从aspx页面解析动态生成的URL

标签： python asp.net python-3.x parsing

我正在尝试解析包含表格的aspx页面， 每行都有一个元素，可在新选项卡上打开pdf文件。

该元素打开的url以页面源中的形式存储在脚本内，但是似乎只有在您实际单击该元素之后才会为每个文件生成脚本。

我的最终目标是保存所有这些pdf文件，我认为最好的解决方案是保存url并使用请求保存每个url的内容。 但是，如果不实际单击每个元素，我找不到一种获取所有网址的方法。

单击元素后脚本的HTML：

 <script language="JavaScript">
    var docUrl=escape('/NGCS.Web.Secured/Viewer/NGCSViewerPage.aspx?DocumentNumber=4105ea67709148d7984ce9a2efc48157');
    window.open(unescape(docUrl)); </script>

此示例中的所需值是'docUrl'中列出的字符串，即：'/ NGCS.Web.Secured / Viewer / NGCSViewerPage.aspx？DocumentNumber = 4105ea67709148d7984ce9ce2e9a2efc48157'，或字符串中的'DocumentNumber' ，即：“ 4105ea67709148d7984ce9a2efc48157”。

这些值中的任何一个都可用于导航到包含所需文件的页面的动态URL。

找不到与我的问题类似的东西。

您没有提供太多有关如何持有该对象的信息，因此我将假定其为字符串。 您可以使用正则表达式来获取文档编号，如下所示：
