(un-)marshalling incomplete XML documents ?

Hi,
just wondering how XMLBeans deals with this issue, both in the specs and in the
current implementation. Is it possible to parse an XML document in which required
elements are missing, e.g. because some work in progress had been saved as XML?
I haven't worked with XMLBeans, but am curious if it goes beyond of what JAXB
offers here.
Please have a look at the respective discussion thread on the comp.text.xml newsgroup
(http://tinyurl.com/lhm8).

Yes, absolutely.
This is one of the key strong points of XMLBeans. Both in spec and
implementation, it is designed to (and does) bind to both valid and
invalid data correctly. It does so according to simple and robust
rules.
If you have a document where the data would be accessible via a
simple xpath /a/b/c/d, then with XML Beans the data is always
accessible via the bound getters doc.getA().getB().getC().getD(),
even if the document is structurally invalid (e.g., extra or missing
elements).
So XMLBeans's design guarantees the ability to bind to invalid data.
This makes for both faster, more understandable, and more robust
binding than other approaches that may require validity according to
a complex content model in order to bind.
XMLBeans is also capable of validating your data (complex content
models, etc - 100% of the spec) - but it is an important part of the
tool that your data does not need to be valid in order to be
bound. Binding only requires use of the proper tag names.
This model also makes for excellent loose-coupling and versioning
behavior, as was asked on a recent Q in this newsgroup:

Creating an XML document from a DTD in Java

Hi All,
I need help on the following requirement very badly. Pls help me.
I have a requirement to implement with java and XML. I am quit new to XML.Can any of you pls help me.
I have a DTD file. I need to generate XML document from it using java code. I have to use DTD as a template to generate my XML document.
After going through WEB sites, I understtod that, we have to user Java API JAXB for my requirement. But I could not find JAXB.jar anywhere.
I need to know the following inforamtion ....
1. Is my understanding of using JAXB for my requirement is correct?
2. Where can I get JAXB.jar?
3. What are the steps to create XML document from a DTD in Java?
If can give me a sample code for this would help me a lot.
Pls pls reply me. Your help is greatly appreciated.
Thanks in Advance.

Problem in digitally signing a particular element of an XML Document

hi all!!
I was trying to sign a particular element of an XML document using JSR105 (XML Digital Signatures) API.
For which i used +#xpointer(id('idvalue'))+ and +#idvalue+ as the URI for the reference i create as below :
Reference ref = fac.newReference("#xpointer(id('123')) ", fac.newDigestMethod(DigestMethod.SHA1, null), Collections.singletonList(fac.newTransform(Transform.ENVELOPED,(TransformParameterSpec) null)), null, null);
NOTE: Here 123 is the value of the attribute 'id' of the element i wish to sign in the input XML document.
But when i try to digest and sign the the above created reference, i get the following exception (which is strange! atleast for me!)
Exception in thread "main" javax.xml.crypto.dsig.XMLSignatureException: javax.xml.crypto.URIReferenceException: Can't resolve ID: '123' in ''

Any suggestions are very much welcome..

About DBD XML physical storage xml document

Recently I survey about BDB XML,
and I want to know how is it to storage the XML document, what format?? is like Natix storage like in page file ?? So if there are not index can be utilize, the system will use tree travel method to get query answer.
Or there are any document or technical manual support to introduction how DBD XML system internal storage format,how query process, how index build ....etc, because I ready some aboubt document but it major explain how to use the system (like API introduction).
Thanks very much !!

Hi Henry,
The physical nodes store a large amount of information in a record, including it's node ID, it's parent's node ID, it's level in the tree and the node ID of it's last descendant.
Ancestor-descendant relationships can be calculated using the node ID and last descendant ID as upper and lower bounds. Parent-child relationships additionally use the node level information. Sibling relationships need to use the parent's ID to check they have the same parent.
Navigation, on the other hand, uses other node IDs stored in the physical node, or implicit information. For instance if a node has children, it's first child is always the next node record stored. The last child ID is stored in the physical node, since this cannot be similarly calculated, as are the next and previous sibling node IDs.
If you are interested look in dbxml/src/dbxml/nodeStore/NsFormat.(hpp|cpp), which contains the marshaling code for the node storage format.

