#74 Incorrect XML -> JSON transformation

[aalmiray]

From the mailing list:

Hi,
I am trying to use json-lib 2.2.1 XMLSerializer.read(xmlString) to convert xml text to json, similar to org.json.XML.toJSONObject(xmlString).

I see at least the following things missing in the json generated by XMLSerializer:
1) the root element of the input xml is not included in the result json.
2) My input xml text which has nothing to do with json syntax, has multiple "<features>" nodes, all these nodes seems be omitted while conversion. I tried the options mentioned at http://sourceforge.net/tracker/index.php?func=detail&aid=1813520&group_id=171425&atid=857931 without luck.

I am I missing something with this relatively simple usecase? Thanks for the help.

Hi Andres,
This is what I tried, on jdk 1.4

<pre>
import org.json.JSONException;
import org.json.XML;
import net.sf.json.xml.XMLSerializer;

public class JsonTest {
public static void main(String[] args) {
String xmlStr ="<index><magazine>mag</magazine><issueDate /><promotions /><featureSet><features><sequence>1</sequence><style>set1</style><featuresHeader></featuresHeader><feature><style /></feature></features><features><sequence>2</sequence><style>set2</style><featuresHeader/><feature> <style /></feature><feature> <style /></feature><feature> <style /></feature></features><features><sequence>3</sequence><style>set2</style><featuresHeader/><feature> <style /></feature><feature> <style /></feature><feature> <style /></feature></features><features><sequence>4</sequence><style>set2</style><featuresHeader/><feature> <style /></feature><feature> <style /></feature><feature> <style /></feature></features></featureSet><relatedLinks /></index>";

XMLSerializer xmlSerializer = new XMLSerializer();
xmlSerializer.setForceTopLevelObject(true);
xmlSerializer.setTypeHintsCompatibility(false);
xmlSerializer.setTypeHintsEnabled(false);
xmlSerializer.setSkipWhitespace(true);

System.out.println("java.class.path: "+System.getProperty("java.class.path"));
System.out.println("xmlSerializer.read: "+xmlSerializer.read(xmlStr));

try {
System.out.println("XML.toJSONObject: "+XML.toJSONObject(xmlStr));
} catch (JSONException e) {
}
}
}
</pre>

Output:
java.class.path: C:\Documents and Settings\workspace\Temp\bin;I:\.maven\repository\ezmorph\jars\ezmorph-1.0.4.jar;I:\.maven\repository\commons-collections\jars\commons-collections-3.2.jar;I:\.maven\repository\json-lib\jars\json-lib-2.2.1.jar;I:\.maven\repository\xom\jars\xom-1.1.jar;I:\.maven\repository\commons-beanutils\jars\commons-beanutils-1.7.jar;I:\.maven\repository\commons-lang\jars\commons-lang-2.2.jar;I:\.maven\repository\commons-logging\jars\commons-logging-1.1.jar

Notice that <index> and <features> nodes are missing in the string generated by xmlSerializer.read.
