Comparing two XML Schemas

Hi All,
I want to compare two versions of the same XML Schema. I am working with Oracle 10g XML DB. I think we have something in 11g but I am constrainted to 10g.
Requirement:
1. I start afresh and register the XML Schema and also insert XML documents compliant to that schema in my XMLTYPE table.
2. Now after some time, I need to add a new element. So, I modify the XML Schema and write the XSLT for its addition to XML documents and do a CopyEvolve(). Let us assume, I have a script for this.
3. Now if accidentally, I rerun the script, I may run into errors as the element is already there.
So, I thought I should find the differences between the new version of the schema and the old version and if there are differences apply the XSLT and also evolve the schema. How do we do this?
Also, Can we generate the XSLT automatically based on the two versions of XML Schema?
Thanks
Ramesh

XML Schemas are just XML documents.
Compare the XML Schemas using the XDK's XMLDiff class and generate the XSLT from the differences.

How to compare two xml schemas

Hello guys,
How to compare two xml schemas? is there any tool for that?
Thanksinadvance

XML Files may be compared with the oracle.xml.differ.XMLDiff class.
A file consisting of the differences in the xml files gets generated. An XSLT to convert one file to the other also gets generated.

Compare two XML files: Analysis and Design

Hi, Java/XML/JDOM experts,
I realised that an open source of Java utility to compare two XML is still missing. So I would like to write one for my JDOM excises.
I plan to do it in three steps:
1.Define the problem domain.
2.Design the classes to be developed.
3.Coding
Below is the problem domain. Would you review it and tell me if it is fine?
Best regards,

Compare two XML files
Schema assumption:
The xml files used for the comparison must have the same schema.
Definition:
1. Two elements of simple type are said equal if their name and value are identical.
2. Two elements of complex type are said comparable if their name, attributes are identical.
3. Two elements of complex type are said equal if they are comparable and their children elements are identical.

Hi,
Thanks for reviewing my idea.
The xml files used for the comparison must have the
same schema.Including not having a schema at all? And if they do
have a schema, must they be valid according to the
schema?I will only support schema based xml files. To include a schema is a good practice. So I will valid them agaisnt schema (is this possible with JDOM? I am testing ...)

2. Two elements of complex type are said comparableif
their name, attributes are identical.
3. Two elements of complex type are said equal ifthey
are comparable and their children elements are
identical.Do you plan to require child elements to appear in the
same order for the two documents to be equal? (Note
that XML specifically says that the order of
attributes is not significant.)No. The order is not significant as I use the attributes as the keys to find comparable element counterpart.
Here is the sample code already tested. Any comments are welcome!
The next step is to define the "delta xml schema" that will guide me to store the comparasion results. Do you have any suggestions?
Regards.

public static boolean comparable(Element element1, Element element2)
     boolean returnValue=false;
     if (element1.getName()!=element2.getName()) {
          return returnValue;
} else {
          returnValue=true;
                    System.out.println ("place 2");
     List attributeList=element1.getAttributes();
     Iterator attributeIterator=attributeList.iterator();
     Attribute workingAttribute=null;
     while (attributeIterator.hasNext()) {
                         if (!workingAttribute.getValue().equals(
                         element2.getAttribute(workingAttribute.getName(), workingAttribute.getNamespace()).getValue()))
                              returnValue=false;
                              break;

Comparing two XML using DOM

Hi All,
I am comparing two XML nodes having same nodes using DOM parser.
<?xml version="1.0"?>
<compare value="xml1"/>
< test name="java">
      <compare value="xml">
          <node>012</node>
</compare>
</test>
< test name="java1">
      <compare value="xml2">
          <node>013</node>
      </compare>
      <compare value="xml3">
          <node>014</node>
     </compare>
</test>I need to take <compare> and <node> present inside <test> tag.
I am not getting the results properly if i am using the following code
NodeList bList1 = doc.getElementsByTagName("compare");
                    for (int temp1 = 0; temp1 < bList.getLength(); temp1++) {
                      Node nNode = bList.item(temp1);
                      NamedNodeMap attributes = (NamedNodeMap)nNode.getAttributes();
                                      for (int g = 0; g < attributes.getLength(); g++) {
                                          Attr attribute = (Attr)attributes.item(g);
                                          System.out.println(" Attribute: " + attribute.getName() +
                                          " with value " +attribute.getValue());
                                       if (nNode.getNodeType() == Node.ELEMENT_NODE) {
                    Element eElement = (Element) nNode;
                                      NodeList nlList= eElement.getElementsByTagName("node").item(0).getChildNodes();
                Node nValue = (Node) nlList.item(0);
                String node = nValue.getNodeValue();
}is there any possibility to get the <compare> and <node> tag present inside <test> tag...