Hello Christian,
i know this reply is really late ;) I am actually the author of the blog post mentioned by @AnnaWY, the post she mentioned is in regards of a situation 'where everything' is how it should be. Basically, (i think) sometime administrator, or the
person who implements ITSM webservices makes an error, hence this script will not run. You will end up with that issue mentioned, in order to fix it, either you should contact the person who is responsible for that service, OR rewrite the wsdl for it yourself.
It might be a bit problematic, but, it is for sure doable, as in my latest blog post about this issue.
I am writing it here, because i also saw this page, while googling for explanation, i guess there are more people who are looking for this so here is the link to the explanation:

I hope that helps !

Using JAXB to edit XML documents

I am trying to understand how (and whether) JAXB can be used to make the following types of changes to an existing XML document. I know that I can EDIT an XML document using the set methods that are generated by JAXB (in conformance with the XML Schema), and then I create a Marshaller and marshall the root element object.
However, I have not figured out how to do any of the following:
(i) insert a new element
(ii) delete an existing element
(iii) reorder elements.
Here is an excerpt from an XML document:
<directory name="dir">
<file name="file1"/>
<file name="file2"/>
<file name="file3"/>
</directory>
The order in which the file elements appear is significant.
If I want to add a new file (file4), how would I do this? Where would it be added, at the end? What if I wanted to add it after file2?
If I want to delete file1, I don't know how to do that.
Finally, if I want to move file2 after file3, I don't know how to do that.
It seems as though I need access to the underlying com.sun.xml.bind.util.ListImpl (or similar collection object), which holds the actual file elements when JAXB unmarshals the xml file. However, this seems dangerous and I have gotten a concurrent access exception while trying to do something like this. (Another problem has to do with iterators, where I can't iterate through a list and then make a change to the list w/o messing up the iterator.)
If there are any technologies other than JAXB that might accomplish this, but that provide data binding, I would be happy to hear about it. (I could try SAX/DOM/JDOM/DOM4J or XSLT, I guess, but I like the data binding of JAXB.)

As is typical for me, I answered my own questions.
if you are outside of an iterator, you can simply use the:
add(object)
add(position,object)
remove(object)
methods of the List interface to add and remove elements from the list of elements.
Also, if you use a ListIterator, you can call the add() and remove() methods of ListIterator while iterating through the list.
In order to reorder elements in the list, use:
Collections.swap(list,pos1,pos2). Why this method is not built into the List interface itself is beyond me. This was only added in 1.4, btw.

Error while loading an XML document using a structured application

Hi,
I try to load an XML document using a structured application defined in the default structapps.fm
My code is shown down, extracted from the FDK API code sample.
Problem, I always have the same message :
"Cannot find the file named e:\xml\AdobeFrameMaker10\file. Make sure that the file exists. "
Where "e:\xml\AdobeFrameMaker10\" is my install directory.
So I assume that frame try to find the structapps.fm file but does not find it.
What else can it be ?
Does anyone knowns how to achieve this simple task using extendScript ?
Thanks for any comments, Pierre

    var filename = myLastFile.openDlg("Choose XML file ...", "*.xml", false);
    if (filename != null) {

Pierre,
Depending on the object "myLastFile", the method openDlg might not even exist (if the myLastFile object is not a File object, for instance). And I do not see any need for the myLastFile anyhow, as you are presenting a dialog to select a file to open. I recommend using the global ChooseFile( ) method instead. This will give you a filename as string in full path notation, or null when no file was selected in the dialog. I am not sure what your ExtendScript documentation states about the return value for ChooseFile, but if that differs from what I am telling you here, the documentation is wrong. So, if you replace the first lines of your code with the following it should work:
function openXMLFile ( ) {
    var filename = ChooseFile ( "Choose XML file ...", "", "*.xml", Constants.FV_ChooseSelect );
While writing this, I see that Russ has already given you the same advice. Use the symbolic constant value I indicated to use the ChooseFile dialog to select a single file (it can also be used to select a directory or open a file - but you want to control the opening process yourself). Note that this method allows you to set a start directory for the dialog (second parameter). The ESTK autocompletion also gives you a fifth parameter "helplink" which is undocumented and can safely be ignored.
Good luck

Problem replacing Null nodes with real values in XML documents...

Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
Our friends in Java land are insisting on passing data between Java and PL/SQL using fairly small XML documents (don't ask). I then need to extract the input parameter values and pass them, on to the stored procedures that actually do the work. These return a result which needs to be returned to the java layer in the output XML document.
Here is a cut down version of the input XML...
<ParameterList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Parameter>
<Id>1</Id>
<Result xsi:nil="true"/>
</Parameter>
<Parameter>
<Id>2</Id>
<Result xsi:nil="true"/>
</Parameter>
</ParameterList>
and this is an example of what I am expected to return...
<ParameterList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Parameter>
<Id>1</Id>
*<Result>SUCCESS</Result>*
</Parameter>
<Parameter>
<Id>2</Id>
*<Result>WARNING</Result>*
</Parameter>
</ParameterList>
i.e. I am expected to replace the value of the Result node with a string indicating the succes or otherwise of the underlying PL/SQL process.
I am extracting the input values using the DBMS_XMLDOM functions and naively assumed that DBMS_XMLDOM.SETNODEVALUE could be used to update the value in the Result node - It didn't work so I resorted to reading the documentation which revealed that it will not work for a null node.
Am I going to have to use XSLT to generate the output XML from the Input and incorprate the result? Or is there a simpler way?
I have used XSLT in Oracle before and still have the nervous tick...

One question, why do the dbms_xmldom functions return the Old value? I was expecting the returned value to be the updated node.

Performance issues with FDK in large XML documents

In my current project with FrameMaker 8 I'm experiencing severe performance issues with some FDK API calls.
The documents are about 3-8 MBytes in size. Fortmatted they cover 150-250 pages.
When importing such an XML document I do some extensive "post-processing" using FDK. This processing happens in Sr_EventHandler() during the SR_EVT_END_READER event. I noticed that some FDK functions calls which modify the document's structure, like F_ApiSetAttribute() or F_ApiNewElementInHierarchy(), take several seconds, for the larger documents even minutes, to complete one single function call. I tried to move some of these calls to earlier events, mostly to SR_EVT_END_ELEM. There the calls work without a delay. Unfortunately I can't rewrite the FDK client to move all the calls that are lagging to earlier events.
Does anybody have a clue why such delays happen, and possibly can make a suggestion, how to solve this issue? Thank you in advance.
PS: I already thought of splitting such a document in smaller pieces by using the FrameMaker book function. But I don't think, the structure of the documents will permit such an automatic split, and it definitely isn't an option to change the document structure (the project is about migrating documents from Interleaf to XML with the constraint of keeping the document layout identical).

FP_ApplyFormatRules sounds really good--I'll give it a try on Monday. Wonder how I could miss it, as I already tried FP_Reformatting and FP_Displaying at no avail?! By the way, what is actually meant with FP_Reformatting (when I used it I assumed it would do exactly what FP_ApplyFormatRules sounds to do), or is that one another of Lynne's well-kept secrets?
Thank's for all the helpful suggestions, guys. On Friday I already had my first improvements in a test version of my client: I did some (not all necessary) structural changes using XSLT pre-processing, and processing went down from 8 hours(!) to 1 hour--Yeappie! I was also playing with the idea of writing a wrapper to F_ApiNewElementInHierarchy() which actually pastes an appropriate element created in a small flow on the reference pages at the intended insertion location. But now, with FP_ApplyFormatRules on the horizon, I'm quite confident to get even the complicated stuff under control, which cannot be handled by the XSLT pre-processing, as it is based on the actual formatting of the document at run-time and cannot be anticipated in pre-processing.

