Java program for xml validation

When parsed, each element in the data set will be validated against the appropriate schema, as long as those schemas have been declared. Again, the schemas can be declared either as part of the XML data set or in the program. It is also possible to mix the declarations.

In general, though, it is a good idea to keep all the declarations together in one place. To declare the schemas to use for the preceding example in the data set, the XML code would look something like the following.

The noNamespaceSchemaLocation declaration is something you have seen before, as are the last two entries, which define the namespace prefixes tax and hiring. What is new is the entry in the middle, which defines the locations of the schemas to use for each namespace referenced in the document. The xsi:schemaLocation declaration consists of entry pairs, where the first entry in each pair is a fully qualified URI that specifies the namespace, and the second entry contains a full path or a relative path to the schema definition.

In general, fully qualified paths are recommended. In that way, only one copy of the schema will tend to exist. Note that you cannot use the namespace prefixes when defining the schema locations.

The xsi:schemaLocation declaration understands only namespace names and not prefixes. To declare the equivalent schemas in the application, the code would look something like the following.

Here, the array of strings that points to the schema definitions. Note the differences from when you were declaring the schemas to use as part of the XML data set. Source file: XMLHelper. Source file: XmlHelper. Source file: XMLImporter. Source file: Parser. Source file: XSDChecker. Source file: ValidationComponent. Source file: FeatureValidationUtil.

Source file: SchemaTest. This validation works fine field by field in top down approach like field1 comes first and field2 next,if both fields are invalid as per XSD then error will be thrown for only field1. I really appreciate if u can share how to validate whole XML against XSD in one shot so that all the errors will be thrown in a single response.

I am having a situation where I will get some data from a Stream at run time and I need to convert it into XML by performing some general validations. I am not having any xsd ot xslt. How to create the xsd in the first place. Any tools or Eclipse menu option available to create the xsd from xml? Hi plese provide the code for the same above mentioned but not single its multiple xsd. So please give the code.

And one xsd is included in other xsd and so on. So I want to validate this xml file against the multiple schemas. With above mentioned link still i am not able to get all exception, It is throwing only single exception, Can you please let me know.. It is very urgent.. In my xml i have Enums, and if i delete all still it throws only single exception, not for all enums, can any body know the solutions.
