Parse XML in par structure.
Hi,
I want to parse an XML file which I want to store in my par project structure. Should I just store it in PORTAL-INF like portalapp.xml?
I tried doing this:
IResource xmlResource = request.getResource(IResource.XML,"PORTAL-INF/test.xml");
String url = xmlResource.getResourceInformation().getURL(request);
File f = new File(url);
FileInputStream fis = new FileInputStream(f);
......docBuilder.parse(fis);
My URL formed is /irj/WEB-INF/portal/portalapps/<project name>/PORTAL-INF/test.xmlhello
And the exception I get is :/irj/WEB-INF/portal/portalapps/<project name>/PORTAL-INF/test.xml (No such file or directory)
Am I doing this correctly?
Hi Prem,
First, I would advise to use the CODE marker of the SDN editor which makes code much more readable.
Second, you want to parse the XML on server side, retrieving the file directly from the file system. For this, the methods get[Public|Private]ResourcePath exists, see https://media.sdn.sap.com/javadocs/NW04/SPS15/ep/com/sapportals/portal/prt/component/IPortalComponentRequest.html for details.
Put the XML at some corresponding place (probably under the PORTAL-INF dir to make it private), use the method to determine the path on the file system, add your file name, and then create the File object with this full path.
Hope it helps

The above data structure uses a new node for each bit of core
information. It is well laid out and very readable by humans,
however a better structure exists when using Flash. The data
structure below makes more use of the attributes feature, speeding
the parsing process up. It takes longer for Flash to read 6
separate nodes, than it does 6 attributes of a node. The data
structure below is suited better for use with Flash.
How do I get it formated like this?

