Hi,
You could apply a convention here, like in CamelCaseStyle you can say
new CamelCase(false, false)
Which will convert PersonName to personName. However, as the XML specification implies, XML is case sensitive, which means PersonName is not equal to personName as an element. Also you may notice in the CamelCaseStyle the setElement and setAttribute methods, this allows for various alternatives. For example
camelCase.setElement("PersonName", "personName")
camelCase.setElement("personname", "personName")
etc..
Case insensitivity is not supported because is not really valid XML.

Hello.
I am still having a problem getting inconsistent cased xml to deserialize. I would really appreciate your help.
For example, in the code below, the SampleObject has a "personName" member variable. When the test code passes in "PersonName" the object cannot deserialize.
One solution that will work every time is to use a Style as I have done below, which will accept "personname" in the xml.
The problem is that using a style means that the xml ALWAYS has to be lowercase. This means that while "personname" will be deserialize, "PersonName" or "personName" will not.
Question: How do I make the Persister deserialize any case? Using the Style and Format alone does not work.
Thanks!

Persister serializer = new Persister(format);
SampleObject output;
try
{
output = (SampleObject)serializer.read(SampleObject.class, withUppercase);

throw new RuntimeException("failed to deserialize as stream", e);

Hi,
I was unable to find a test case so I have created my own and included it below.
The xml has "Name" as the attribute, but the class has "name" with lowercase n.
I expect that my Style implementation will cause the framework to succeed in deserializing, but it fails.
Can you kindly suggest the appropriate use of the Style object to achieve my desired effect of case insensitivity?
Thanks!

Hi,
You can set the style in the Format object, and pass that to the persister. I think there is actually a test case available with the download that has an example of case insensitive deserialization.

I agree that the Style class could work, but the Persister class does not allow me to set a Style.
How do I use a Style in the deserialization process?
Thanks,
Greg
