Validate XML file using nested XSD's

Hi,
I am currently trying to create a method that can validate a XML document based on a long series of nested XSD's.
I am however not sure of how to implement this validation with the nested XSD's.
Currently I have created the following function:
     public void validate(InputStream xmlDocument) {
          try {
               SAXParserFactory spf = SAXParserFactory.newInstance();
               spf.setNamespaceAware(true);
               spf.setValidating(true);
               SAXParser sp = spf.newSAXParser();
               InputStream schema1 = this.getClass().getResourceAsStream("schema.xsd");
               InputStream schema2 = this.getClass().getResourceAsStream("schema1.xsd");
               Object[] schemas = {schema1,schema2};
               final String JAXP_SCHEMA_LANGUAGE = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
               final String W3C_XML_SCHEMA = "http://www.w3.org/2001/XMLSchema";
               final String JAXP_SCHEMA_SOURCE = "http://java.sun.com/xml/jaxp/properties/schemaSource";
               sp.setProperty(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
               sp.setProperty(JAXP_SCHEMA_SOURCE, schemas);
               sp.parse(xmlDocument, new ParseErrorHandler());
          } catch (SAXException e) {
               System.out.println(e.toString());
          } catch (ParserConfigurationException e) {
               System.out.println(e.toString());
          } catch (IOException e) {
               System.out.println(e.toString());
The schemas that I reference are imported into the namespace of the class that contains the above method. schema.xsd contains a reference to schema1.xsd.
The exception that I get is:
com.sap.engine.lib.xml.parser.NestedSAXParserException: Generic Exception: -> com.sap.engine.lib.xml.util.NestedException: [location : null] ERROR : schema1.xsd (The system cannot find the file specified)
This I dont understand since the schema1.xsd is located right along with schema.xsd which is found without trouble.
Hope someone can clearify this issue for me, since I'm somewhat lost.

Daniel

How to generate XML file based on XSD in SSIS

please provide step by step process to create xml based on XSD in SSIS

Hi hemasankar,
In SQL Server Integrated Services, we can generate XML Schema (XSD) file based on a XML file with XML Source Editor. If we want to generate XML file based on a XSD file, we can use Generate Sample XML feature in Visual Studio. For more details, please refer
to the following steps:
Click on "XML Schema Explorer" or 'Use the XML Schema Explorer...' to open XML Schema Explorer in Visual Studio.
If your Schema file is valid and you are having elements, right-click on element and click on "Generate Sample XML", this functionality generates XML file in temp folder and open ups in the XML Editor.
The following two document about how to generate XML file based on a XSD file are for your reference:
http://msdn.microsoft.com/en-us/library/dd489258.aspx
http://www.codeproject.com/Articles/400016/Generate-Sample-XML-from-XSD
If there are any other questions, please feel free to ask.

How to update XML file using XSLT

Hi there,
I have a "small" issue with exporting data to an XML file using XSLT.
A two steps process is needed to import data from a non-hierarchical XML file into ABAP, change the data, and then update the XML file with new values. The problem is not trivial, since the format of the XML file is a complex one: there are many interdependent elements on the same level, pointing to each other by using id and ref attributes. Based on these values the data can be read and written into an internal table. I use XSLT and XPath for that. So the inbound process is done and seems to work correctly. I have to mention that the file contains much more data than I need. I am working only with a small part of it.
Now the changed data must be exported back into the XML file, meaning that the content of certain elements must be updated. How can this be done with XSLT? I can pass only the internal table to the transformation, so how do I access the XML file in order to update it? I have tried to use the <B>xsl:document()</B> function to access the content of the file store locally on my PC, but it fails each time by throwing and URI exception. I have tried the absolute path without any addition and the path with the file:/// addition. Same result. Please advise.
Many thanks,
Ferenc
P.S. Please provide me with links only if they are relevant for this very matter. I will not give points for irrelevant postings...

Now the changed data must be exported back into the XML file, meaning that the content of certain elements must be updated. How can this be done with XSLT?
XSLT approach: check these online tutorial
http://www.xml.com/pub/a/2000/08/02/xslt/index.html
http://www.xml.com/pub/a/2000/06/07/transforming/index.html
ABAP approach:
for example you have the xml (original) in a string called say xml_out .
data: l_xml type ref to cl_xml_document ,
        node type ref to if_ixml_node .
create object l_xml.
call method l_xml->parse_string
exporting
    stream = xml_out.
node = l_xml->find_node(
    name   = 'IDENTITY'
   ROOT   = ROOT
l_xml->set_attribute(
    name    = 'Name'
    value   = 'Charles'
    node    = node
(the above example reads the element IDENTITY and sets attribute name/value to the same)
like wise you can add new elements starting from IDENTITY using various methods available in class CL_XML_DOCUMENT
so how do I access the XML file in order to update it?
you have already read this XML into a ABAP variable right?
Sorry couldnt understand your whole process, why do you need to read local XML file?

