Web scraping issue - HTML code scraped in VBA differs from source code in the website

Hi everyone,

I got an issue with web scraping with this website (http://www.hkexnews.hk/sdw/search/search_sdw.asp).

I found that the code scrapped from the web by the VBA procedure is different from that shown on Chrome (they are the same in the past so that the procedure works). I wonder whether this issue relates to the language of javascript. Can anyone help me?
Thanks in advance
