Converting into XML without using DOM

Hi there,
I need to generate a XML file on the fly, given a HashMap. It will be used later to feed into XSLT parser.
Instead of using DOM parser which is memory intensive, I am generating the XML by appending the necessary into a String. For eg:
StringBuffer st = new StringBuffer();
sb.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
sb.append( "\n" );
sb.append("<"+ transaction.getCode() + ">");
...........................so on
I tried to gain resources in the book, but every example will actually use DOM to build a XML file.
I am just thinking what is the repercussion if i do not use DOM.
Could anyone please advice.
Thanks.

None really, if you don't need to walk the tree and have random access. Some find it hard to read / maintain, but I don't mind it. If you are just outputting to XSLT, what you are doing will work fine.

Updating XML file using DOM parser

Hi,
Can someone help me, how to update following XML file using DOM parser.
The following is my XML file.
<students>
     <student>
          <id>1</id>
          <name>abc</name>
     </student>
     <student>
          <id>2</id>
          <name>xyz</name>
     </student>
     <student>
          <id>3</id>
          <name/>
     </student>
     <student>
          <id>4</id>
          <name>ijk</name>
     </student>
     <student>
          <id>5</id>
          <name></name>
     </student>
</students>Consider, I will input 2 fields, ie., id & name. For the matching Id, the name has to be updated.
Though, I have achieved this, but I am unable to update the value for 3rd record, & 5th record ie., id=3 & id=5. Since, these are blank.
Thanks.

Some <name> elements have a child node which is a text node. From what you say it appears you know how to change those text nodes.
The other <name> elements don't have any child nodes. But you want one. This suggests to me that you need code that creates a text node and adds it to the <name> element as its child.

Problem writing xml file using DOM

Hi,
I am trying to write a xml file using DOM. I am using xalan 2.5, xerces 1.4.4, jdk 1.3.1 in JRun 3 on windows.
The code where I get exception :
               TransformerFactory tFactory = TransformerFactory.newInstance();
               Transformer transformer = tFactory.newTransformer();
               transformer.transform(new DOMSource(doc), new StreamResult("pr.xml"));
I get the runtime error as follows:
javax.servlet.ServletException: null
java.lang.NoSuchMethodError
     at org.apache.xml.utils.DOM2Helper.getNamespaceOfNodeDOM2Helper.java:342)

     at org.apache.xalan.transformer.TransformerIdentityImpl.transform(TransformerIdentityImpl.java:343)
Thinking it is because of classpath, I placed xalan 2.5, xerces 1.4.4 jar files in jrun admin lib directory and in server lib directory as well. Still getting the same error.
Any suggestion?
Thanks in advance

xalan is included in JRun 4. However JRun 3 does not.
However I tried with the same code in JRun3 in different system. The error is completely different. I understand this is because of different version of files. trying to solve ;)

Reading files and converting into xml structure

Hi,
In my application a client requests for the folder structure information to a server through RMI. The server needs to read files and folders on local machine and convert it into some structure (I am thinking of using xml) and send it back. For eg: I am planning to have Server send back something like:
<directory name = "parentdirectory">
<file name = "abc.jpg"/>
<file name = "def.bmp"/>
<directory" name = "subdirectory">
<file name = "hij.jpg"/>
<file name = "klm.bmp"/>
</directory>
</directory>
It is just the names of the files I am interested in and not the contents. Is this a good approach of sending back the data as a string containg xml definition. Is there any better appproach in terms of performance, memory etc? I am currently planning on using DOM for construction of this structure. Is there a source code for reading and converting the folder structure into xml. Just for your information, the clients gets this information and shows it as a tree structure on the GUI.
Thanks!!!!

Is this a good approach of sending back the data as a string containg xml definition. It'll work.
An alternative, more direct approach is to build a memory representation and send this as argument/return value of an RMI call. You'd need to write classes MyDirectory and MyFile; MyFile has just a name; MyDirectory has a name and a collection of MyDirectory and one of MyFile. Make these classes implement Serializable and you can send them over RMI.
The effort to write those trivial classes would be less than to implement XML encoding/decoding, and also in terms of runtime performance and memory it will be hard to beat Java's serialization with anything XML-based. In this case I doubt performance/memory are relevant considerations though.
If for some reason I'd go for sending XML Strings anyway, I wouldn't do the encoding/decoding myself; I'd use XStream to convert Java classes to/from XML and still end up writing the above two classes and be done.
Sorry if you wanted a simple yes or no :-)

How to remove element namespaces in XML file using DOM or SAX?

Hi Guys,
I developed a JAVA mapping in XI to add name spaces for XML file, after mapping,name spaces xmlns="http://www.mro.com/mx/integration" and xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" were added correctly, but for some nodes, such as <Header> and <Content>, a name space xmlns="" was added automatically.Please check below files to compare.
It looks like be added automatically by XI. I didn't process anything for these nodes in JAVA program.
Now the issue is, how can I remove these redundant namespaces? Such as xmlns="".
Can I remove them using DOM or SAX in JAVA Mapping?
Thanks in advance.

