How to read xml-stylesheet Processing Instruction from XML using DOM Parser

Hi,
I am trying to read an xml that contains xsl stylesheet PI using DOMParser. The parse() method reads the entire contents of the XML except the PI instruction. Below is the XML I am using to read
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet href="../../../lang/en-us/style0/usc_profile.xsl" type="text/xsl"?>
<Oblix oblang="en-us" xmlns="http://www.oblix.com/" xmlns:oblix="http://www.oblix.com/">
<ObProfile>
</ObProfile>
</Oblix>
Can anyone let me know if there are any propery settings to be done for the DOM parser before parsing?. If so, what is the property to be set?.
Thanks in Advance

A COTS product builds the XML and inserts the respective xsl (xml:stylesheet) file name to be used for transforming the xml. I am trying to interrupt this xml and make some updations on an element and finally send the updated xml to the stream.
For the above process, I parse the input XML using DOMParser and update the elements (some internal elements). While I view the final XML that would be passed to the stream, I found the <?xml-stylesheet... PI is missing.
I somehow managed using a temp fix by doing the below. I manually pulled the PI using document.getFirstChild().getNodeValue() and reconstructed the PI and inserted it to the outgoing XML. This needs to be done every time. This might run into problems when more than one PI is used in the XML.
If the parsed XML could get the PI along with it the above problem could be resolved.
Is there any property that could be set on the parser (prior to parsing) to resolve the issue?.

How to create DTD from XML using DOM

Hi,
Is there a way to create a corrosponding DTD of a xml-file using DOM. I have a XML-file that's pretty huge I want to create a DTD for that XML-file using DOM. Can anyone plz. lead me how to do this. I tried to use XMLSpy to convert the XML into DTD but the resulting DTD is not correct. Is there a way to create the DTD using DOM.
Any help is really appreciated. Thanks

When you say you are trying to convert XML to DTD, do you mean you are trying to convert a XSD (schema) to a DTD, or that you are trying to create a schema that corresponds to a given XML document.
Realize that DTDs are not very powerful. XSD documents allow for much more detail. I don't have a proof, but I'm absolutely confident that any DTD can be expressed as a schema but not all schemas can be represented as a DTD. In other words, DTDs are not worth the trouble, in my opinion.

Remove tags from XML using transformation

Can anybody tell me how to remove empty tags using xsl transformation.
<App_Data App="MOD" Name="Metadata_Id" Value="SP1282"/>
<App_Data App="MOD" Name="Metadata_Spec_Major_Version" Value=""/>
<App_Data App="MOD" Name="Metadata_Spec_Minor_Version" Value=""/>
My XML will have tags similar to above. My requirement is to remove all tags having attribute Value="". How can i achieve this using transformation.
Thanks
Krish

You need to add the xsi:nil="true" attribute to your xsl-construct to be able to ommit the xml-element which are empty.
To be able to do this you need to add a choose-when-otherwise xsl construct inside your mapping file to test for ""-values.
The xsi:nill='true' isn't supported in the transform-activity yet, you need to add this attribute manually inside your xsl-mapping file.
Kind regards,
Nathalie

How to remove xmlns from xml using java

How to remove the namespace using java to get the below xml
Note:I am using XSLT for the transformation.The XSLT tag is not identifying the <DLList> tag with name space

<ForecastName>Devengiri</ForecastName>
<Humidity>89.9</Humidity>
</Weather>
</DLList>
Please help.Let me know if any other information is required
Thanks

