Hi All,
I am trying to read an XML document which reference an entity resolver at the beginning and failed to open. The first few lines are as follows:
1. <?xml version="1.0" encoding="UTF-8"?>
2. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
3. <html xmlns="http://www.w3.org/1999/xhtml"; xmlns:html="http://www.w3.org/1999/xhtml";><head><script type="text/javascript">
.....
Below is the error output encountered:

On the other hand, it was possible to open it by removing the entity reference document on line 2. As a result, I would like to find out:
( i ) How to load an XML document without having to look up the DTD file which is of no use to me?
( ii ) Otherwise, how to come up with a local entity resolver to overcome this issue?
I am confused with different implementations of the few solutions available.
Many thanks,
Jack