How to parse XML to Java object... please help really stuck
Thank you for reading this email...
If I have a **DTD** like:
<!ELEMENT person (name, age)>
<!ATTLIST person
id ID #REQUIRED
>
<!ELEMENT name ((family, given) | (given, family))>
<!ELEMENT age (#PCDATA)>
<!ELEMENT family (#PCDATA)>
<!ELEMENT given (#PCDATA)>
the **XML** like:
<person id="a1">
<name>
<family> Yoshi </family>
<given> Samurai </given>
</name>
<age> 21 </age>
</person>
**** Could you help me to write a simple parser to parse my DTD and XML to Java object, and how can I use those objects... sorry if the problem is too basic, I am a beginner and very stuck... I am very confuse with SAXParserFactory, SAXParser, ParserAdapter and DOM has its own Factory and Parser, so confuse...
Thank you for your help, YoHi, Yo,
Thank you very much for your help. And I Wish you are there...I'm. And I plan to stay - It's sunny and warm here in Honolulu and the waves are up :)
A bit more question for dear people:
In the notes, it's mainly focus on JAXB,
1. Is that mean JAXB is most popular parser for
parsing XML into Java object? With me, definitely. There are essentially 3 technologies that allow you to parse XML documents:
1) "Callbacks" (e.g. SAX in JAXP): You write a class that overrides 3 methods that will be called i) whenever the parser encounters a start tag, ii) an end tag, or iii) PCDATA. Drawback: You have to figure out where the heck in the document hierarchy you are when such a callback happens, because the same method is called on EACH start tag and similarly for the end tag and the PCDATA. You have to create the objects and put them into your own data structure - it's very tedious, but you have complete control. (Well, more or less.)
2) "Tree" (e.g. DOM in JAXP, or it's better cousin JDOM): You call a parser that in one swoop creates an entire hierarchy that corresponds to the XML document. You don't get called on each tag as with SAX, you just get the root of the resulting tree. Drawback: All the nodes in the tree have the same type! You probably want to know which tags are in the document, don't you? Well, you'll have to traverse the tree and ask each node: What tag do you represent? And what are your attributes? (You get only strings in response even though your attributes often represent numbers.) Unless you want to display the tree - that's a nice application, you can do it as a tree model for JTree -, or otherwise don't care about the individual tags, DOM is not of much help, because you have to keep track where in the tree you are while you traverse it.
3) Enter JAXB (or Castor, or ...): You give it a grammar of the XML documents you want to parse, or "unmarshall" as the fashion dictates to call it. (Actually the name isn't that bad, because "parsing" focuses on the input text while "unmarshalling" focuses on the objects you get, even though I'd reason that it should be marshalling that converts into objects and unmarshalling that converts objects to something else, and not vice versa but that's just my opinion.) The JAXB compiler creates a bunch of source files each with one (or now more) class(es) (and now interfaces) that correspond to the elements/tags of your grammar. (Now "compiler" is a true jevel of a misnomer, try to explain to students that after they run the "compiler", they still need to compile the sources the "compiler" generated with the real Java compiler!). Ok, you've got these sources compiled. Now you call one single method, unmarshall() and as a result you get the root node of the hierarchy that corresponds to the XML document. Sounds like DOM, but it's much better - the objects in the resulting tree don't have all the same type, but their type depends on the tag they represent. E.g if there is the tag <ball-game> then there will be an object of type myPackage.BallGame in your data structure. It gets better, if there is <score> inside <ball-game> and you have an object ballGame (of type BallGame) that you can simply call ballGame.getScore() and you get an object of type myPackage.Score. In other words, the child tags become properties of the parent object. Even better, the attributes become properties, too, so as far as your program is concerned there is no difference whether the property value was originally a tag or an attribute. On top of that, you can tell in your schema that the property has an int value - or another primitive type (that's like that in 1.0, in the early release you'll have to do it in the additional xjs file). So this is a very natural way to explore the data structure of the XML document. Of course there are drawbacks, but they are minor: daunting complexity and, as a consequence, very steep learning curve, documentation that leaves much to reader's phantasy - read trial and error - (the user's guide is too simplicistic and the examples too primitive, e.g. they don't even tell you how to make a schema where a tag has only attributes) and reference manual that has ~200 pages full of technicalities and you have to look with magnifying glas for the really usefull stuff, huge number of generated classes, some of which you may not need at all (and in 1.0 the number has doubled because each class has an accompanying interface), etc., etc. But overall, all that pales compared to the drastically improved efficiency of the programmer's efforts, i.e. your time. The time you'll spend learning the intricacies is well spent, you'll learn it once and then it will shorten your programming time all the time you use it. It's like C and Java, Java is order of magnitude more complex, but you'd probably never be sorry you gave up C.
Of course the above essay leaves out lots and lots of detail, but I think that it touches the most important points.
A word about JAXB 1.0 vs. Early Release (EA) version. If you have time, definitively learn 1.0, they are quite different and the main advantage is that the schema combines all the info that you had to formulate in the DTD and in the xjs file when using the EA version. I suggested EA was because you had a DTD already, but in retrospect, you better start from scratch with 1.0. The concepts in 1.0 are here to stay and once your surmounted the learning curve, you'll be glad that you don't have to switch concepts.
When parser job is done,
what kind of Java Object we will get? (String,
InputStream or ...)See above, typically it's an object whose type is defined as a class (and interface in 1.0) within the sources that JABX generates. Or it can be a String or one of the primitive types - you tell the "compiler" in the schema (xjs file in EA) what you want!
2. If we want to use JAXB, we have to contain a
XJS-file? Something like:In EA, yes. In 1.0 no - it's all in the schema.
I am very new to XML, is there any simpler way to get
around them? It has already take me 4 days to find a
simple parser which give it XML and DTD, then return
to me Java objects ... I mean if that kind of parser
exists....It'll take you probably magnitude longer that that to get really familiar with JAXB, but believe me it's worth it. You'll save countless days if not weeks once you'll start developing serious software with it. How long did it take you to learn Java and it's main APIs? You'll either invest the time learning how to use the software others have written, or you invest it writing it yourself. I'll take the former any time. But it's only my opinion...

