I am using
dom4j-1.4-dev-8.jar, the version that came with my last maven build of
jelly.
My xml
document:
159
mbs
2,438,791
lines/tags -> 1 tag per line, all attributes
~6 attributes per
tag
4 out of 6
attributes are numeric values, so they are not huge strings.
Attributes 5 and 6
could probably be interned as well, but this would require additional api
support.
This document
expands to 1100mb's in memory. Could this be right? Seems high to me. I assume
all element names and attribute names are interned. I tried to force interning
by doing this:
SAXReader reader = new
SAXReader();
reader.setFeature("http://xml.org/sax/features/string-interning", true);
reader.setFeature("http://xml.org/sax/features/string-interning", true);
Which I think is
the default anyway. I am using xerces-2.0.2.jar for SAXReader via the system
property.
Are things being
interned? Are there any other tricks to reducing memory
consumption?
