Read a XML file and store an element to a String

Hello,
I'm looking for a solution to load an XML file (see below), read all elements and store the first of them (the first "description" element) in a String variable.
Should I load the file in a Node variable?
What is the best solution?
The XML file looks like:
<document>
<typeOfWorkstation >
<item id="desktop">
<description>Desktop</description>
</item>
<item id="laptop">
<description>Laptop</description>
</item>
<item id="other">
<description>Other configuration</description>
</item>
</typeOfWorkstation>
</docuement>
All suggestions will be greatly appreciated
Thank you
Sylvain

no example, uh? the tutorial is packed with code samples
this will get you started:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new File("c:/folder/data.xml"));

I need to store and retrieve data into a AL32UTF8 database without losing language attributed.
I am using DBMS_XMLDOM.getnodevalue (); to fetch the XML stored in a CLOB column
But the package returns VARCHAR2 .How do i return NVARCHAR2 so that i can store Multilingual data
DBMS_XMLDOM.GETNODEVALUE(
n IN DOMNode)
RETURN VARCHAR2;
Or is there an easier way around using XMLTYPE

Reading XML file and skip certain elements/attributes??

Hi folks!
Suppose I have a XML file looking like this:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE dvds SYSTEM "DTDtest.dtd">
<dvds>
<dvd>
<title>
Aliens
</title>
<director>
James Cameron
</director>
<format>
1.85:1
</format>
</dvd>
<dvd>
<title>
X-Men
</title>
<director>
Bryan Singer
</director>
<format>
2.35:1
</format>
</dvd>
</dvds>
In my Java application I want to read this XML file and print it on the screen (including all tags etc). So far, so good. BUT, if I want to skip certain elements, i.e. all information about the dvd 'X-Men', how am I supposed to do this? In other words, I would like my app to skip reading all information about X-Men and continue with the next <dvd>... </dvd> tag. Is this possible?
My code so far is from the XML tutorial from Sun and it looks like this:

try {

A possibility that comes to mind is to create an XSLT script to do whatever it is you want - and call it from inside the program. The XSLT script can be stashed inside your .jar file by using getClass().getClassLoader().getResource("...")

Reading A xml file and sending that XML Data as input to a Service

Hi All,
I have a requirement to read(I am using File adapter to read) a xml file and map the data in that xml to a service(schema) input variable.
Example of xml file that I have to read and the content of that xml file like below:
<StudentList>
 <student>
 <Name> ravi</Name>
 <branch>EEE</branch>
 <fathername> raghu</fathername>
 </student>
<student>
 <Name> raju</Name>
 <branch>ECE</branch>
 <fathername> ravi</fathername>
 </student>
<StudentList>
I have to pass the data(ravi,EEE,raghu etc) to a service input varible. That invoked Service input variable(schema) contains the schema similar to above schema.
My flow is like below:
ReadFile file adapter -------------------> BPEL process -----> Target Service.I am using transform activity in BPEL process to map the data from xml file to Service.
I am using above xml file as sample in Native Data format(to create XSD schema file).
After I built the process,I checked file adapter polls the data and receive the file(I am getting View xml document in EM console flow).
But transform activity does not have anything and it is not mapping the data.I am getting blank data in the transform activity with only element names like below
---------------------------------------------------------------------------EM console Audit trail (I am giving this because u can clearly understand what is happening-----------------------------------------------------
 -ReceiveFile
 -some datedetails received file
 View XML document (This xml contains data and structure like above xml )
 - transformData:
 <payload>
 <InvokeService_inputvariable>
 <part name="body">
 <StudentList>
 <student>
 <name/>
 <branch/>
 <fathername/>
 </student>
 </StudentList>
 </part>
 </InvokeService_inputvariable>
'Why I am getting like this".Is there any problem with native data format configuration.?
Please help me out regarding this issue as I am running out my time.

Hi syam,
Thank you very much for your replies so far so that I have some progrees in my task.
As you told I could have put default directory in composite.xml,but what happenes is the everyday new final subdirectory gets created in the 'soafolder' folder.What I mean is in the c:/soafolder/1234_xmlfiles folder, the '1234_xmlfiles' is not manually created one.It is created automatically by executing some jar.
Basically we can't know the sub folder name until it is created by jar with its own logic. whereas main folder is same(soafolder) ever.
I will give you example with our folder name so that it would be more convenient for us to understand.
1) yesterday's the folder structure : 'c:/soafolder/130731_LS' .The '130731_LS' folder is created automatically by executing some jar file(it has its own logic to control and create the subdirectories which is not in our control).
2) Today's folder structure : 'c:/soafolder/130804_LS. The folder is created automatically(everytime the number part(130731,130804).I think that number is indicating 2013 july 31 st like that.I have to enquire about this)is changing) at a particular time and xml files will be loaded in the folder.
Our challenge : It is not that we can put the default or further path in composite.xml and poll the file adapter.Not everytime we have to change the path in composite.xml.The process should know the folder path (I don't know whether it is possible or not.) and everyday and file adapter poll the files in that created subfolders.
I hope you can understand my requirement .Please help me out in this regard.