How to parse XML using SAX Parser sequencially
I have a requirement to parse XML file sequencially. But I need to stop the parsing in-between for doing some processing.
Let me explain with example
I have a file with following structure.
<InputFile>
<Invoice>
<InvoiceNo = "Inv1"/>
<InvoiceDt = "12012002"/>
</Invoice>
<Invoice>
<InvoiceNo = "Inv2"/>
<InvoiceDt = "12012002"/>
</Invoice>
<Invoice>
<InvoiceNo = "Inv3"/>
<InvoiceDt = "12012002"/>
</Invoice>
For each Invoice node I need to process some activites. So I need to write a method which will open the XML file and parse and returns me a complete element from <invoice> to </Invoice> sequencially.
Please let me know whther some body has solution for this.
Manoj.If you're using a SAX parser then you can implement your code in the startElement(), endElement(), and characters() methods... have a look at the tutorial here:
http://java.sun.com/xml/jaxp/dist/1.1/docs/tutorial/index.html -
Parsing xml using DOM parser in java
hi there!!!
i don have much idea about parsing xml.. i have an xml file which consists of details regarding indentation and spacing standards of C lang.. i need to read the file using DOM parser in java n store each of the attributes n elements in some data structure in java..
need help as soon as possible!!!DOM is the easiest way to parse XML document, google for JDOM example it is very easy to implement.
you need to know what is attribute, what is text content and what is Value in XML then easily you can parse your document with dom (watch for space[text#] in your XML document when you parse it).
you get root node then nodelist of childs for root then go further inside, it is easy believe me. -
How to compare after parsing xml file
Hi,
following code, parse the input.xml file, counts how many nodes are there and writes the node name and its value on screen.
1) i am having trouble writing only node name into another file instead of writing to screen.
2) after parsing, i like to compare each node name with another .xsd file for existence.
Please keep in mind that, input.xml is based on some other .xsd and after parsing i have comparing its tag with another .xsd
Need you help guys.
thanks

what is the best method for loading external XML (with
inherent HTML) content into Flash and into the TextArea component?
here is the requirement:
i have an image loader and a TextArea together on the screen.
a "story" is loaded which will present a series of images (in the
image loading) associated with a corresponding text (in the
TextArea). a "story" has multiple image/text sections that are
navigatied through with FRWD/BACK buttons. any given section can
also have multiple sub-sections or "frames".
here is a diagram of the flow (in this case there would be 5
click throughs: 5 text/image sequences, but all contained only
within 4 sections):
http://jalaka.com/lab/ia/story_nav.jpg
below is my proposed sample XML structure. i want Flash to
recognize how many sections and frames within sections there are in
each story XML document - in order to generate a corresponding
navigation structure (a tab for each section). HTML content will be
immediate availble to loadinto TextArea as user move forward in
sequence with nav. and images references can also be preloaded into
available MC containers to be swapped into place as user navigates
forward in sequence. also need to read and store attributes for
each node in the XML to come up in MCs in sequence. and must also
be able to parse XML in a way to place simple HTML formatted
content (within XML) into the TextArea.
would Arrays be used?
<story title = "Story Title">
<section num = "1" title = "Section One Title" >
<frame image = "1.jpg" caption = "caption text
here"><b>Content</b><br><br>content
content content</frame>
</section>
<section num = "2" title = "Section Two Title" >
<frame image = "1.jpg" caption = "caption text
here"><b>Content</b><br><br>content
content content</frame>
<frame image = "2.jpg" caption = "caption text
here"><b>Content</b><br><br>content
content content</frame>
</section>
</story>Placing the XML into an array is a great plan. What you want
is each array element to be an object containing the section data.
Another plan is to use a List or Combox component. Again each
data property element would be an object containing the section
data. -
Does JMS parse xml content in TextMessages
Hi
I am working on WLS 6.1sp2 and I am using jms TextMessage type of message to
send XML messages from one subsystem to another. I have added an XML registry
for my version of XML parser. Now I do not have any entries for the entity declarations
nor for the parser entries in the registry.
When I send in an XML message in a TextMessage envelope I find the following
errors in the log.
<Jun 9, 2003 3:56:57 PM PDT> <Error> <XML> <Failed to parse given XML document.
Failed to retrieve PUBLIC id. The root element is required in a well-formed docu

<Jun 9, 2003 3:56:57 PM PDT> <Error> <XML> <Failed to parse given XML document.
Failed to retrieve PUBLIC id. The root element is required in a well-formed docu
ment.>
Now from the logs I understand that the message is being parsed and since the
parser does not find any PUBLIC ID or SYSTEM id it dumps the error, since I am
using schemas there is none of the PUBLIC and SYSTEM ids in my xml, also this
is not logged by any component of my subsystems, this is a weblogic XML Service
log and when I trace through the code I find that it comes up after the first
subsystem sends the message and before the second subsystem receives it.
The question then is does JMS parse XML content in TextMessages and if so how
can I disable that parsing?
Thanks
Sandeep
JMS does not automatically parse TextMessages. Check the XML declaration in
your application's deployment descriptors. That's often the source of this
error.
FYI, you can use XMLMessage for xml payloads. As far as I can remember, the
XMLMessage is an extension of the TextMessage with xml parsing built in.

