Resolving html entities with NSXMLParser on iPhone

Question

I think I read every single web page relating to this problem but I still cannot find a solution to it, so here I am.

I have an HTML web page which is not under my co

A possibly less hacky solution is replace the DTD with a local modified one with all external entity declaration replaced with local one.

This is how I do it:

First, find and replace the document DTD declaration with a local file. For example, replace this:

hi!
Hello

with this:

hi!
Hello

```

Download the DTD from the W3C URL and add it to your app bundle. You can find the path of the file with following code:

NSBundle* bundle = [NSBundle bundleForClass:[self class]];
NSString* path = [[bundle URLForResource:@"xhtml1-transitional" withExtension:@"dtd"] absoluteString];

Open the DTD file, find any external entity reference:

%HTMLlat1;      

replace it with the content of the entity file ( http://www.w3.org/TR/xhtml1/DTD/xhtml-lat1.ent in the above case)

After replacing all external reference, NSXMLParser should properly handle the entities without the need to download every remote DTD/external entities each time it parse a XML file.
