Newbie: Read XML data in Java

Hello
I am very new to Java and XML and I have some basic questions.
I am creating some mailing lists in an XML tag where I have a identifier tag and then the e-mails as child tags. Something like this:
<mail-list id="1" name="friends">
<to-list id=1>
<receiver id="1" address="[email protected]"/>
<receiver id="2" address="[email protected]"/>
</tolist>
</mail-list>
I would like to create a method that receives the name of the mail list (ex:friends) and returns all the e-mail addresses that it contains.
How can I import data from a DOM to Java and return the text from a specific element or attribute?
Thanks

I would like to create a method that receives the name of the mail list (ex:friends) and returns all the e-mail addresses that it contains.You will need to traverse DOM document structure based on the filter //mail-list[@name="friends"] and then obtain each receiver id through nodelist object.
How can I import data from a DOM to Java and return the text from a specific element or attribute?http://java.sun.com/webservices/jaxp/dist/1.1/docs/tutorial/TOC.html : This link has it all + contains examples to explain concepts.

<Age> 24 </Age>
<City> chennai </Chennai>
</xml>
How do i read the data within the Name,Age, and City tags into variables in the ABAP Program?
Regards,
Thiru

if you decide to do in XSLT, I have a sample list here:
XML file like this:
<?xml version="1.0" encoding="UTF-16"?>
<F>
<P1>
<t_1>value1</t_1>
<t_2>testvalue</t_2>
</P1>
<P2>
</P2>
</F>
XSLT file like this:
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:sapxsl="http://www.sap.com/sapxsl" version="1.0">
<xsl:strip-space elements="*"/>

<T_1><xsl:value-of select="t_1"/></T_1>
<T_2><xsl:value-of select="t_2"/></T_2>
</ENTRY>
</xsl:template>

ABAP program like this:
DATA: BEGIN OF wa_upload,
text(255) TYPE c,
END OF wa_upload,
itab_upload LIKE TABLE OF wa_upload,
BEGIN OF wa_document,
t_1 TYPE string,
t_2 TYPE string,

If I tried with double ' (not '' ) it works with SQL through SQLPLUS but not with java. Indeed I have to store the data through my application
In java I get java.sql.SQLException: ORA-19102
Many thanks in advance,
Evanela

Thanks for your answer. I downloaded the JDBC AddressBook application and I found it very usefull. I was able to populate a datalist from a datasource and show it in my application. My problem still remains in the sense that I am unable to show the KPI data in a "custom node" meaning I woul like not only to extract directly the database record to a datalist object but also put the information of a single record in a textbok and a gauge and keep control of paging. I think this is done with the parser in the other examples but I can not figure out how to do it with MySQL and the new Desktop screen designer. Should I use a clip object? or is that managed already by the desktop screen designer? or where can I find an example with the functionality I need?.

Store XML data in java cache (hashmap as a key value pair)

Hi,
I have to store a xml file in java cache so that I can resue it .The flow is like this :
DAO layer reads database ,create an xml and sends to --> IBM MQ-->our java code should read this xml file over MQ and store it in a cache (preferably hashmap).The file contain unique id for every customer.
How can we achieve this.One way is to store the xml as an string as key is "id" and value is whole xml.Is this a good way or any other way is available.Please suggest.
Sample xml:
<Client>
<ClientId>1234</ClientId>
<ClientName>STechnology</ClientName>
<ID>10</ID>
<ClientStatus>ACTIVE</ClientStatus>
- <LEAccount>
<ClientLE>678989</ClientLE>
<LEId>56743</LEId>
- <Account>
<AccountNumber>9876543678</AccountNumber>
</Account>
</LEAccount>
- <Service>
<Cindicator>Y2Y</Cindicator>
<PrefCode>980</PrefCode>
<BSCode>876</BSCode>
<MandatoryContent>MSP</MandatoryContent>
</Service>
</Client>
Thanks
Sumit

A HashMap can work, but then still store the customer related data in a bean (and perhaps it will have some child objects as well, if for example the service subelement can repeat). So you get a HashMap of Customer objects, with the clientID as the index into the hashmap.

JAXB: Read XML data from a String?