OK, here goes :
For the example, I'll use a TB_DISTRICT table with the following structure :
create table tb_district (
sr_no number(3),
district_name varchar2(100)
);loaded with data from this page :
http://india.gov.in/knowindia/districts/andhra1.php?stateid=KA
and this XML document (one additional record compared to the one you posted) :
<DLList xmlns="http://www.test.com/integration/feed" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Weather>
<StateName>Karnataka</StateName>
<ForecastName>Bagalkote</ForecastName>
<Humidity>89.9</Humidity>
</Weather>
<Weather>
<StateName>Karnataka</StateName>
<ForecastName>Devengiri</ForecastName>
<Humidity>89.9</Humidity>
</Weather>
<Weather>
<StateName>Karnataka</StateName>
<ForecastName>Dharwad</ForecastName>
<Humidity>70.1</Humidity>
</Weather>
</DLList>In order to access the XML, I'll also use this Oracle directory object :
create directory test_dir as 'D:\ORACLE\test';Final relational tables are :
create table BUSINESS_TABLE
STATE         VARCHAR2(30),
DISTRICT_NAME VARCHAR2(30),
HUMIDITY      NUMBER
);and
create table REJECT_TABLE
STATE         VARCHAR2(30),
DISTRICT_NAME VARCHAR2(30),
HUMIDITY      NUMBER,
ERROR_MESSAGE VARCHAR2(500)
);With XMLTable function, we can easily break the XML into relational rows and columns ready to use for DML :
SQL> alter session set nls_numeric_characters=". ";
Session altered
SQL>
SQL> SELECT *
2 FROM XMLTable(
3    XMLNamespaces(default 'http://www.test.com/integration/feed'),
4    '/DLList/Weather'
5    passing xmltype(bfilename('TEST_DIR','test.xml'), nls_charset_id('CHAR_CS'))
6    columns
7      state         varchar2(30) path 'StateName'
8    , district_name varchar2(30) path 'ForecastName'
9    , humidity      number       path 'Humidity'
10 )
11 ;
STATE                          DISTRICT_NAME                    HUMIDITY
Karnataka                      Bagalkote                            89.9
Karnataka                      Devengiri                            89.9
Karnataka                      Dharwad                              70.1
Then with a multitable insert, we load both the business table and the reject table (if the district name does not exist in TB_DISTRICT) :
SQL> INSERT FIRST
2    WHEN master_district_name IS NOT NULL
3      THEN INTO business_table (state, district_name, humidity)
4                VALUES (state, district_name, humidity)
5    ELSE INTO reject_table (state, district_name, humidity, error_message)
6              VALUES (state, district_name, humidity, 'Invalid district name')
7 WITH xml_data AS (
8    SELECT *
9    FROM XMLTable(
10      XMLNamespaces(default 'http://www.test.com/integration/feed'),
11      '/DLList/Weather'

22       LEFT OUTER JOIN tb_district t ON t.district_name = x.district_name
23 ;
3 rows inserted

How to remove Unicode from XML file

I get following error when unmarshal xml:
[java] org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x15) was found in the element content of the document.
Anyone know how to remove Unicode from xml file? Can I remove the unicode by rebuild the file?
Thanks

These sort of error usually occur when you're using a different character encoding to read the file than the one you wrote it with. Perhaps if you were to post the problem section of the file and/or the code that created it in the first place.

Emergency!! How to remove elements from a set? or..?

How do I remove elements from a Set?
If I have Set s1and s2, I want to create a new set which consist of all elements in s1 but not in the s2.
Which means, I have to s1.union(s2) and then remove elements of s2.
Is there any method which has this function (remove elment from a set)?
Or is there any other better way to solve this (which doesn't have to remove anything)?
If not, how to design a method which will do this job?
Your help will be very much appreciated.

Hi
you can use method removeAll() from set
s1.removeAll(s2);
so s1 contains all the element not in s2.
If you want to lef s1 unmodifyed you have to create a copy.
Set s3 = s1.clone();
s3.ramoveAll(s2);

Problem in parsing XML using DOM Parser.