Parse and output XML document while preserving attribute order

QUESTION: How can I take in an element with attributes from an XML and output the same element and attributes while preserving the order of those attributes?
The following code will parse and XML document and generate (practically) unchanged output. However, all attributes are ordered a-z
Example: The following element
<work_item_type work_item_db_site="0000000000000000" work_item_db_id="0" work_item_type_code="3" user_tag_ident="Step" name="Work Step" gmt_last_updated="2008-12-31T18:00:00.000000000" last_upd_db_site="0000000000000000" last_upd_db_id="0" rstat_type_code="1">
</work_item_type>is output as:
<work_item_type gmt_last_updated="2008-12-31T18:00:00.000000000" last_upd_db_id="0" last_upd_db_site="0000000000000000" name="Work Step" rstat_type_code="1" user_tag_ident="Step" work_item_db_id="0" work_item_db_site="0000000000000000" work_item_type_code="3">
</work_item_type>As you may notice, there is no difference in these besides order of the attributes!
I am convened that the problem is not in the stylesheet.xslt but if you are not then it is posted bellow.
Please, someone help me out with this! I have a feeling the solution is simple
The following take the XML from source.xml and outputs it to DEST_filename with attributes in a-z order
Code:
private void OutputFile(String DEST_filename, String style_filename){
     //StreamSource stylesheet = new StreamSource(style_filename);
     try{
          File dest_file = new File(DEST_filename);
          if(!dest_file.exists())
              dest_file.createNewFile();
          TransformerFactory tranFactory = TransformerFactory.newInstance();
          Transformer aTransformer = tranFactory.newTransformer();
          aTransformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
          Source src = new DOMSource("source.xml");
          Result dest = new StreamResult(dest_file);
          aTransformer.transform(src, dest);
          System.out.println("Finished");
     catch(Exception e){
          System.err.print(e);
          System.exit(-1);
    }

You can't. The reason is, the XML Recommendation explicitly says the order of attributes is not significant. Therefore conforming XML serializers won't treat it as if it were significant.
If you have an environment where you think that the order of attributes is significant, your first step should be to reconsider. Possibly it isn't really significant and you are over-reaching in some way. Or possibly someone writing requirements is ignorant of this fact and the requirement can be discarded.
Or possibly your output is being given to somebody else who has a defective parser which expects the attributes to be in a particular order. You could quote the XML Recommendation to those people but often XML bozos are resistant to change. If you're stuck writing for that parser then you'll have to apply some non-XML processing to your output to fix it up on their behalf.

Display xml documents - how to submit a feature request?

Safari is useless when it comes to render raw xml documents. You have to view the actual source to see the xml.
Is there an official way to submit a feature request for safari to apple? I would love to see something similar to what firefox does with xml. Safari is such a fast and nice browser, if it only could handle text/xml better...

As you said Safari simply shows all xml element content concatenated together. But no tags or attribute values. If the ContentType in the http header is set to text/xml Firefox shows an xml tree that you can nicely browse. I think IE5+ and Opera do that too. It is important to set the right content type though. Here is an example that shows nice in FF, but is unreadable in Safari:

Sure you can look at the source code, but the xml might not be pretty printed.