Hi,
I get XML data not from file but as a string and I wanted to use JAXB to parse it and get my Java Objects.
The unmarshall methods wants an "InputStream", but "StringBufferInputStream" is deprecated, so that I don't know a way to use my String as InputStream.
Can someone give me a hint other then writing the data in a file first?

Hi FrankSch,
The unmarshall methods wants an "InputStream", but
"StringBufferInputStream" is deprecated, so that I
don't know a way to use my String as InputStream.
Can someone give me a hint other then writing the data
in a file first?Yes, the class StringBufferInputStream is deprecated, and the deprecation notice reads:
Deprecated. This class does not properly convert characters into bytes. As of JDK 1.1, the preferred way to create a stream from a string is via the StringReader class.
The JDK API usually mentions an alternative to the deprecated method/class and in this case, you should use java.io.StringReader. It has one constructor and should suite you nicely:
StringReader(String s) That way, you get an InputStream object; you can now use JAXB.
Hope this helps,

How to read XML data stored in CLOB in Concurrent prog Output

Hi All,
I'm trying to Generate the XML Data as concurrent Program output. I have a PL/SQL package which generated the XML data by using SQL/XML functions. I'm storing the generated XML data in a CLOB variable. But when i try to read the data using fnd_file.put_line(fnd_file.OUTPUT,XML_Data) it doesn't display data more than 32767 bytes.
Please help me out to understand what could be done to read the data in chunks. I have tried many logic's to print chunks of data but the output tags are either chopped off and errors out saying Tag not found.
My logic is as below:
v_handler:= DBMS_XMLGEN.newContext(v_xml_query);
--Sets NULL handling options
DBMS_XMLGen.SetNullHandling(v_handler, dbms_xmlgen.EMPTY_TAG ) ;
--Set special character handling
DBMS_XMLGEN.setConvertSpecialChars(v_handler, TRUE);
-- Specified whether to use an XML attribute to indicate NULLness of particular entity in the XML document
DBMS_XMLGen.useNullAttributeIndicator(v_handler,TRUE);
-- set Checking invalid chars
DBMS_XMLGEN.setCheckInvalidChars(v_handler, TRUE);
-- get the xml data as required
v_xml_data:= DBMS_XMLGEN.getXMLtype(v_handler);
SELECT XMLROOT(v_xml_data.extract('/*'),VERSION '1.0').getClobVal() into v_new_xml_Data from dual;
-- get the length of the xml generated
v_clob_len := dbms_lob.getlength(v_new_xml_Data);
FND_FILE.PUT_LINE(FND_FILE.LOG,'The Clob length is :'|| v_clob_len);
-- logic to process string more than 32767 Processing by each character
v_offset :=1;
while (v_offset <= v_clob_len)
LOOP
v_char := dbms_lob.substr(v_new_xml_Data, 1, v_offset);
IF (v_char = CHR(10))
then
fnd_file.new_line(fnd_file.output, 1);
else
fnd_file.put(fnd_file.output, v_char);
end if;
v_offset := v_offset + 1;
END LOOP;
FND_FILE.PUT_LINE(FND_FILE.LOG,'The offset is :'|| v_offset);
FND_FILE.NEW_LINE(FND_FILE.OUTPUT, 1);
THe above logic is for character by character which is a performance burden? Please let me know if there is any other work around for this