I need to get the attribute value of <compare> and body value for
<node> tag and need to compare the values in both XML.

How can i compare two XML files storeds in a LONG column

Hi,
I need to compare two xml files. My xmls are stored in two table like this:
Table 1
ID_COL number(5);
XML1 LONG()
Table 2
ID_COL number(5);
XML2 LONG()
I need compare the values of the tags of this xmls files e to list de differences.
Tks,
Fernando.

yes odie you are right...i think that my xml is wrong...

hi,
i am not aware of these things(merge file).
can u tell me,what is the ultimate result of this merging.
and can u tell the stepts to acheive this..
Thanks..a) write files down to temporary directory by using text_io
b) call an external program you installed on the client like winmerge, windiff or about 100000 other programs out ther that can show you the differences of two files
this programs you pass the two files you wrote to disk at step a

Comparing two xml files in pl/sql

What is the best way to compare two 'complex' xml structures and return the difference using a plsql procedure/function. Example:
FUNCTION f_equals(XMLTYPE actualxml, XMLTYPE expectedxml) RETURN VARCHAR2
this should return 'EQUAL' if they are equal and the actual node with value if different..
Can somebody throw some ideas please?

The solution would depend on what you are trying to achieve, is it node to node comparison? overall file comparison? If there is any difference in either of the aforementioned approach, do what with the result?

How to compare two oracle database schemas

hi all,
i want to compare and find out differences between two oracle databases. The comparison should be made on between table definition,table data,primary and foreign keys, packages and functions.
Is there any management console or tool embedded in the oracle enterprise manger?
it is really appreciate if anyone can point me towards wright direction asap.

Hi ,
This script would help u a lot in comparing 2 schemas and generate a report on them.
Script:
This script will compare two Oracle schemas and generate a report of
discrepencies and this script has been used against Oracle 7.3.4, 8.0.5,
REM and 8.1.7 databases, but it should also work with other versions.
REM
REM Please note that the following schema object types and attributes are
REM not compared by this script at this time:
REM
REM cluster definitions
REM comments on tables and columns
REM nesting, partition, IOT, and temporary attributes of tables
REM snapshots/materialized views, logs, and refresh groups
REM foreign function libraries
REM object types
REM operators
REM indextypes
REM dimensions
REM auditing information
REM new schema attributes added for Oracle 9i

Tool for comparing two schemas....

Do we have any tool avalilable in oracle that compares two different schemas and find out the differences between two so that we can validate a schema against a standard one?

Hi.
Toad have option that is called just like that , compare schemas, and when used to compare two schemas it outputs diferences between them.
I dont know about any other tool.

Compare 2 xml file in background

Hello,
I want to compare two XML files in background containing data like following:
<ReportingDocument>
        <CompanyCode>1000</CompanyCode>
        <TransactionDate>2000-01-05</TransactionDate>
        <InvoiceProperties>
            <SupplierInvoiceNumber>000000162000VSTX</SupplierInvoiceNumber>
            <InvoiceNumber>0100000000</InvoiceNumber>
         </InvoiceProperties>
</ReportingDocument>
As result, i have to receive automatically Email in my outlook inbox like something:
Test is ok.
OR
Test is not ok, differences in invoiceNumber,.....
can some one help me ?
Regards,
Ouail.

Ouail,
1) Read XML file using open dataset (because it's in background)
2) Download files to program memory
3) Get the invoice number (example, next 10 chars after <InvoiceNumber>... or between <InvoiceNumber> and </InvoiceNumber> from these 2 files
4) Check if invoice number isn't char (in case that when initial the next characters are the closing tag).
5) Compare both invoice values from xml files
6) Build the text email with the compare detail. "...test is not ok... / .... Teste is ok...."

Maximum length for an XML schema

Hi everybody,
Is there a limit on the maximum length for an XML schema? I am trying to register an XML schema using dbms_xmlschema.registerSchema(). The schema registration process seems to go fine when the length of the schema is short. But the registration process always hangs when I increase the XML schema with additional types/elements. Is there a limit on the maximum length of the XML schema with regards to registering it to Oracle?
Thanks!

