xPE | Simple library to handle PE files

Your XML is fine, actually it's quite small, and loads very quickly, with the proper document settings.

I did notice the DTD, which is re-downloaded from http://patents.ic.gc.ca/cipo/dtd/ca-patent-document-v2-0.dtd every time you download a file. Moreover, the DTD itself embeds other DTD files, so you're likely downloading them too.

MSXML XML does a lot of extra stuff by default, but if your XML is known to be "good", then the fastest way to load it is to set the following values to false before calling Load(). This way you're only validating that the XML is well formed.

you try to hide "No results found !" inside for but you don't stop for loop when something has fined

You seem to want a list of books that match a certain criteria. In that case you just want to use the following XPath:

I manually deobfuscated it and got this (variable names mine):
