There is really no way to speed up a DOM parser except with a faster machine and more memory. As your file gets bigger and bigger, the DOM representation of your document will require more and more memory. That is why they came up with SAX and StAX.

NAME
tdom - tdom is an expat parser object extension to create an in-memory DOM tree from the input while parsing. SYNOPSIS
package require tdom set parser [expat] tdom $parser enable _________________________________________________________________ DESCRIPTION
tdom adds the C handler set "tdom" to an tcl expat parser obj. This handler set builds an in-memory DOM tree out of the input, parsed by the parser. A DOM tree created this way behave exactly like a DOM tree created by the "dom" command (see there). In fact, tdom is only another interface to the same functionality; it uses the code behind the dom code for building the DOM tree. tdom parserObj enable Adds the tdom C handler set to a Tcl expat parser object. Next time, the parser parses input, the tdom C handler functions create an in-memory DOM tree. tdom parserObj getdoc Returns the DOM tree as domDoc (see there) object. tdom parserObj setResultEncoding See the method setResultEncoding of the dom command. tdom parserObj setStoreLineColumn ?boolean? See the method setStoreLineColumn of the dom command. tdom parserObj remove Removes the tdom C handler set from the parser object. tdom parserObj keepEmpties See the option -keepEmpties of the dom command. tdom parserObj setExternalEntityResolver script SEE ALSO