Read a property file and store it in a hashmap

Hi,
I have tried to read a property file and store it in a hashmap. The property-names should be stored in keys and the property-values (after = symbol) in values of the hashmap. any ideas? Is it possible to do this?

mandy2001ir wrote:
yes, but I need the hashmap for another reason. Actually I'm trying to use the properties file to have a dynamic hachmap. I don't want to change the code anytime I want to put a value in the hashmap. therefor I write the "keys" and "values" in a property file and change the property file. That's the reasn why we have property files, isn't it?What's a "dynamic hashmap"? There's no other kind! Whenever someone starts bandying around the word "dynamic" in contexts like this, it usually means there's a simple solution to their problem, that they haven't yet considered, or mistakenly don't believe is applicable to them, because of this "unique" need for something "dynamic". Trust me, you just need to load the file using a Properties object, and you're done. Properties extends Hashtable, which is virtually the same thing as a HashMap. Properties does exactly what you want it to. it's the very reason the class exists
Have you even looked at the javadoc for java.util.Properties yet? I'm betting not, because if you had, you'd know exactly what I meant. And since you haven't, I'm at a bit of a loss as to how you can so easily dismiss the class as useless, despite existing to do exactly what you need

Read in XML file and spit out specific element

Hi all i wonder if someone could give me a hand. I've got some code (below) which reads in an xml file and spits out the contents of the file. Thats fine and dandy, however what i want to be able to do is specify which element to spit out, which i'm not sure how to do. So say i had the following xml file:
<?xml version="1.0"?>

Reading from XML file and updating the table ????

Hi
I have package which reads the hier.XML file and does Update inserts into the 5 tables
i have table called MAIN_tbl with the column cur_date.
The package kicks if this cur_date is one day less than the hier.XML file DT.
Currently i m manually checking this date's to make sure the Main_tbl cur_date is n sync with
hier.XML file DT.
for example :- hier.xml file DT is "20091020" then main_table cur_date should be 10/19/2009
in order to kicks of the pakage.
what i m looking to do ??
compare the hier.xml DT with the main_table cur_date,
if cur_date is -1(Preivous day) of hier.xml DT then run hier_pkg(Package)
if not then update main_table cur_date to -1(previous day) of the hier.xml DATE
Then later write the above logic to update the main_table in a procedure, and
then call the package from the procedure.
below are the top few lines of the hier.XML file which is relevant to the one which we are trying to do
<?xml version = '1.0'?>
<HIER_POSTING num ="111" HIER_TYP="CD" DT="20091020" Global="Y">
FYI : The hier.XML file is located in UNIX space.
How do i accomplish this. any idea ????
Thank you so much in advance. For giving a thought on this problem!!!

Any thought on this guys ???
Thanks!!

Reading an XML file and write the contents to another xml file in java

Hi,
I am new to xml parsing.My requirement is that I am getting a message (xml) using ibm MQ in the ByteArrayInputStream format.I have to read this xml message and write to another file.
I am creating a POC for this.
First I used simple reading and writing concept but the output is "java.io.FileInputStream@3e25a5 "
Sample xml file
- <Client>
<ClientId>1234</ClientId>
<ClientName>STechnology</ClientName>
<DTU_ID>567</DTU_ID>
<ClientStatus>ACTIVE</ClientStatus>
- <LEAccount>

<Cindicator>Y2Y</Cindicator>
<PrefCode>980</PrefCode>
<BSCode>876</BSCode>
<MandatoryContent>MSP</MandatoryContent>

