Read xml String

hiya, when i read a ResultSet i can say
rs.getString ("Col Name here.");
well i wanna read the xml element also.
can i say ele.getString("ele Name hrer ?");

nope.
assuming ele contains only one text node, it would be something like this: ele.getFirstChild().getNodeValue()

How can i read XML string in a loop???

i changed xml file reader to xml string reader by
looking around this and other forums.
here is the code.
public class XMLTester2 {
 public static void main(String[] args) {
 String s = "<firsttag><secondtag>123</secondtag></firsttag>";
 java.io.Reader reader = new java.io.StringReader(s);
 org.xml.sax.InputSource source = new org.xml.sax.InputSource(reader);
 org.w3c.dom.Document doc = null;
 javax.xml.parsers.DocumentBuilderFactory fact = javax.xml.parsers.DocumentBuilderFactory.newInstance();
 try {
 javax.xml.parsers.DocumentBuilder builder = fact.newDocumentBuilder();
 doc = builder.parse(source);
 } catch (javax.xml.parsers.ParserConfigurationException pce) {
 } catch (org.xml.sax.SAXException se) {
 } catch (java.io.IOException ioe) {
 } finally {
 try {
 reader.close();
 } catch (java.io.IOException ignored) {
}i put this stuff into a loop, but i always ends up
having new in the loop.
 String inputLine = "Start";
 // define what's needed for XML messages
 Reader reader = new StringReader(inputLine);

 reader = new StringReader(inputLine);

 try {

 se.printStackTrace();
 } catch (IOException ioe) {
 System.out.println("IOException : " + ioe);
 } finally {
 try {
 reader.close();
 } catch (IOException ignored) {
 reader = null;i know putting new in the loop is VERY bad.
i gotto get ride of this new from the loop.
can anyone help me?

i know putting new in the loop is VERY bad.
i gotto get ride of this new from the loop.Don't design your application based on one-liners you heard somewhere. Do some timings to see if it matters. My guess would be that parsing an XML file would take a fair bit longer than creating a StringReader object. And you do need a new StringReader each time, they aren't reusable, so the alternatives are not obvious. And don't accept my guess about the timings, check it for yourself.

How do I read the XML string using Http response/request?

When my HTTP POST action is perform, the action will return me a XML string as shown in the link, https://www.neteller.com/gateway/netdirectv4.cfm?amount=150.00&net_account=458415554241&secure_id=896365&bank_acct_num=6789&currency=USD&merchant_id=1234&merch_transid=1102&merch_account=john123&custom_1=test123&custom_2=test123&custom_3=test123&test=1
The above XML string will be send back by one of the payment gateway.
How do I retrieve all the attribute name and value from the XML string so that it can be stored in my database?
The XML string will be as shown below:
<?xml version="1.0" encoding="ISO-8859-1"?><netdirect version="4.0">

Converting SQL Server text field containing XML string to XI XML via JDBC

Hello
My client has a SQL Server database containing a field of type Text which contains an XML string e.g.
<DispatchJob> <DispatchDateTime>2003-09-29T13:29:15</DispatchDateTime> <AssignedFSE>F118</AssignedFSE> <DispatchJobPurchase> <DealerID>14C5</DealerID> <DateOfPurchase>1997-10-01T00:00:00</DateOfPurchase> </DispatchJob>
I am using JDBC to access this but could someone please recommend the best and easiest solution for converting this string to XI XML for subsequent mapping to BAPI or IDOC or ABAP Proxy and transmission to SAP. There are other fields as well in the database table so thoughts at the moment are to use a normal graphical message mapping followed by an XSL mapping. Will an XSL mapping be able to do this and if so is that the best solution?
Also I need to do the reverse of this and take fields coming from SAP via BAPI,IDOC etc. and convert them to a single database table field as an XML string also via the JDBC adapter. What is the best way to do this. Could it be done simply with functions in the graphical mapping e.g. concatenate?
Thank you in advance.
Trevor

Hi Michal
Thanks for the prompt reply.
I was anticipating XSLT for reading from the SQL Server database and converting the XML string.
But how would you convert the individual fields from SAP into a single field as an XML string for storing in the SQL Server database? What approach would you use?
Regards
Trevor

Error Reading xml file

hello guys , i made a java program using jni to call a Com file , this com file will return an xml string , i am supposed to read that xml string and parse it
i made my code like the following
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          DocumentBuilder builder = factory.newDocumentBuilder();
          Document currentdocument = builder.parse(new File("simple2.txt"));
          //normalize the string representation
          currentdocument.getDocumentElement().normalize();
          String RootName = currentdocument.getElementById("IdValue").getNodeValue();
          jTextArea1.append(RootName);
now trying to parse that it gives me an enormous error which is
Invalid byte 1 of 1-byte UTF-8 sequence.
what is the problem

Using my crystal ball, it seems as if the .txt file created by the Com file is not UTF8 as you have specified or let default.

Reading a string.

