Validating XML with PL/SQL parser
How can i validate a xml that is on a buffer with the grammar
stored in a BLOB column of o table? I'm using PL/SQL parser and
i can parse it correctly but i don't know how can i validate it
because my grammar is stored in DB.

You can't currently but this will be available in our next
release.

Validate xml with PL/SQL Parser
Hi,
i have an xml DTD into a VARCHAR2 variable and an xml document
into a CLOB, i'd like to know how to validate the xml with my
DTD using PL/SQL API for xml.
Sorry for my terrible english (i'm not english) :-)
Tank you.Here's an example:
set serveroutput on
DECLARE
p xmlparser.parser;
d xmldom.DOMDocument;
dtd xmldom.DOMDocumentType;
v varchar2(32700);
good clob;
bad clob;
xml_parse_error exception;
pragma exception_init(xml_parse_error,-20100);
BEGIN
bad := '<!DOCTYPE Department SYSTEM "test.dtd"><Deprtment/>';
good := '<!DOCTYPE Department
SYSTEM "test.dtd"><Department/>';
v := '<!ELEMENT Department EMPTY>';
p := xmlparser.newParser;
xmlparser.parseDTDBuffer(p,v,'Department');
xmlparser.setDoctype(p,xmlparser.getDoctype(p));
xmlparser.setValidationMode(p,TRUE);
xmlparser.parseClob(p,good);
xmlparser.parseClob(p,bad);
xmlparser.freeParser (p);
EXCEPTION
WHEN xml_parse_error THEN
DBMS_OUTPUT.PUT_LINE(sqlerrm);
xmlparser.freeParser (p);

Error validating xml with xsd schema on JSDK 1.4
Hi All,
Asked to me do it a Web Service client in Java and validate its xml answer with an xsd file using 1.4 plataform.
I googled and I saw many samples to 1.5 plataform, and few samples to 1.4, but anyway I tried to do what they asked to me.
I got connect with service, got the response and so I went to validate that xml with an xsd file.
But I got an error on that task. The error occurs in the following line

Generate Valid XML from pl/sql
Hi,
A new-bee here. I want to know how to generate a valid xml document. I have a schema which by the way includes two other schemas. This is the code I am using but I don't know how to make sure that I insert the child nodes in the right sequence. Any sample code that you guys can provide would be greatly appreciated.
FUNCTION GenerateOrderXML(
o_ErrorCode OUT NUMBER,
o_ErrorText OUT VARCHAR2,
i_AccountID IN document.documentid%TYPE,
i_OrderName IN VARCHAR2) RETURN XMLType
IS
v_Doc XMLDOM.DOMDocument;
v_MainNode XMLDOM.DOMNode;
v_RootElmt XMLDOM.DOMElement;
v_RootNode XMLDOM.DOMNode;
v_TmpCLOB CLOB := ' ';
CURSOR CURSOR_SERVOBJ
IS
SELECT XMLTAG, XMLVALUE FROM SERVICEOBJECT
WHERE SERVICEOBJECT.ID < 500
ORDER BY SEQUENCE;
-- Create xml root element
v_Doc := XMLDOM.newDOMDocument;
v_MainNode := XMLDOM.makeNode(v_Doc);
v_RootElmt := XMLDOM.createElement(v_Doc, 'OrderRequest');
v_RootNode := XMLDOM.appendChild(v_MainNode, XMLDOM.makeNode(v_RootElmt));
-- Add OrderName, OrderType
AddChild(v_Doc, v_RootNode, 'orderName', i_OrderName);
AddChild(v_Doc, v_RootNode, 'orderType', 'NA');
-- Add all attributes
FOR v_NameValue IN CURSOR_SERVOBJ
LOOP
AddChild(v_Doc, v_RootNode, v_NameValue.XMLTAG, v_NameValue.XMLVALUE);
END LOOP;
-- XMLDOM.writeToBuffer(v_Doc, v_Buffer);
XMLDOM.writeToClob(v_Doc, v_TmpCLOB);
o_ErrorCode := 0;
RETURN XMLType.createXML(v_TmpClob);
END;The r was a typo. The messge is correct.
Here is another problem I am having. I can't import a schema that includes another schema. When I try to register the third schema I get the following error. The first two register without any errors and when I run this
select schema_url from user_xml_schemas;
I see
http://www.bbc.com/XMLSchema/sfi.xsd
http://www.bbc.com/XMLSchema/ProductModel.xsd
So why is my third schema not importing? Can you point me to any good documentation/tutorials on XML DB.
Note: Thank you for your help so far.