Displaying XML Document in new browser window

Hi,
I have a hyperlink on my page. When I click on it, it will open a new IE window and display xml document.
The new window is displaying some of the xml and at the end displaying the following:
The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.
End element was missing the character '>'. Error processing resource 'http://localhost:28080/benchmark/faces/displayXMLDocu...
However, I cut and paste the xml String where I write it to the HTTPServletResponse to XMLSPY and it displays correctly.
Please let me know.
Rgrds

Here are the steps:
1. I created page1 that has a hyperlink.
2. Hyperlink property are set to display page2 in a new window. (popup).
3. page2.prerender() method, I set the response to the following:
public void prerender() {
javax.faces.context.ExternalContext ec = this.getExternalContext();
HttpServletResponse response = (HttpServletResponse)ec.getResponse();
response.setHeader("Cache-Control","no-cache");
response.setHeader("Cache-Control","no-store");
response.setHeader("Cache-Control","must-revalidate");
response.setHeader("Cache-Control","max-age=0");
response.setHeader("Pragma","no-cache");
response.setHeader("Expires","0");
response.setContentType("text/xml");
response.setBufferSize(5000);
String xmlString = getRequestBean1().getBookingPnrDetailsXML();
try{
xmlString="<?xml version=\"1.0\" encoding=\"UTF-8\"?><root><test1>this is a test</test1><victor>Hello Victor</victor></root>";
PrintWriter out = new PrintWriter(response.getOutputStream());
log(xmlString);
out.print(xmlString);
}catch(IOException io){
System.out.println("" + io.getMessage());
io.printStackTrace();
4.page2.jsp code is the following:
<?xml version="1.0" encoding="UTF-8"?>
<jsp:root version="1.2" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:ui="http://www.sun.com/web/ui">
<jsp:directive.page contentType="text/xml;charset=UTF-8" pageEncoding="UTF-8"/>
<f:view/>
<ui:page binding="#{displayXMLDocument.page1}" id="page1"/>
<ui:html binding="#{displayXMLDocument.html1}" id="html1"/>
<ui:head binding="#{displayXMLDocument.head1}" id="head1"/>
<ui:link binding="#{displayXMLDocument.link1}" id="link1"/>
<ui:body binding="#{displayXMLDocument.body1}" id="body1"/>
<ui:form binding="#{displayXMLDocument.form1}" id="form1"/>
</jsp:root>
please let me know.

Error: No valid XML document received*_

Hi All,
We are connecting our CCMS system to NetWeaver J2EE engine on which E-Sourcing is running.
For this we registered java component and hosts in cen.
But we are getting error as : No valid XML document received
Please can anyone tell me how to overcome this error.
Thank you .
Regards
Mahesh

Hi,
Please re-read the answer from Marc carefully. He was in the exact same situation as yours:
- Monitored system: NW CE 7.1
- CEN: NW 7.01 (same as NW 7.0 EhP1)
The link you posted is for CEN with NW 7.3 and monitored systems from NW 7.02 (and up). Read the paragraph below the Caution sign:
If you want to centrally monitor any system with a central monitoring system with release SAP NetWeaver 7.0, this procedure is not applicable. In this case, follow the procedure described in the newest Monitoring Setup Guide for SAP NetWeaver 7.0 instead. You can obtain the Monitoring Setup Guide at the Internet address service.sap.com/operationsnw70 in the Monitoring area.
You should look for (and follow) the right Monitoring Setup Guide as mentioned.
Regards,
Dao

How to insert data into a table from an xml document

using the XmlSql Utility, how do I insert data into a table from an xml document, using the sqlplus prompt.
if i use the xmlgen.insertXML(....)
requires a CLOB file, which i dont have, only the xml doc.
Cant i insert directly from the doc to the table?
the xmlgen examples I have seen first convert a table to a CLOB xmlString and then insert it into another table.
Isnt there any other way?

Your question is little perplexing.
If you're using XML SQL Utility from
the commandline, just use putXML.
java OracleXML putXML
null

How can I access xml document from javascript whithin a JSP page

how can I access xml document from javascript whithin a JSP page?
I have a JSP that receives an XML document from a JavaBean, so I can access it within the entire JSP, but I need to access it from the javascript inside the JSP... and I have no idea how i can do this.
Thanks in advance!

The solution would only work on MS IE browsers, as other browsers do not support an XML DOM.
It can be done, but you would be stuck with using the Microsoft broswer. If that is acceptable, I have some example code, and a book recommendation.