Parse XML Inbound Interface file
What are SAP best practices to parse XML Inbound Interface file?
Currently we are parsing XML Inbound file with custom ABAP code, but it is somewhat cumbersome and requires maintenance.
We do not any middleware that can parse file for us.
Is there is any best way we can handle this without lot of maintenance..You can do it thro XLST..
Check this links..
Upload XML to internal table and vice versa in SAP 4.6C
/people/r.eijpe/blog/2005/11/10/xml-dom-processing-in-abap-part-i--convert-an-abap-table-into-xml-file-using-sap-dom-approach
YOu can do it through XLST. it is supported in ABAP from 4.7. you can create a XSLT, and read you XML, then CALL TRANSFORMATION to convert a XML into ABAP data structure.

Hello All,
There is a requirement for parsing of XML files to ABAP.
1.How do we pick an XML file from Application server and also from FTP server?
2.After picking the XML file how to parse that XML file to process it to create material master?Hi,
Ur scenario is File to R/3
For creating material master ..i guess there is IDoc named MATMAS.
U can make use of it and execute File to IDoc Scenario.

Generate database schema in XML from database structure
hi
I want to generate the entire database schema in XML from database structure. (Same feature is provided by Altova XMLSpy).
It would be great if there was some API that does the process of parsing the database structure and generating the XML automatically. A similiar feature is provided by Apache DdlUtils' API, but a stable version is not yet available...

Thanks in advance.Nikhil,
There is a wealth of information available on the Internet regarding the XML capabilities of the Oracle database.
Have you done an Internet search for "SQL XML Oracle"?

How to generate GUI code from parsed XML file?
hai,
I have to generate GUI code after parsing any configuration XML file as input.Now i have parsed my XML file and got its attributed and i want to get some idea of how to map the parsed XML attributes to the java code to build GUI code.Hello,
1. I like to create data type from a XML file structure, which contains the data structure ?
XML fields will need to be taken note of to see which is repeating or not. You can also load the XML into a third-party tool such as Altova XML Spy and then generate an XSD from there. You will need to import the XSDs into PI under external definitions. However, this does not guarantee business interoperability, as such, it is always best to ask the provider for the XSDs or WSDL. It will also save you a lot of time from guessing which fields are needed or not.
2. How to create custom node function in graphical mapping editor ?
In your graphical mapping editor, on the lowest left corner, there is an icon there that says Create New Function. You must take into account their return types:
1. Single Values = String
2. Queue/Context (no return type) thus resultList is used.
Hope this helps,

Importing/Parsing XML using SQL and/or PL/SQL
What is the recomended way of importing/parsing XML data using SQL and/or PL/SQL?
I have an XSD that defines the structure of the file, and an XML file that has the content in the appropriate structure. I have parsed (checked) the structure of the XML file using JDOM in my java application, and then passed it to a function in a package on the database as a CLOB.
What I need to do is parse the contents of the XML file that is passed into the function and extract the values of each XML element so that I can then do some appropriate validation before inserting and committing the data to the database (hence completing the import function).
A DBA colleague of mine has been experimenting with various ways of acheiving this, but has encountered a number of problems along the way, one of which being that he thinks that it is not possible to parse XML elements that are nested more than four levels deep - is this the case?
The structure of the XSD/XML that the database function needs to manipulate and import data from is very complex (and recursive by it's nature).
I would appreciate any suggestions as to how I can achieve the above in the most efficient manner.
Thanks in advance for your help

Oracle has comprehensive and varied support for XML, including a PL/SQL parser. -
Loading XML Document into Structured Storage
HI Everybody,
I am confronted with a BUG in Oracle which is being fixed but will last a long time. I have a relatively complex Schema with manifold includes, imports and inheritances which I can register successfully. The object-relational table is also generated. But loading the instance document with INSERT INTO... fails due to severe internal error. I have not yet tried SQL*Loader, however.
Please, does anyone know a safe alternative method to parse and load? Structured storage is mandatory because I need to retrieve individual elements and attributes. Instance documents are big, ca. 20 MB.
Thanks, regards