Hi Milan,
Thanks for your replay.
Actually when I used module XMLAnonymizerBean to convert namespaces, the header of XML, such as <?xml version="1.0" encoding="UTF-8"?> was converted to format <?xml version='1.0' encoding='UTF-8'?>, quote was converted to single quote. Although I set parameter anonymizer.quote = ", it still didn't work, single quote appeared instead of quote.
I'm not sure why this happened. Can anyone help to clarify this?
Thanks

Store and load objects to XML files using DOM

Hello everybody,
a quick question for all of you.
I'm designing a desktop application which requires a lot of custom objects to be stored into XML files and later reloaded from them. I'm planning to use DOM, creating an interface like this:
public interface StorableAsDom
// Create an object from a DOM tree
static Object createFromDom(org.w3c.dom.Node root) throws InvalidDomException;
// Get the DOM tree for an object
org.w3c.dom.DocumentFragment getDomTree(org.w3c.dom.Document doc) throws DOMException;
Then, every class which needs to be saved should implement the above interface. This way everything works fine.
My question is: do you know any available java package which already provides similar functionalities?
I'd like not to reinvent the wheel if I can; time is always a critical factor.
Thanks in advance to all of you.
Cheers
marcocaco

Hi,
When I need object -xml binding, I usually have two methods -
one for reading & one for writing (the "VOs" below stands for "Value Objects" [getters/setters & empty constructor only]):
READ: loadXML (= XML2VOs)
1.XML2DOM - this method can be generic
2.DOM2VOs - populate your VOs from the DOM just obtained in 1.
WRITE: saveXML (=VOs2XML)
1.VOs2DOM - create a new DOM document from your VOs' fields.
2.DOM2XML - this method can be generic
It would be nice (but dificult & not very elegant) to make DOM2VOs & VOs2DOM generic. If such methods will be written, they should be combined with the XML2DOM & DOM2XML (resp.) & then you would have two generic methods XML2VOs & VOs2XML... (Alternativelly, you can get Sun's JAXB package which does object-xml binding but this is not part of the JDK 5)
If what I have outlined above sounds like what you want to do, let me know if you want more details (eg. how the DOM2VOs would be implemented etc)...

Problem in parsing a xml string using dom parser

i want to parse a Xml String using a Dom parser......the parse function in dom parser takes only input stream as argument.......so i made the code as
InputStream inputstream = new StringBufferInputStream(XmlData) ;
InputSource inputSource = new InputSource(inputstream );
but saxexception is coming and also warning called
"java.io.StringBufferInputStream in java.io has been deprecated"
please help me.........

i want to parse a Xml String using a Dom
parser......the parse function in dom parser takes
only input stream as argument.......This is not true of the DOM parser in Java 1.4. So you might want to get rid of your old parser and replace it by something more current. Or perhaps you are using 1.4 and you just didn't read all of the API docs.

Can't convert stack XML file using report RPT_MOPZ_COPY_STACK for upgrade

Hello Colleagues/ SAP Experts,
Here is a background. 2 weeks ago, we have generated an XML stack file using MOPZ in solman 7.1 for the following systems (P6D which is DEV,
P6Q which is quality, P6R which is regression and P1P which is production). We were at our technical cutover rehearsal phase and the system that we were rehearsing was P6R. But AFTER our technical cutover, a new java component, which is seeburger as2 adapter, was installed in P1P, PRODUCTION. Thus, the landscape of P1P has changed as a new component was introduced and we believe that the generated XML file 2 weeks ago will no longer be valid for P1P. Instead of generating another xml file thru mopz for P1P, we would like to use report RPT_MOPZ_COPY_STACK_XML to convert the XML file OF P6R to map it toP1P. I have uploaded P6R XML and the target is P1P. So as you can see, P6R XML (source) --> P1P target.
Actions already done are the following:
1) Fulfilled and followed the resolution in note: 1711612
RPT_MOPZ_COPY_STACK_XML Report Troubleshooting
2) SAP-OSS is working in SM59
Basically, program RPT_MOPZ_COPY_STACK does not convert the Regression system's xml to the target, which is production. Kindly see attached screenshot. *the screenshot shows only 1 component in error but upon clicking the 'next difference' button, it will still show other components. I have checked my lmdb settings, will there be workaround for the issue?
Regards,
Meinard

Hello Divyanshu Srivastava / Reagan Benjamin ,
Thank you for your replies. Yes I noticed that a new higher patch for one java component was already present when I have regenerated recently for production using mopz. Anyways, SAP has returned a message wherein they edited the xml file themselves. Most of errors were eliminated only error was kernel versions was not matched. We need to upgrade kernel of our production and test if it works. Hopefully it will. Thanks though at first we did not edit the xml as according to one sap note I read it will not be supported by SAP. Closing this thread now