Hi,
I am parsing an XML using DOM Parser.
When i try to get attributes of a node, i dont get in the order it is written. For Eg. This the node:
<Level0 label="News" link="/website/ing_news.nsf/ViewNewsForm?OpenForm&All" level="202" uid="COGN-4MNMT3" parentid="aaaa">
When i try to print the attribute values i should get in the order:
News, /website/ing_news.nsf/ViewNewsForm?OpenForm&All, 202, COGN-4MNMT3, aaaa
BUT I AM GETTING IN THE ORDER:
News, 202, /website/ing_news.nsf/ViewNewsForm?OpenForm&All, aaaa, COGN-4MNMT3
Is there any way to sort this problem out?
Thanks and Regards,
Ashok

Hi Guys,
Thanks a lot for your replies.
But i want to keep all the values as attributes only.
the XML file is as shown below:
<Menu>
<Level0 label="News" link="/website/ing_news.nsf/ViewNewsForm?OpenForm&All" level="202" uid="COGN-4MNMT3" parentid="aaaa" children="3">
     <Level1 label="ING News" link="" level="1" uid="COGN-4MNN89" parentid="COGN-4MNMT3" children="3" >
          <Level2 label="All ING News" link="/website/ing_news.nsf/ViewNewsForm?OpenForm&All" level="2" uid="INGD-4MVTK2" parentid="COGN-4MNN89" children="0">
          </Level2>
</Level1>
</Level0>
The code i was using to get attributes is:
String strElementName = new String(node.getNodeName());
     // System.out.println("strElementName:"+node.getNodeName());
NamedNodeMap attrs = node.getAttributes();
if (attrs != null) {
int iLength = attrs.getLength();
for (int i = 0; i < iLength; i++) {
String strAttributes = (String) attrs.item(i).getNodeName();
String strValues = (String) attrs.item(i).getNodeValue();
Also is it not possible to Enforce the order using some Schema/DTD in this case?
TIA

Parsing an XML using DOM parser in Java in Recursive fashion

I need to parse an XML using DOM parser in Java. New tags can be added to the XML in future. Code should be written in such a way that even with new tags added there should not be any code change. I felt that parsing the XML recursively can solve this problem. Can any one please share sample Java code that parses XML recursively. Thanks in Advance.

Actually, if you are planning to use DOM then you will be doing that task after you parse the data. But anyway, have you read any tutorials or books about how to process XML in Java? If not, my suggestion would be to start by doing that. You cannot learn that by fishing on forums. Try this one for example:
http://www.cafeconleche.org/books/xmljava/chapters/index.html

Convertion of flat file to XML using DOM

Hi!
I need help for convert a flat file to XML using DOM and by taking the validation of a specified DTD. Can any body help me in this regard.
Bye,
lat

first you have to decide how the flat file will map to xml. Will you use attributes or pcdata for your fields, or both? Will there be a hierarchy, or will it be mostly flat?
Once decided, you'd probably just use a BufferedReader to read the lines one at a time, and generate Dom nodes as appropriate, and stick them in the tree.

Rounding of decimal values into XML using DOM

I want to roundoff 10.456 to 10.4(while generating the xml) using DOM.
Please let me know how to handle this?
Thanks in advance

read the java.lang.Math API
there are rounding functions there
and next time please just use a search engine

Strange problem with removing element from node

Hi,
I have a problem when I removed elements from a node.
here is the code:
String text = "123456";
IANode nodeA= wdContext.nodeA();
wdContext.nodeB().invalidate();
IBNode nodeB = wdContext.nodeB();
for(int i=0; i<nodeA.size(); i++)
IAElement e = nodeA.getEt_Emp_RespElementAt(i);
if (e.getID().compareTo(text)!= 0)
nodeB.removeElement(e);
else
wdComponentAPI.getMessageManager().reportSuccess(e.getID() + " was not removed");
The node A does have a row with field "ID" equals to 123456.
When running the application, it does write that "123456" was not removed...but it removes it....In fact my table is now empty.
How is it possible if it didn't perform the remove operation for ID = 123456 ?
Thanks in advance.

David,
Because you are iterating node in wrong direction: see my reply to your post Re: Loop problem (seems that you assigns me 2 points without reading reply, and mark it as solved just because you stop solving it
So, in example in this thread, you must iterate node B in reverse direction, get element from B and remove it from B if it has some specific ID.
