web-scraping

问题 In doing some scraping work I keep encountering the <tbody> tag in the Chrome DevTools inspector, but it doesn't appear in the source. For what I hope are obvious reasons, I find this super confusing. What's going on here? (I should also add that the html on this page is pretty malformed). For example, DevTools shows: <table> <tbody> <tr valign="top"> <td>...</td> Page source shows: <table border="0"> <tr valign="top"> <td> 回答1: The start tag for <tbody> is optional. That is, you can leave it

When I print the data scraped, I cant manually locate the table in the html either. Not sure what I'm doing wrong here. Once the data is imported, I need to populate a pandas dataframe to later use for graphing purposes, and export the data table

问题 I have searched a lot and a lot so as to find material about how to get meta data using XMLHTTP. And I think that's impossible to do that using the Early binding method. The only approach that will work is the late binding by CreateObject("HTMLFile") and dealing with that HTML which is late binding. The disadvantage of this approach is that it doesn't support the use of the QuerySelector or QuerySelectorAll .. Now I am trying to find alternative to this CSS selector .. without using the