Hi,
I have found a piece of code through google, to validate an xml file with an external dtd file. which is
function validateDocument()
xmlDocumentObject = new ActiveXObject("microsoft.XMLDOM")
xmlDocumentObject.onreadystatechange = changeHandler
xmlDocumentObject.load('C:\\My.xml')
function changeHandler()
and for that we need to a import i.e #import "C:\WINDOWS\system32\msxml4.dll"
here when i try to import "msxml4.dll" in Acrobat javascript (js) file, it is giving error, application exits.
How can i import dll in Acrobat javascript to get some functionality, or if not
What someother way to achieve this(To validate xml with dtd file).
This is totally making me crazy, please someone help me on this issue.
thanks in advance.thanks Leonard,
But my problem is i have an xml(i created that using acrobat javascript)and a dtd file, i want validate xml file with that dtd, using acrobat or some other way. How can i validate xml with dtd, please help me. -

Problem validating XML with XSD
Hi everyone. I have an xsd schema and I want to validate some XML doc with the schema using SAX parser.
The user make the xml and then upload it to the server.
I want to enable client side validation but, for security reasons, I want also to validate this document when it's uploaded to the server.
The schema called ContentSchema.xsd
<?xml version="1.0" encoding="ISO-8859-1" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="www.mysite.com/Content" xmlns="www.mysite.com/Content">
<xs:element name="content">
<xs:complexType>
A document produced by the client starts in this way:
<?xml version="1.0" encoding="UTF-8"?>
<p:content xmlns:p="www.mysite.com/Content" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="www.mysite.com/Content ContentSchema.xsd">
in this way users can validate the XML doc before uploading. If the XSD is in the same folder of the uploaded XML the validation is ok.
The problem is that, on the server, I've stored the xsd file in a folder and I want the SAX parser to use this xsd to validate the XML. Even I pass the complete URI of the file to the parser, it won't work:
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setValidating(true);
spf.setNamespaceAware(true);
spf.setFeature("http://apache.org/xml/features/validation/schema",true);
spf.setFeature("http://apache.org/xml/features/validation/schema-full-checking", true);
SAXParser sp=spf.newSAXParser();
sp.setProperty("http://apache.org/xml/properties/schema/external-schemaLocation", schemaURL );
I set the schemURL with setProperty method but it's like the parser is looking for the XSD in the URL declared in the XML doc and not in the URI I specify. Anyone can help me?
Thank you very muchYou will have to associate the schema with the namespace, like in your xsi:schemaLocation attribute.
Try something like this:
sp.setProperty("http://apache.org/xml/properties/schema/external-schemaLocation", "www.mysite.com/Content "+schemaURL); -
While executing the sample procedure for XML/PLSQL Parser it gives the error:
ERROR at line 1:

Wht should i do to rectify this error?

========================
Hello.
I have exactly the same problem and the above SQL does not return any rows.
I upgraded my 8.1.5 on NT to 8.1.6. On trying to install the PL/SQL XML parser, received errors with resolving classes. Suspecting problems with Java VM, I re-installed the JVM using initjvm.sql. On successfull completion, i re-tried installing the parser. Still have the same problems.
Is there anything else i could try?

IllegalArgumentException - error validating xml with schema
I'm trying to validate an XML document using the following:
JAXP 1.2
Xerces 1.4.4
JDK 1.4.1
The xml is valid and I can confirm it with XML Spy when I point it to the schema definition. But, I get an IllegalArgumentException when I try to do it in my class.
Here's the code...
public static final String JAXP_SCHEMA_LANGUAGE = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
public static final String W3C_XML_SCHEMA = "http://www.w3.org/2001/XMLSchema";
public static final String CIS_SCHEMA = "D:\\dev\\xml\\cis.xsd";
public static final String[] SCHEMAS = { W3C_XML_SCHEMA, CIS_SCHEMA };
private static DocumentBuilderFactory dbf;
private static DocumentBuilder db;
try {
dbf.setNamespaceAware(true);
dbf.setValidating(true);
dbf.setAttribute(JAXP_SCHEMA_LANGUAGE, SCHEMAS);
} (catch ...) {
I get the following error:
java.lang.IllegalArgumentException: http://java.sun.com/xml/jaxp/properties/schemaLanguage
Any ideas?When I tried this with Xerces SAX, I got---
org.xml.sax.SAXNotRecognizedException: http://java.sun.com/xml/jaxp/properties/schemaLanguage
Maybe Xerces has not implemented the schemaLanguage property.
I have been successfully using Xerces-dependent properties to do validation:
XMLReader parser = saxParser.getXMLReader();
parser.setFeature( "http://xml.org/sax/features/validation", true);
parser.setFeature( "http://xml.org/sax/features/namespaces", true);
parser.setFeature( "http://apache.org/xml/features/validation/schema", true);
parser.setFeature( "http://apache.org/xml/features/validation/schema-full-checking", true);
if (noNamespaceSchemaLocation!=null) {
parser.setProperty(
"http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
noNamespaceSchemaLocation);
if (schemaLocation!=null) {
parser.setProperty(
"http://apache.org/xml/properties/schema/external-schemaLocation",
schemaLocation);
Also, as DrClap pointed out, for the schema location I use URIs.
Please let me know if you got the jaxp schemaLocation property to work and how you did it. -
