A stupid speed test is supplied in
bench.js. We measure how many
25-byte elements a SAX parser can process:
- libxmljs (libxml2 binding): 77,000 el/s
- node-expat (libexpat binding, this): 113,000 el/s
These numbers were recorded on a Core 2 2400 MHz and may turn out to be bullshit, given my few node.js experience.
node-waf configure node-waf build
For using the library, make sure
build/default/expat.node is in
Important events emitted by a parser:
There are more. Use
test.js for reference.
It's possible to stop and resume the parser from within element handlers using the parsers stop() and resume() methods.
We don't emit an error event because libexpat doesn't use a callback
either. Instead, check that
true. A descriptive
string can be obtained via
getError() to provide user feedback.
A word about special parsing of xmlns: this is not neccessary in a bare SAX parser like this, given that the DOM replacement you are using (if any) is not relevant to the parser.
