Subject: Memory used when parsing an xml file...
I am using Xerces 1.6.0 and find that quite a bit of memory is used and
retained when parsing an xml file.
The file I am using is about 500 Kbytes and running a short program that
only
parses the file the memory usage is about 12 MBytes. �This is in release
mode
and i need use DOM (IDOM).
Does this seem correct? �Should I be expected much greater memory
efficiency?
Does it make a difference with the depth of the elements in the tree?
The simple program I wrote to test this is as follows.
� � � � � � � � parser = new IDOMParser;
� � � � � � � � parser->setIncludeIgnorableWhitespace(false);
� � � � � � � � parser->setCreateEntityReferenceNodes(false);
� � � � � � � � //parser->setValidationConstrainFatal(true);
� � � � � � � � parser->setDoSchema(false);
� � � � � � � � parser->setValidationScheme(IDOMParser::Val_Auto);
� � � � � � � � parser->setValidationSchemaFullChecking(false);
� � � � � � � � parser->setDoNamespaces(false);
� � � � � � � � const char* xmlFile = "prefixos.xml";
� � � � � � � � parser->parse(xmlFile);
XML file example:
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE tarifador [
<!ELEMENT tarifador (prefixos+)>
<!ATTLIST tarifador
versao CDATA #REQUIRED>
<!ELEMENT prefixos (p+)>
<!ATTLIST prefixos
area_tar_origem CDATA #REQUIRED>

...
... 18.000 elements
...
<p ID="P11209" r="3"/>
<p ID="P11215" r="3" c="S"/>
</prefixos>
</tarifador>
Thanks in advance.
