You're using the Table class to parse a table (which admittedly sounds
reasonable :). It's complaining that it expects column or constraint,
NOT table.
I.e. you need to parse from a level up - try using
Application.Factory.parse() instead of Table.Factory.parse()

Hello,
Sorry, but I am new to XmlBeans, so please bear with me.
We would like to take a fragment of xml, pass it to the appropriate
generated XmlBean factory’s parse() method, get back a new generated
XmlBean object, and then use its API to get values of attributes,
children generated XmlBean objects. Etc.
I pass the xml fragment to the generated XmlBeans object factory class’s
parse() method and get back my generated XmlBean object.
I then call “getName()” on it to get the “name” attribute value from it,
but the value is null.
I added a “validate()” call on the generated xml bean class after the
“parse()” call, and it says that the xml is invalid. I think this is why
its not working – it cannot parse the xml, so thus it cannot populate
the generated xml bean object.
Can a non document level generated XmlBean factory parse the
corresponding xml fragment and properly populate the generated XmlBean
object? It seems like it (also seems like a very useful feature).
I have been reading the XmlBeans documentation, and googling all day,
but I cannot get a clear answer about this (at for me).
Below is the relevant code snippets that exhibit this behavior.
My xsd is something like this:
<xsd:schema
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:cfgr="http://prosrm.com/configurator/xmlbeans";
targetNamespace="http://prosrm.com/configurator/xmlbeans";
elementFormDefault="qualified">
<xsd:element name="Application">
<xsd:complexType mixed="false">
<xsd:sequence>
<xsd:element name="Table" type="cfgr:Table"
minOccurs="1" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Table" mixed="false">
<!-- "Table" is a list of "Column"s and "Constraint"s -->
<xsd:sequence>
<xsd:element name="Column" type="cfgr:Column" minOccurs="1"
maxOccurs="unbounded"/>
</xsd:sequence>
<xsd:attribute name="name" form="unqualified" type="xsd:string"
use="required"/>
</xsd:complexType>
…
Using the generated XmlBeans Table class from the above xsd , the code
below tries to parse a “Table” xml fragment into a generated XmlBeans
“Table” object. It then tries to access the “name” attribute on this
object (this returns null). It then does the validate (which fails):
// parse Table xml fragment into a Table object. The
"toString()" works!!
String tableStr = "<xml-fragment
xmlns:cfgr=\"http://prosrm.com/configurator/xmlbeans\"; >" +
" <cfgr:Table name=\"MyTable1\" >" +
" <cfgr:Column name=\"MyCol\"
type=\"string\" length=\"20\" />" +
" <cfgr:Column name=\"MyCol2\"
type=\"string\" length=\"25\" />" +
" </cfgr:Table>" +
"</xml-fragment>";
// Create an XmlOptions instance and set the error listener.
XmlOptions validateOptions = new XmlOptions();
ArrayList errorList = new ArrayList();
validateOptions.setErrorListener(errorList);
Table tbl1 = Table.Factory.parse(sr);
System.out.println("Parsed from String. My Table 1 name
is:\n\n" + tbl1.xgetName()+"\n");
System.out.println("tbl1.validate() = " + tbl1.validate(validateOptions));
for (int i = 0; i < errorList.size(); i++)
{
XmlError error = (XmlError)errorList.get(i);
System.out.println("\n");
System.out.println("Message: " + error.getMessage() + "\n");
System.out.println("Location of invalid XML: " +
error.getCursorLocation().xmlText() + "\n");
}
When I run this code, I get the following output:
