Reducing Lib Size ?

[Adam Horvath <Ad...@birdstep.com>]

Hello,
we are considering using Xerces, but the 1.9 MB Win32 Release build is a
bit to big. We will not use SAX nor Schemas, is there a straightforward
way to eliminate those from the library build. My first impression is
that it is not, but I hope that I am wrong.

To be more precise, both SAX and DOM parsers are built on top of a
low-level, SAX-like parser. As a result, SAX implementation is quite
thin so removing it won't give you much. XML Schema support, on the
other hand, can result in a more significant gain though it could
also be significantly more complicated to remove.

While there are implementations of XML scanners (that's where XML
Schema and DTD validation happens) that don't depend on XML Schema
support (e.g., DGXMLScanner and WFXMLScanner), there is also such
a thing as DOM type information which allows you to query XML Schema
grammar corresponding to the parsed DOM nodes.

Overall, I think it shouldn't be too difficult to get rid of XML Schema
support if you don't mind making some source code changes.

I don't know whether there's a good way to carve off sections of the
library, but I'm pretty sure the DOM parser is built on SAX, so removing
SAX would be an option only if you don't need to parse.
