I have a problem with parsing XML file. It structure looks like:
<?xml version="1.0" encoding="UTF-8"?>
<teryt>
<catalog name="TERC" type="all" date="2014-01-01">
<row>
<col name="WOJ">02</col>
<col name="POW"/>
<col name="GMI"/>
<col name="RODZ"/>
<col name="NAZWA">DOLNOŚLĄSKIE</col>
<col name="NAZDOD">województwo</col>
<col name="STAN_NA">2014-01-01</col>
</row>
<row>
<col name="WOJ">02</col>
<col name="POW">01</col>
<col name="GMI"/>
<col name="RODZ"/>
<col name="NAZWA">bolesławiecki</col>
<col name="NAZDOD">powiat</col>
<col name="STAN_NA">2014-01-01</col>
</row>
...
</catalog
</teryt>
I have parser right now but it only read file to the one variable. My parser code.

How can I have every single attribute (WOJ, POW, NAZWA etc.) in a single variable ?
This is how you can do...

parser.getAreaXml();
}
public void getAreaXml() {
final List<StringBuilder> first = new ArrayList<StringBuilder>();
try {
SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
SAXParser saxParser = saxParserFactory.newSAXParser();
DefaultHandler defaultHandler = new DefaultHandler() {
Boolean wojTag = false;
Boolean powTag = false;

public void startElement(String uri, String localName,

}
}
public void characters(char ch[], int start, int length)
throws SAXException {

temp.append(" ");
}

}

}
if (stan_naTag.equals(true)) {
temp.append(new String(ch, start, length));
temp.append(" ");
}
first.add(temp);
}
public void endElement(String uri, String localName,

}
if (qName.equalsIgnoreCase("col")) {

}
if (qName.equalsIgnoreCase("col")) {
gmiTag = false;
}
if (qName.equalsIgnoreCase("col")) {
rodzTag = false;
}
if (qName.equalsIgnoreCase("col")) {
nazwaTag = false;
}
if (qName.equalsIgnoreCase("col")) {
nazdodTag = false;
}
if (qName.equalsIgnoreCase("col")) {
stan_naTag = false;
}
}
};
saxParser.parse("E:/ResourcePDF/zippertest/src/test.xml",
defaultHandler);
for (StringBuilder s : first) {
System.out.print(s);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
out put will be like this for above xml file
02 DOLNO?L?SKIE województwo 2014-01-01 02 01 boles?awiecki powiat 2014-01-01