Hi experts.
how can i read a string at a specified character.
For ex: i have astring like this.
str = 'YUGFHKGHKHDKHHHGJK8HJBFXJKKFKJFJKFHJH'.
so i have to read n.of charecters from starting of the string to charecter 8.
Not with search option.
Regards

Hi,
Thank you all.
I know all these but in my program it is not workig..Don't know why...
either split or search.Pls see the below sample code.
DATA : i_files like spflist occurs 0 with header line,
DATA: w_files LIKE LINE OF i_files.
data: str1(200) type c,
      str2(200) type c.
LOOP AT i_files INTO w_files.
    str = w_files-line.
    lin1 = STRLEN( str ).
    lin1 = lin1 - 1.(this is because there is one more '#' at the end of string)
    str = str+0(lin1).
    lin2 = STRLEN( str ).
    search str for '#'.
    split str at '#' into str1 atr2.
    w_files-line = str.
    MODIFY i_files FROM w_files.
    CLEAR lin1.
ENDLOOP.
Suppose here str contains:
str = '00000003379#212RegVNegNoticeHLA.aspx.xml'.
So i am getting sy-subrc = 4 after search.
and after split there are no values in str2..and str1 contains full string..
Can any body tell me what may be the problem..?
Regards

Extracting elements from an xml string - org.apache.xerces.dom.DeferredText

Hello all,
I am new to xml, and I thought I had a handle on things until I got this problem...I am getting an xml string from the body of an e-mail message, and then I am trying to extract elements out of it. Here is an example xml string:
<?xml version="1.0" encoding="UTF-8"?>
<filterRoot>
 <filter action="MOVE" bool="AND" name="My Saved Filter" target="Deleted Items">
 <condition attribute="TO" bool="AND" contains="CONTAINS">
 <value>[email protected]</value>
 <value>[email protected]</value>
 <value>[email protected]</value>
 <value>[email protected]</value>
 <value>[email protected]</value>
 </condition>
 </filter>
</filterRoot>I am trying to extract the <filter> element out and store it into a Vector of Elements (called, not surprisingly, filters). However, I am getting a class cast exception:
java.lang.ClassCastException: org.apache.xerces.dom.DeferredTextImplIt is being called from where I trying to extract the <filter> in this way:
 filterRoot = doc.getDocumentElement(); // get topmost element
 NodeList list = filterRoot.getChildNodes();
 Vector newFilters = new Vector();
 debug("There are "+list.getLength()+" filters in document");
 for(int i=0; i<list.getLength(); i++) {
 Node n = list.item(i);
 debug("Node "+i+" getNodeValue() is "+n.getNodeValue());
 Element temp = (Element)n;
 newFilters.add(temp);
 }Perhaps my question is, how do I correctly get hold of the <filter> node so that I may cast it as an Element?
thanks,
Riz

Yes, I already knew that it is not a bug.
But, I got next step problem.
I put "false" to "include-ignorable-whitespace" feature in xerces parser.
But, I still found unnecessary TextNodes in my parser object.
Feature link : http://xerces.apache.org/xerces-j/features.html.
I use xerces-2_8_0.
DOMParser parser = new DOMParser();
parser.setFeature("http://apache.org/xml/features/dom/include-ignorable-whitespace", false);
parser.parse(inputSource);
document = ps.getDocument();
System.out.println(document.getDocumentElement().getChildNodes().length()); // still wrong lengthIs tehre any example of usage this feature?
What is default defination of white-space "\n "(enter with one space) or " "(juz white space) or something else?
Thanks,

Is there any way to read XML directly from a Web Page ??

i have a url, which on sending request, shows XML in browser.
Now i need to read this XML in browser and then manipulate it according to my need and display it on another page.
actually the process is. :
1) i have to first retrieve an xml from other site. (XML will only be shown in browser)
2.)then i have to read the Xml and show it in according to my requirements.
Is there any way to read XML directly from a Web Page ??
is their logic to accomplish this.
e.g in Servlet i can do somewhat like this :
String wholeXml=Somemethod(url);
Please Advice

the average Java XML parser will accept an InputStream, so just open an URLConnection to the webpage, get the inputstream from it and feed that inputstream to the XML parser. If the URL has valid XML data, it will get parsed without problems.

How to get an XML string from a Java Bean without wrting to a file first ?

I know we can save a Java Bean to an XML file with XMLEncoder and then read it back with XMLDecoder.
But how can I get an XML string of a Java Bean without writing to a file first ?
For instance :
My_Class A_Class = new My_Class("a",1,2,"Z", ...);
String XML_String_Of_The_Class = an XML representation of A_Class ?
Of course I can save it to a file with XMLEncoder, and read it in using XMLDecoder, then delete the file, I wonder if it is possible to skip all that and get the XML string directly ?
Frank

I think so too, but I am trying to send the object to a servlet as shown below, since I don't know how to send an object to a servlet, I can only turn it into a string and reconstruct it back to an object on the server side after receiving it :
import java.io.*;
import java.net.*;
import java.util.*;
class Servlet_Message // Send a message to an HTTP servlet. The protocol is a GET or POST request with a URLEncoded string holding the arguments sent as name=value pairs.
public static int GET=0;
public static int POST=1;
private URL servlet;
// the URL of the servlet to send messages to
public Servlet_Message(URL servlet) { this.servlet=servlet; }
public String sendMessage(Properties args) throws IOException { return sendMessage(args,POST); }

 URLConnection conn=servlet.openConnection();

 conn.setDoOutput(true);

 out.close(); // ESSENTIAL for this to work!

public String toEncodedString(Properties args)
 StringBuffer sb=new StringBuffer();
 if (args!=null)
 String sep="";
 Enumeration names=args.propertyNames();
 while (names.hasMoreElements())
 String name=(String)names.nextElement();
 try { sb.append(sep+URLEncoder.encode(name,"UTF-8")+"="+URLEncoder.encode(args.getProperty(name),"UTF-8")); }
// try { sb.append(sep+URLEncoder.encode(name,"UTF-16")+"="+URLEncoder.encode(args.getProperty(name),"UTF-16")); }
 catch (UnsupportedEncodingException e) { System.out.println(e); }
 sep="&";
 return sb.toString();
}As shown above the servlet need to encode a string.
Now my question becomes :
<1> Is it possible to send an object to a servlet, if so how ? And at the receiving end how to get it back to an object ?
<2> If it can't be done, how can I be sure to encode the string in the right format to send it over to the servlet ?
