Hello everyone,
I'm trying to parse a very large XML file using SAX with the XML package
(i.e., mainly the xmlEventParsing function). This function takes as an
argument a list of other functions (handlers) that will be called to handle
particular xml nodes.
If when I use Rprof(), all the handler functions are lumped together under
the <anonymous> label, and I get something like this:
$by.total
total.time total.pct self.time self.pct
"system.time" 151.22 99.99 0.00 0.00
"MyParsingFunction" 149.38 98.77 0.00 0.00
"xmlEventParse" 149.38 98.77 0.00 0.00
".Call" 149.32 98.73 3.04 2.01
"<Anonymous>" 146.74 97.02 141.26 93.40 <---
!!
"xmlValue" 3.04 2.01 0.46 0.30
"xmlValue.XMLInternalNode" 2.58 1.71 0.14 0.09
"standardGeneric" 2.12 1.40 0.50 0.33
"gc" 1.86 1.23 1.86 1.23
...
Is there a way to make Rprof() identify the different handler functions, so
I can know which one might be a bottleneck? Is there another profiling tool
that would be more appropriate in a case like this?
Thank you very much for your help!
Frederic
