="" width="4000" height="6000">

        </div>
        THE REST OF YOUR TEXT HERE..."""

matches = re.findall(r'https://post-phinf\.pstatic\.net[^"&? ]+', text)
print(matches)

打印出来：

https://post-phinf.pstatic.net/MjAxOTA1MTdfMjAw/MDAxNTU4MDYwNTAzMDUy.R5u9uY2pU6uLGQsjjFnkbPUAnpCdWBJYX269cflBTnAg.WHs50je9mpSiLf3RSIpSI4NwaXUCl9zI75By2rpIM4gg.JPEG/11.JPG

以及大约十几个其他 URL。

是否有它的版本，我们只是传递文件。您的代码也给出了未定义的错误
在脚本顶部添加import re。
