In front of me there is a problem - a complete schema parse (with include, import, redefine). The problem, is not even parsing scheme, it's to resolve types from this schema.
To explain the problem, here is an example:
schema.xsd:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:myprefix="http://myhost.ru/service/" xmlns:anprefix="http://anotherhost.ru/pub-service/" targetNamespace="http://myhost.ru/service/">
<xs:import namespace="http://anotherhost.ru/pub-service/" schemaLocation="anotherhost_schema.xsd"/>
<xs:complexType>
<xs:sequence>
<xs:element name="ServiceCode" type="anprefix:ServiceCodeType">
<xs:annotation>
<xs:documentation>Service code</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="MessageClass" type="myprefix:MessageClassType"/>
</xs:sequence>
</xs:complexType>
<xs:simpleType name="MessageClassType">
<xs:restriction base="xs:string">
<xs:enumeration value="REQUEST">
<xs:annotation>
<xs:documentation>Request from client
</xs:documentation>
</xs:annotation>
</xs:enumeration>
<xs:enumeration value="RESPONSE">
<xs:annotation>
<xs:documentation>Response to client</xs:documentation>
</xs:annotation>
</xs:enumeration>
</xs:restriction>
</xs:simpleType>
</xs:schema>
anotherhost_schema.xsd:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:anprefix="http://anotherhost.ru/pub-service/" targetNamespace="http://anotherhost.ru/pub-service/">
<xs:simpleType name="ServiceCodeType">
<restriction base="xs:string">
</restriction>
</xs:simpleType>
</xs:schema>
Example is not very difficult, the real problem is much bigger. My problem is to parse schema and create it's internal representation (that form generator and request handler will use), for example, as follows:
{
"ServiceCode": {"string", String.class, "Service code"},
"MessageClass": {"string", {"REQUEST":"Request from client","RESPONSE":"Response to client"}, ""}
}
Inner representation can be various, but simple for use in Java. Is there such a library? I know, that there is a library, called JAXB, created specially for XML-parsing, but I don't understand how to bind it to my problem.

In my application, we use XSD validation to check whether the given text input is a number greater or equal to 0. This works fine, but when we enter numbers like 000 or 001 it validates it too. So when we write to a file it writes the 000 and 001 but we want to not validate them. We want them as 0 or 1, not 000 or 001.
How can we enable it and trim the 00 at the beginning? Is there an XSD type or restriction for it?
How can we solve this issue?
I am not sure if you only want to validate the content given to write or read from the files or also alter it. the xml schema cannot alter the data. Assuming the to be validated content is of the type string. You can use a regex pattern to check if the content is correct. the below example gives checks if the last character in the string is 0 or 1 and all the characters prior to it must be 0.
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="root">
<xs:complexType>
<xs:sequence>
<xs:element name="input">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:pattern value="(0*[0-1])?[0-1]"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

if you only want to approve the xml structure that has a single digit in the range of 0 to 9 you can use the below example.
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="root">
<xs:complexType>
<xs:sequence>
<xs:element name="input">
<xs:simpleType>
<xs:restriction base="xs:int">
<xs:pattern value="[0-9]"/>

I Cannot generate wsdl JAVA with wsimport for GetHotelMediaRQ. Could you please tell me how to resolve the problem?

The error is correct, this was defined 2 times. You need to download the WSDL and all the associated schemas.
The GetHotelMediaRS_v2.0.0.xsd looks like below xsd:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:stlp="http://services.sabre.com/STL_Payload/v02_02" xmlns="http://services.sabre.com/hotel/media/v2" targetNamespace="http://services.sabre.com/hotel/media/v2" elementFormDefault="qualified" attributeFormDefault="unqualified">

You should simply remove the complexType definition HotelMediaInfos, and you would end up with something like the bellow xsd:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:stlp="http://services.sabre.com/STL_Payload/v02_02" xmlns="http://services.sabre.com/hotel/media/v2" targetNamespace="http://services.sabre.com/hotel/media/v2" elementFormDefault="qualified" attributeFormDefault="unqualified">

</xs:documentation>
</xs:annotation>
</xs:element>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
</xs:element>
</xs:schema>
You can even replace the content above in the GetHotelMediaRS_v2.0.0.xsd, and you should be able to compile.
Personal recommendation, in the future, try to do these things yourself. It will help you learn and avoid depending on Sabre or the community.
I want to validate AGE filed in my schema but i have given some restriction on it but when i give the string value in AGE filed which is not throwing the error like "Invalid data for AGE". May i know how to solve this issue? Please find my sample code below.

[ERROR] src-resolve.4.1: Error resolving component 'cacheCode'. It was detected that 'cacheCode' has no namespace, but components with no target namespace are not referenceable from schema document 'file:/F:/Sprint6/cache/src/main/resources/CacheRefreshEvent.xsd'. If 'cacheCode' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'cacheCode' has no namespace, then an 'import' without a "namespace" attribute should be added to 'file:/F:/Sprint6/cache/src/main/resources/CacheRefreshEvent.xsd'.

Please help.
Remove this extra namespace attribute targetNamespace="http://www.hcentive.com/mea/trr"
OR add this xmlns="http://www.hcentive.com/mea/trr"
Both solutions will work :)
For you reference targetnamespace-and-xmlns
I've got something like the following XML file.

<property

<item>mhma03h</item>
</property>

First requirement is that this XML cannot change no matter what. Please don't suggest doing that below.
I need to write a schema that validates this. And Java code that does the validation.
I am completely stuck and I have no idea really what is going on.
What's a schema like this look like? I've gotten one but it's so bad I'm not going to bother posting. :P I don't want to have to append a namespace to the XML elements. They're set in stone.^_^
How do I just make it so all of these elements are just "found" by the parser? Can I just tell it ignore all this namespace nonsense. With this application of validating against a schema, namespace conflicts are simply impossible.
I've tried putting
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="books" elementFormDefault="unqualified">
for my namespace info and

Code to load and validate yes. Before you ask, the files are able to be loaded. I've checked like 20 times. :P
SAXParserFactory factory = SAXParserFactory.newInstance();
SchemaFactory schemaFactory =
SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");
factory.setSchema(schemaFactory.newSchema(
new Source[] {new StreamSource("small.xsd")}));
javax.xml.parsers.SAXParser parser = factory.newSAXParser();
org.xml.sax.XMLReader reader = parser.getXMLReader();
reader.setFeature("http://xml.org/sax/features/validation", true);
reader.setFeature("http://apache.org/xml/features/validation/schema", true);
reader.parse(new InputSource("small.xml"));

This may not correctly capture the requirements for each element and attribute (check that the min/max occurs, required/optional proprerties, etc... are set correctly) but it should get you started on working with an XML schema that will validate correctly. The schema does not define a target namespace so you won't have to worry about modifying the existing XML to add in namespace prefixes to your existing elements.
You need to find a way to tell the XML processor to use your namespace as the default when it is processing a document without an explicit namespace. Most processors have a way to do this, IIRC there is a method named setNoNamespaceSchema or something similar. You would write an XML schema with a namespace and tell the processor (validator, whatever) to use your namespace for documents that do not have an explicit namespace.