Hi Erhan,
Let's say I have a really big XML schema in file "schemaA.xsd", like so:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:sampleA="http://abc.com/schemaA" targetNamespace="http://abc.com/schemaA">
<xsd:element name="Employee">
<xsd:sequence>
<xsd:element name="Address" type="sampleA:AddressType"/>
<xsd:element name="Contact" type="sampleA:ContactInfoType"/>
</xsd:element>
<xsd:complexType name="AddressType">......</xsd:complexType>
<xsd:complexType name="ContactInfoType">....</xsd:complexType>
</xsd:schema>
I can separate this schema into multiple smaller schemas (<32KB) by using the proper imports:
In file "sampleA.xsd":
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:sampleB="http://abc.com/schemaB"
xmlns:sampleA="http://abc.com/schemaA" targetNamespace="http://abc.com/schemaA">
<xsd:import namespace="http://abc.com/schemaB" schemaLocation="schemaB.xsd"/>
<xsd:element name="Employee">
<xsd:sequence>
<xsd:element name="Address" type="sampleB:AddressType"/>
<xsd:element name="Contact" type="sampleB:ContactInfoType"/>
</xsd:element>
</xsd:schema>
And in file "sampleB.xsd", I might have something like this:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:sampleB="http://abc.com/schemaB" targetNamespace="http://abc.com/schemaB">
<xsd:complexType name="AddressType">......</xsd:complexType>
<xsd:complexType name="ContactInfoType">....</xsd:complexType>
</xsd:schema>
So, you see how I have separated that one really big XML schema in file "schemaA.xsd" into two XML schema files: "schemaA.xsd" and "schemaB.xsd". Also, I have added <import> tags in schemaA.xsd to refer to elements, complext types, etc. defined in schemaB.xsd. So long as these schema files are < 32KB, I can register them (using dbms_xmlschema.registerSchema()) without any problems into Oracle.
Let me know if what I said above is not too clear. Hope you find your solution soon!
Thanks!

Comparision of two xml files

Hi all,
Could anybody tell me how to compare two xml files and find the details that differ?
If possible, can you get me the code?

You can simply compare the entire contents of the strings if you like, although simple whitespace differences (spaces, tabs, carriage returns, etc.) would result in an evaluation that the two are different (probably not what you want). You can parse them in DOM or SAX, and the minute an element fails, return false. Look up a tutorial on either DOM or SAX for ideas. Or you could iterate through the string and simply discard whitespace on your own.
It could potentially be more complicated then that. Does the ordering of elements matter? Meaning if I have elements a, b, c in document one but b, c, a in the other one (but a, b, c are identical otherwise) does that mean a different document? You really do not have enough requirements to go on. The above will likely work for you, and no, I will not write your code for you.

How to compare the contents of two XML documents

Hi all,
I was trying to compare the contents of two xml documents, they are both validate for the same XML Schema. i was using the xmlunit to do this. but some how it doesn't work like what i have expected. for example:
1.xml : <test><item>2</item><item>1</item></test>
2.xml: <test><item>3</item><item>2</item><item>1</item></test>
the result from XMLUnit is this two xmls are different, but it compares <item>2</item> with <item>3</item>, which i cannot find out where the real diiffs are.
does anybody know how i can do this correct?
best regards,
tina

I faced a similar problem in one of my projects and hence wrote my own comparator. Most comparators like ExamXML etc show XML as different if the nodes under a parent node occur in different seqeunce or a set of repeated nodes occur in different sequence. The comparator that I wrote gives you the flexibility to configure how to identify a node from a set of repeated nodes and is able to compare them successfully if they occur in any order. You can view the sample output at http://geocities.com/dheerendra_itbhu/TipsFromDheeru.html
and contact me in case you need the source code.

You can do it with gridcontrol. Look for dictionary comparisons and dictionary baselines.
If you don't have gridcontrol, you can also use SQLDeveloper (free download on otn).
There are two ways to do it with SQLDeveloper.
1) Use Tools->Database Diff. However, you need a change management license to use this functionality. I've never used this.
The free way is to...
2) Use Tools->Database Export. Run it once for each schema and make sure the "Show Schema" option is NOT checked before exporting the schema. Also make sure you don't export data. You can choose which types of objects to export as well.
Once you have the two export files for the two schemas then simply run a diff tool on your platform. Use the diff command line for linux or winDiff or something similar in windows.
