Invalid XML2JSON conversion of bitmask with a leading 1

[mhmarkushuber]

We are using the following XML to JSON conversion in our code bases.

private JSONObject xmlToJson() throws Exception {
        JSONObject jsonObj = null;
        FileReader fr = new FileReader(benchmarkXmlFile); // Reads the XML file (data.xml)
        jsonObj = XML.toJSONObject(fr); // Performs the conversion using org.json.XML
        fr.close();
        return jsonObj;
    }

The XML file contains a bitmask

<ProcessAffinity>
          <Ranks>
            <Rank>0</Rank>
            <Mask>1000000000000000000000000000000000000000000000000000</Mask>
          </Ranks>
</ProcessAffinity>

This bit mask is converted to a floating point number in JSON, only if it has a leading "1" otherwise the conversion is valid:

Hi @mhmarkushuber thanks for bringing up this issue. XMLParserConfiguration is available to customize XML parsing. Will this work for you?

        String str = "<ProcessAffinity>\n" +
                "          <Ranks>\n" +
                "            <Rank>0</Rank>\n" +
                "            <Mask0>0000000000000000000000000000000000000000000000000000</Mask0>\n" +
                "            <Mask1>1000000000000000000000000000000000000000000000000000</Mask1>\n" +
                "          </Ranks>\n" +
                "</ProcessAffinity>";

        JSONObject jsonObject = XML.toJSONObject(str, new XMLParserConfiguration().withKeepStrings(true));
        System.out.println(jsonObject.toString(2));

Output:

{
    "ProcessAffinity": {
        "Ranks": {
            "Rank": "0",
            "Mask0": "0000000000000000000000000000000000000000000000000000",
            "Mask1": "1000000000000000000000000000000000000000000000000000"
        }
    }
}

Thank you. We need to double-check in our code-base but this seems to be what we anticipate