Hi,
Thanks for Replying. I have refered http://blog.oraclecontractors.com/?p=69 and then i added that piece of code. Basically, i'm trying to generate a report using XML publisher. To generate the XML data i'm writing a pl/sql package with SQl/XML functions. DBMS_XMLGEN would help me convert the XML Data as is. When the concurrent program runs this XML data will merge with RTF layout and generate required report. I'm able to generate the Report for data less then 32767 bytes. More than the limit i need to pass chunks of XML data to read as output. That's the reason i'm using fnd_file.output. But it reads only 32767 size at a time.
WHen i use the given logic, it works perfectly fine, but it loops for each character, for example if you have 30,000 characters it loops the same, which is peformance burden.
So i tried to write the logic of chunks but still i get the error that XML tag is not found or missing. I'm hoping this is very common issue, but after all my trails, i didn't find the right solution.
the other logic i tried was :
v_new_xml_data varchar2(32767)
v_iterations := CEIL(v_clob_len/v_chunk_length); -- v_chunk_length is 32767 and v_clob_length is length of the XML data stored inthe clob variable
For i in 0..v_iterations
LOOP
FND_FILE.put_line (fnd_file.log,'the loops v_pos :'||i||' and v_clob_length :'||v_clob_len);
v_new_xml_data := DBMS_LOB.SUBSTR ( V_XML_DATA,v_chunk_length,(i*v_chunk_length)+1);
FND_FILE.PUT_LINE (FND_FILE.OUTPUT,v_new_xml_data); -- read the output for every 32767 chunks
FND_FILE.PUT_LINE(FND_FILE.LOG, 'Chunk length is :'||((i*v_chunk_length)+1));
END LOOP;
FND_FILE.put_line (fnd_file.log,'out of loop');
FND_FILE.put_line (fnd_file.log,'length of new xml is '||v_clob_len);
Please, let me know if you need Further clarifications on the same.

Reading XML data from .pages file

Hi All!
I've been trying to get a script up and running, but frankly I'm lost. The script should read the date, lesson no, and name fields from a .pages file and then use that information to send an e-mail.
What I'm having a problem with is reading the data from the .pages file and I don't know what the best way to do it is because I'm still a novice at this.
So there are two ways I can think of:
1. Read directly from the Pages document when it is open. The problem with this is that it's a Pages template and it contains tables. Perhaps the easiest thing would be just to select certain cells directly from pages, but I have no idea how they're labeled or how to access them so I came up with a second idea. If you happen to know how to do this, I would greatly appreciate it.
2. Pages documents can be unzipped and one of the files is an xml file with a lot of tags and the data I need. I found the following post that talks about how to parse XML via an XSL stylesheet. After going through some tutorials, I got stuck because the xml itself in the Pages file is just a mess to me and I'm confused about which node to choose. In other xml docs you can see a clear, nicely laid out tabbed structure so you can at least figure out the path to the node you want. I stumbled across a nice script for TextWrangler which cleans up XML, but it just barks at the Pages file.
3. On top of that, I will need to use the name field and match that with an Address Book e-mail address. Should I change the template and make it into an address book field?
Thanks in advance,
Paul

The script should read the date, lesson no, and name fields from a .pages file and then use that information to send an e-mail.
Maybe you might want to try the following script:
tell application "Pages"
 activate
 tell foreground layer of page 1 of front document
 select (text box 1 whose vertical position < 0.5)
 tell application "System Events"
 keystroke "c" using {command down} -- ⌘C
 keystroke "a" using {shift down, command down} -- ⇧⌘A
 end tell
 set theText to the clipboard
 end tell
end tell
set TID to AppleScript's text item delimiters
set AppleScript's text item delimiters to tab
set theTextFields to text items of theText
set AppleScript's text item delimiters to TID
set {theDate, theLessonNo, theStudent} to {item 2, item 4, item 6} of theTextFields

Reading Excel data through java servlets

I am doing a project in jsp and servlet. During the project i have to read some excel data from the excel sheet and store them to DB2 database. While reading from the data from the excel sheet a problem occurred. I have used the poi package to read the data from the excel sheet and the code is correct and it reads the excel sheet. Now i just displayed the number of rows and cells in the excel sheet and while displaying the value of the every cell, the servlet displays only the address of each cell instead of displaying the value. Here i am attaching the code that i have used and the output of the servlet.
One more thing that i have noticed here is i just wrote a simple java program to read the excel data using the same steps that used earlier in the servlet. In this case the program displays the actual value of the excel cell.
Could you please help me to solve the problem.

double getNumericCellValue()
get the value of the cell as a number. For strings we throw an exception. For blank cells we return a 0.
public java.lang.String getStringCellValue()
get the value of the cell as a string - for numeric cells we throw an exception.
For blank cells we return an empty string.
For formulaCells that are not string Formulas, we return empty String

Hi Peter,
you are right,at high level i was able to figure at these things.
But i don't know how to implement it using jdeveloper.
It will be more helpful if you can give me detailed steps to do it.
Thanks
