XML Diff API

Hi!
I would urgently need an API providing functionality for comparing two xml files and creating a delta (e.g. which elements were deleted in the first file).
I was searching the web for hours and could just find applications, but no apis for java.
Hope that anyone could help me.
Thx, Christian

Where do I get it from? I think it's only included in the commercial license of Oracle 10g.

Schema-aware XML Diff utility

Is there a XML Diff utility/API that is schema aware? i.e. can determine that <foo bar="true"/> is the same as <foo/> if the schema says that the default value for the optional bar attribute is "true".
As far as I can see, oracle.xml.XMLDiff has no such feature.
Vijay

Most XML diff APIs are not schema aware. XML document differences implies differences in XML elements and attributes, not a validation of the XML documents with a schema.

How to trigger xml publisher API (ex:Delivering Documents via e-Mail)?

Dear All:
How to use xml publisher API ?
In user's guide always talk API's code.(ex:Delivering Documents via e-Mail
// create delivery manager instance
DeliveryManager dm = new DeliveryManager();
// create a delivery request
DeliveryRequest req =
dm.createRequest(DeliveryManager.TYPE_SMTP_EMAIL);
// set email subject
req.addProperty(DeliveryPropertyDefinitions.SMTP_SUBJECT, "Invoice");
// set SMTP server host
req.addProperty(
DeliveryPropertyDefinitions.SMTP_HOST, "mysmtphost");
// set the sender email address
req.addProperty(DeliveryPropertyDefinitions.SMTP_FROM,
"[email protected]");
// set the destination email address
req.addProperty(
DeliveryPropertyDefinitions.SMTP_TO_RECIPIENTS,
"[email protected], [email protected]" );
// set the content type of the email body
req.addProperty(DeliveryPropertyDefinitions.SMTP_CONTENT_TYPE,
"text/html");
// set the document file name appeared in the email
req.addProperty(DeliveryPropertyDefinitions.SMTP_CONTENT_FILENAME,
"body.html");
// set the document to deliver
req.setDocument("/document/invoice.html");
// submit the request
req.submit();
// close the request
req.close(); )
Not say how to use this code to account effect !!
Having anybody to use API before?
Please tell me how to use that,thanks!!

This is the class for a JCP I created to perform the following:
1) Launch an existing Concurrent Program that produces PDF output
2) Grab the PDF and apply a watermark based on user input or conditions
3) associate the modified PDF to CP output for PASTA printing
It isn't elegant but it is fairly simple. I added the email capability and tested it but am not implementing it at the present time.
there is a fair amount of information out there that explains how to create a JCP councurrent program but very little that demonstrates the class needed.
I hope this helps

XML diff and merge - free lib?

I'm using my own XML communication protocol and got a problem. I transfer a configuration with this protocol, and the config can grow very large. So I want to create a diff of old/new configuration an transfer only this diff. On the receiver side the last received config should be patched with the diff.
I'm using JDOM.
Is there a free lib for XML diff and merge/patch available? I already googled for it but found only a commercial lib.
Thanks in advance

I like ExamDiff for Windows. It was free last time I downloaded it, but I haven't looked in a while.
I don't know of any good merge tools, streamy. I'll have to crib what comes back from others.

Use XML-Diff Elsewhere

I have been looking for XML Diff for quite some time.
I was pleased to see the feature in a free application and it encouraged me to use JDeveloper
http://geoffadf.blogspot.com/2010/02/xml-merge-showing-automatically.html
What are the licence considerations for using this code (xml-compare.jar) elsewhere?
E.g. if I wanted to create a Swing Application to just do XML Diff or create a plugin for other IDEs?

You can't pick up code libraries from the core of JDeveloper and use it in your own application. The code belongs to Oracle.

Can we use javax.xml.parser API's from j2sdk kit?

Hi All,

Hi,
I am trying to read an xml file on Solaris.
Can we not use doc.getElementById(String elementID) after deriving doc obejct ?
Here is the code I am trying to use:
try
factory = DocumentBuilderFactory.newInstance();
factory.setValidating(false);
File file = new File("/command/parse_doc.xml");
doc = factory.newDocumentBuilder().parse(file); //upto here it works
Element element = doc.getElementById("Topics");
String name = element.getTagName(); //returns nothing but throws exception "null"
}catch(Exception exe){
out.println("Exception:" + exe.getMessage());}
here I get no such element, and the try catch block exception also null.
Is there something I am missing?
DO I have to call doc.getDocumentElement() before I call get ElementBy ID() and if so why?
Thanks.

