Python Scrapy获取HTML <script> tag

Question

我有一个项目，我需要HTML代码中的get脚本。

        <script>
      (function() {
        ... / More Code
        Level.grade = "2";

        Level.level = "1";

        Level.max_line = "5";

        Level.cozum = 'adım 12\ndön sağ\nadım 13\ndön sol\nadım 11'; 
... / More Code
</script>

我如何仅获得“adım12 \\ndönsağ\\nadım13 \\ndönsol \\nadım11”此代码？

感谢您的帮助

使用正则表达式来做到这一点

首先抓取该SCRIPT标签的内容，例如

response.css("script").extract_first()

然后使用这个正则表达式

(Level\.cozum = )(.*?)(\;)

在此处查看演示https://regex101.com/r/YxHRmR/1

这是代码

import re
regex = r"(Level\.cozum = )(.*?)(\;)"

test_str = ("<script>\n"
    "      (function() {\n"
    "        ... / More Code\n"
    "        Level.grade = \"2\";\n\n"
    "        Level.level = \"1\";\n\n"
    "        Level.max_line = \"5\";\n\n"
    "        Level.cozum = 'adım 12\\ndön sağ\\nadım 13\\ndön sol\\nadım 11'; \n"
    "... / More Code\n"
    "</script>")

matches = re.findall(regex, test_str, re.MULTILINE)

print(matches)