How to validate xml file ?

I try to validate my xml import file but I can't find proper validation and error message.
the source where it originates is a system where also texts can be entered manually which are part of the xml file.
I discoverd myself that & and ! are characters which are not allowed. but I'm looking for a way to check this before I process the xml file.
I have this coding and I found smum_xml_parse but still the error is not clear about what is wrong ?
try.
    CALL TRANSFORMATION ('ID')
    SOURCE XML it_xml_import
    RESULT order_header_in = st_sdhd1 order_conditions_in = ta_cond order_partners = ta_parnr order_text = ta_sdtext order_items_in = ta_sditm
CATCH cx_xslt_exception INTO xslt_error.
xslt_message = xslt_error->get_text( ).
    ASSIGN COMPONENT 'ERROR' OF STRUCTURE <l_line> TO <l_field>.
    <l_field> = xslt_message.
data: gt_temp type STANDARD TABLE OF SMUM_XMLTB.
itx_xml_import = it_xml_import.
CALL FUNCTION 'SMUM_XML_PARSE'
EXPORTING
    xml_input       = itx_xml_import
tables
    xml_table       = gt_temp
    return          = ta_ret2
ENDTRY.
the xslt_message is also very unclear of what is exactly wrong with the file.
are there any function which can give me more detailed information about the xml file and what is wrong with it ?

How to get XML file using servlets that XI sent to my J2EE appl?

Hi All!
I have a scenario like XI sends xml file to j2ee application. In my J2EE application my servlet receives this xml. Will the xml file be in my HTTPServletRequest object? if so how to get that file from Request object.
Please help me its urgent, Any code help is highly appreciated.
My xml file will be like this:
<ns0:Http_Message_Type_Demo
xmlns:ns0="http://abcdemo.com">
<Name>ABC</Name>
<RollNo>123</RollNo>
<Address>a-4</Address>
</ns0:Http_Message_Type_Demo>
somebody should help me!please
Thanks

Hi,
You can use HTTPServletRequest object to get the XML payload.
BufferedReader reader = request.getReader(); //gets XML payload
String line = reader.readLine(); // to read the XML payload line by line
(request is the HTTPServletRequest object)

Uma

How to validate XML using java_xml_pack-summer-02?

In jaxp1.1, we validate the xml file in this way:
c:\java -jar Validator.jar myBookStore.xml
However, in java_xml_pack-summer-02, which is latest version of jaxp, the Validator.jar is not available. So, how to validate xml file?
Pls help.

develop your own validator... here is a quick and dirty one, which spits exceptions when error are met:
import java.io.*;
import javax.xml.parsers.*;
import org.xml.sax.*;
import org.xml.sax.helpers.DefaultHandler;
public class Validator
public static void main(String[] args) throws Exception {
    SAXParserFactory spf = SAXParserFactory.newInstance();
    spf.setValidating(true);
    spf.setNamespaceAware(true);
    SAXParser sp = spf.newSAXParser();
    sp.parse(new File(args[0]), new DefaultHandler());
}

How to validate XML against XSD and parse/save in one step using SAXParser?

How to validate XML against XSD and parse/save in one step using SAXParser?
I currently have an XML file and XSD. The XML file specifies the location of the XSD. In Java code I create a SAXParser with parameters indicating that it needs to validate the XML. However, SAXParser.parse does not validate the XML, but it does call my handler functions which save the elements/attributes in memory as it is read. On the other hand, XMLReader.parse does validate the XML against the XSD, but does not save the document in memory.
My code can call XMLReader.parse to validate the XML followed by SAXParser.parse to save the XML document in memory. But this sound inefficient. Besides, while a valid document is being parsed by XMLReader, it can be changed to be invalid and saved, and XMLReader.parse would be looking at the original file and would think that the file is OK, and then SAXParser.parse would parse the document without errors.

Have you looked at the XML DB FAQ thread (second post) in this forum? It has some examples for validating XML against schemas.