XML DOM API vs. XPATH

Hi,
We are using Oracle v9.2.0.4. Can any one share there knowledge regarding the XML DOM API and XPATH? What are pros and cons using either approaches? In terms of performance, what approach much better? Also, which approach can maintain the CDATA?
Here is a sample of an XML. Please show some sample on how to get the values for SHOP element using both XML DOM API vs. XPATH.

XML diff in XML DB

Hey All,
Is there a mechanism for getting a diff of XMLTypes/documents in XML DB? Or is the best bet to make/load in my own implementation? Obviously, I don't want to reinvent the wheel if I don't have to.
Thanks

Nothing in the current release :(...

Urgent - Need an answer - XML Java API

This is the 3rd time I've posted this question in last week - Oracle Support: How can I get an answer to this?
This question is about how to free up the memory of XMLDocuments, Parsers, etc using the Java APIs - not the PLSQL wrappers.
I'm writing an app using the DocumentSplitter class (from Steve M.'s book) that allows for the SAX parsing of large XML documents. But this question is really about the Oracle Java XML API.
Is there a way to free the memory of each of the "temporary" XMLDocuments that get created? I know there's a XMLNodeCover.freeDocument(int id)
method in the xmlplsql.jar- where do you get the id from? I'm trying XMLNodeCover.getDocumentId(curDoc) - but that doesn't seem to work.
And can I use that same method for each Node and Element that gets created also?
Also, would like to free the memory for the XSL processor, SAXParser, and XSLStylesheet - but this is even less obvious (although not as critical).
I'm actually getting out-of-memory errors even sooner when using the SAX parser then when using the DOM parser, and I think its due to this issue.
I know that there are PL/SQL wrappers for all these, but I'm trying to use the DocumentSplitter and associated custom classes
in only Java stored procs, and then writing a single XSLT.transform wrapper. This way its largely invisible to the PLSQL layer.
Thanks

Hi - thanks for your response.
Actually, yes, I did change the split method to return a CLOB. The big picture is I'm trying to use the DocumentSplitter
class to assist in the transformation of large XML documents to html or tab-delimited output. Using the standard DOM parser,
I eventually get an out-of-memory situation. So now I'm trying the DocumentSplitter to do a "mini" XSL transform on each <ROW>.
The good news is it works for small to medium size reports. But its slower and runs out of memory quicker.
Below is some of the relevant code. I also wrote associated classes to wrap the DocumentSplitter and to be the 'handler' that transfoms the XML when a <ROW> is found, and returns a string (see 'endElement' method below).
I'm freeing the CLOBS in PLSQL after reading them - do I need to free them from JVM memory seprately? If so, how can I do that if I need to pass them to PLSQL?
Thanks much,
Eric

XML diff - ignoring order

I'm working a project which basically involves producing a diff of 2 XML files. I recently discovered XDK and though that this would be the best way to do this.
However, after I implemented the XDK solution, I found that it makes a distinction between files with different node ordering, even when these are logically equivalent. The files I am operating on have no ordering guarantees. Is there a way to accomplish a logical (rather than physical) XML comparison using XKD? Or should I look at another product?

How are you processing the XML? Are you passing XML directly to merge or are you using XML Agent to transform the data to field nominated? Are you applying an XSLT?

XML Diff escape/unescape

When performing a diff between two xml files that may contain an escaped character i.e.
<FIELD>This & That</FIELD>
The resulting xsl does not leave the & escaped producing invalid xml.
<FIELD>This & That</FIELD>
Is there some way to instruct the method to escape reserved characters or is the only solution to parse through resulting xsl and escape characters after the fact.

Hi,
You might want to try CDATA or the attribute <disable-output-escaping="yes"/>.
Thanks,

Why to use xml ,sax api ,?

Dear friends
1> Can u please tell me why to use xml instead of html. When the developement is
easy & fast in html, then why peoples are going for xml.
2> Please tell me role of SAX api in relevence to XML.
3>What is difference between DOM & SAX.?
If possible spare few seconds to write to me.

1> Can u please tell me why to use xml instead of

HTML is only for presentations like web pages. XML, however, is use to define a new language like XHTML that is for presentations. But there are XML based language that is not for presentation, for example, XLink which allows elements to be inserted into XML documents in order to create and describe links between resources. All in all, XML is a much powerful language than HTML.
2> Please tell me role of SAX api in relevence to
XML.
Simplely put, SAX is a XML parser like DOM that is used to process XML data.
3>What is difference between DOM & SAX.?
Take a look at this: http://java.sun.com/webservices/docs/ea2/tutorial/doc/JAXPIntro.html
Hope this help.