</Client>
code:
import java.io.ByteArrayInputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
public class ByteArrayInputStreamToXml {
 public static void main(String srg[]) throws IOException{
 InputStream inputStream= new FileInputStream("C:\\soft\\test2\\sample1.xml");
 byte currentXMLBytes[] = inputStream.toString().getBytes();
 ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(currentXMLBytes);
 OutputStream out = new FileOutputStream("C:\\soft\\test\\data.xml");
 int read=0;
 byte[] bytes = new byte[1024];
 while((read = byteArrayInputStream.read(bytes))!= -1){
 out.write(bytes, 0, read);
 out.write( '\n' );
 inputStream.close();
 out.flush();
 out.close();
 System.out.println("New file created!");
Please suggest me how can I use DOM/SAX parser ,I can see several code on net for reading xml file using SAX/DOM parser but writing an xml file after reading it using ByteArrayInputStream I am not getting .A help through some example Link will also be helpful for me.
Thanks

Read of XML file and post to IDOC

Hi
I'm working on a WAS620 and need to read an XML file from a customer, extract the fields needed and post these via IDOC ORDERS01. My problem is HOW to read the XML file? Can anyone give me the steps involved/links to examples etc - I have not processed XML files via ABAP before.
The file is posted to a shared folder and the ABAP I am about to develop will pick up this file.
The file is NOT in IDOC/XML format but the customers own format
Hope someone can help me asap.
Thanks all in advance
/Bo

Hi,
I would like to extend this question for WAS620 and reading a proprietary customer specific XML file/data that is send via HTTP to SAP WAS.
Q1: What is the best way to read this HTTP sent XML data (as it is, without transformations) into ABAP?
Q2: What is the appropriate handler to use in the ICF object?
Thanks all in advance

Read an XML file and send it to client

Hi,
I'm introducing to servlet development and I'm trying to do some AJAX calls. The client side is implemented, but I have some troubles on the server side. I want to open an XML file and send it to the client. How can I do that? Any special header?
I have implemented this test in PHP, so you can imagine what I would like to do:
if ($type == "xml"){
 $xml = "";
 $file = fopen ("file.xml", "r");
 while (!feof ($file)){
 $xml .= fgets ($file, 4096);
 fclose ($file);
 header ("Content-type: text/xml; charset=ISO-8859-1");
 echo $xml;
}The XML file is:
<?xml version='1.0' encoding='ISO-8859-1'?>
<users>
 <user>
 <name>Pepe</name>
 <age>18</age>
 </user>
 <user>
 <name>María</name>
 <age>21</age>
 </user>
</users>Thanks.

Not very useful:(.
This is my code:
PrintWriter out = null;
 try{
 String type = request.getParameter ("type");
 if (type.equals ("xml")){
 response.setContentType ("text/xml; charset=ISO-8859-1");
 out = response.getWriter ();
 String xml =
 "<?xml version='1.0' encoding='ISO-8859-1'?>" +
 "<users>" +
 "<user>" +
 "<name>Pepe</name>" +
 "<age>18</age>" +
 "</user>" +
 "<user>" +
 "<name>María</name>" +
 "<age>21</age>" +
 "</user>" +
 "</users>";
 out.println (xml);
 }finally{
 out.close ();
 }This code works. The servlet send back the xml and the client shows the content but, as you can see, i'm not reading the xml file. So my problem is on reading the xml file as a plain text. My code is this:
response.setContentType ("text/xml; charset=ISO-8859-1");
 out = response.getWriter ();
 String xml = "";
 FileReader fr = null;
 BufferedReader br = null;
 try{
 fr = new FileReader (new File ("file.xml"));
 br = new BufferedReader (fr);
 String linea;
 while ((linea = br.readLine ()) != null){
 xml += linea;
 //System.out.println (linea);
 fr.close ();
 }catch (Exception e){
 e.printStackTrace ();
 }But now I get an Exception File not found. The xml file is in the web directory (I'm using net beans 6.8). Where I have to put the file?
Thanks.

here is the code template.......

this.reader = reader;
nextChar();

c = (char)reader.read();

return new Token(type, text.toString());
Can someone please provide me the logic for the code please........... here is the complete link of the excersie http://www.antlr.org/wiki/display/CS652/Lexer+for+XML
Many Thanks

Can someone please provide me the logic for the code please..........The logic is pretty well spelled out for you in the description of the assignment and the outline for the code you provided. If you mean
Can someone please do my homework for me....The answer to that is usually yes, someone can do your homework for you, but no, they usually won't actually do it for you.
However, if you are really stuck on what to do, you should consider:
 if ( start of a tag ) {How would you know that you are at the start of a tag? Once you can answer that, the rest sort of works itself out as long as
 // scarf until end of tagyou realize what it means to 'scarf' and how to determine when an end-of-tag is reached (hint, very similar as to how to determine if you are at the start-of-tag).
