Sax parse xml bug , I can't figure it out!

Question

(1) orginal xml file as followings:
<row>
<field name="productBundleId">22456</field>
<field name="localPath">/products/01092008/RealArcade/STD_StonesOfKhufu_NOK6030_EN_v1_0_12.jar</field>
<field name="description">/products/01092008/RealArcade/STD_StonesOfKhufu_NOK6030_EN_v1_0_12.jad</field>
</row>
(2) task parsing the above and and retrieve the value and set it to a javabean:
(3) Using the SAX as the xml file is very big , about 1M

                    m_jad = false;
     @Override
     public void ignorableWhitespace(char[] ch, int start, int length) throws SAXException
          m_whitespace = new String(ch, start, length);
(4) please pay attention to the bold area , the method:
character()
I declare a variable "m_character" to decide if the parser don't read content of
an item in above xml file ,such as
/products/01092008/RealArcade/STD_StonesOfKhufu_NOK6030_EN_v1_0_12.jar
(5)error:
but some time it only reads part of the character contents:
eg:
/products/01092008/RealAr
cade/STD_StonesOfKhufu_UnitedStates_LGCU515_EN_v1_0_12.jad
It means that they parser comes across some character when parsing,
but in fact it doesn't.
You can use println() to monitor the outputs.
So I need to declare some boolean variable to decide whether all the content of one item has read fully.
(6)
May be its a bug, my xml file don't include any special charactor.

Answer 1

The problem is that the character data might be delivered in multiple chunks, this means that the characters method might be called more than once for the same element.
One way around this is to create a StringBuilder or something similar in the startElement() method, and fill it with the characters in the characters() method and read it in the endElement() method.
