Xml, xsl and database

I have several xml documents that uses different tags to describe the same type of information. In my case they describe a row in a database table.
file1.xml
<therow>
<name>Jones</name>
<title>manager</title>
</therow>
file2.xml
<arow>
<employee>King</employee>
<job>manager</job>
</arow>
I want to use a technology for reading the content of the two files and generate a new document for each file that will use generic tags so the content of the new files could look like:
file1
<row>
<employeename>Jones</employeename>
<employeetitle>manager</employeetitle>
</row>
file2
<row>
<employeename>King</employeename>
<emplyeetitle>manager</employeetitle>
</row>
An then I can read this information by using a generic Java class and insert it into the database table..
I was told that the technology used for doing this was XSLT. I have been searching the web for examples and also tried to read some of the content in the Steve Muench book 'Building Oracle XML Applications'.
I have managed to create XSL files, but I would really appreciate if someone could show me a real example of how to do this, with the xml file, the xsl file, and a small java program to read this. Can anyone help?

XML, XSL, and why I need a URL to create a XSLStylesheet

In order to convert XML>>HTML I need to specify both the XML (data) and the XSL (stylesheet). Great.
Before I slap these two together, I need to create an instance of XSLStylesheet, which takes my raw XSL file and a **URL**?
XSLStylesheet xsl = new XSLStylesheet(xsldoc, xslURL)
What is this URL used for? Antoher XML processor I'm migrating from does not require this, and it looks like I can't avoid it. (There's no constructor for the XSLStylesheet that DOESN'T need the URL.)
QUESTIONS:
- Is there a way to avoid specifying a URL?
- If there's not a way, can someone tell me what the URL is being used for? All I see from the Javadoc is that it's a "Reference URL for include, import and external entities". Would love to be able to expand on that - leaves me in a fog.
Thanks!
Will.

try using "null" as argument for url

Xml, xsl and jsp

I used this code to create an xml file through an xsl:
<%@page import="javax.xml.transform.*,javax.xml.transform.stream.*,java.io.File,java.util.Properties" %>
<%
File fXml = new File("C:\\file.xml");
File fXsl = new File("C:\\file.xsl");
File fRes = new File("C:\\res.xml");
StreamSource xml = new StreamSource(fXml);
StreamSource xsl = new StreamSource(fXsl);
StreamResult res = new StreamResult(fRes);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(xsl);
transformer.transform(xml,res);
%>
but in the res.xml file i have:
<table> instead of <table>
what can i do to solve this problem?
thanks

I'm near to solution
i use
StringWriter resultStringWriter = new StringWriter();
StreamResult res = new StreamResult(resultStringWriter);
and then
transformer.transform(xml,res);
String str = resultStringWriter.toString();
this is my xsl:
<xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" indent="yes" encoding="ISO-8859-1"/>
<xsl:template match="XMLDATA">
<![CDATA[<tag1>]]><xsl:value-of select="CodiceAmministrazione"/><![CDATA[</tag1>]]>
</xsl:template>
</xsl:stylesheet>
but now the problem is the output:
\r\n<tag1>Test</tag1>\r\n
and not
<tag1>Test</tag1>
If I write the xsl on one line i have no problem
Can you help me please?

I am trying to generate a PDF from XML, XSL and FO in java. It works fine if the PDF to be generated is small.
But if the PDF to be generated is big, then it throws "Out of Memory" error. Can some one please give me some pointers about the possible reasons for this errors. Thanks for your help.

Getting data from an XML file and pushing it to a database

I need to create a coldfusion page that grabs an incoming xml file, extract the data and then push it into a database. I have never done anything like this, and have been reading as much as I can find. Can anyone recomend a good resource or give me a hand on how I go about doing this?
The xml file is coming from another page. Basically the source page is a simple text box that an xml file is pasted into and submited. The action page must grab the xml file, pull out the data and funnel it into a table. Then it must query the table and based on the results of the query, push a new xml file back to the user.
<my brain is already hurting>

I'd start by looking at the CF documentation related to XML and Ben Forta's books.
"About XML and ColdFusion" from CF docs:
http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec133ba -8000.html
Ben Forta's books
http://www.forta.com/books/0321679199/
It would be good to know:
1. What the workflow is for your task. Can you describe your task in detail and provide samples of the XML and database?
2. The database you are using and the structure of your tables.
3. The version of CF you are using.

Convert flat file to XML document and store into Oracle database

First:
I have a flatfile and created external table to read that file in Oracle
Now I want to create an XML document for each row and insert into Oracle database, I think that XMLtype.
Could you please provide me some information/steps.
Second:
Is there performance issues, because everyday I need to check that XML document stored in the database against the in coming file.
Thank You.

Oracle 11g R2 Sun Solaris
Flat file is | (pipe delimited), so I did create an EXTERNAL Table
row1     a|1|2|3|4
row2     b|2|3|4|5
row3     c|6|7|8|9
I want to store each record as XML document. So it will be easy to compare with next day's load and make insert or update.
The reason is:
     First day the file comes with 5 columns
     after some days, the file may carry on some additional columns more than 5
     In this case I do not want to alter table to capture those values, if I use XML than I can capture any number of columns, CORRECT!. Please make me correct If I am wrong.
     This is the only reason to try to use the XMLType (XML Document)
     On Everyday load we will be matching these XML documents and update it if there is any column's value changes
daily average load will be 10 millions and initial setup will be 60-80 millions
     Do I have anyother option to capture the new values without altering the table.
Please advise!.

Using resourceDescription in SUBSCRIPTIONBUNDLED_Email.xsl and xml's.

Hello all,
We are trying to use the Primitive Template "resourceDescription" (as described in "Customizing Notifications"-pdf) in the SUBSCRIPTIONBUNDLED_EMAIL.xsl and SUBSCRIPTIONBUNDLED_en.xml.
Could anyone urgently let me know if it's possible to use this Primitive Template in the xsl and xml mentioned?
It looks like the "resourceDescription" is not being passed on to the bundlednotificationdata-section in the xml?
Any other suggestion in how to get the "resourceDescription" available in Daily Summary Subscription emails?
Thanks in advance,
Tim.

Hello Alan,
Yes; as far as I know the only way to get your changes to any of the email notification xml files visible is by restarting the server
The notification email xsl I'm working on is the one for the daily notifications (subscriptionbundled_email.xsl).
My problem is that it seems that the resourceDescription is not being passed on by the java code that is populating the section in the xml file containg the resource information...
Unfortunately no confirmation about this yet (raised OSS with SAP as well).
I'm expecting this resourceDescription to contain the text that you can fill in using standard KM in the Description field of a resource.
I do wonder how/where your users populate the subject and description fields? Standard SAP KM or custom app?
Cheers,
Tim.

Weaknesses I've come across in the Oracle XML/XSL implementation

Weaknesses I've come across in the Oracle XML/XSL implementation
NOTE: I think Oracle is a fantastic database and the XML implementation is lovely to use - also I know these are not limited to XE and also that some are fixed in 11g enterprise however I'm not sure if all are so I am posting here in the hope that Oracle will include fixes for all if any have been missed
1. getclobval() returns a spurious carriage return on end of the value returned
2. extract does not handle mixed content tags well (for example it simply discards tags that only have whitespace between them
3. XSL: using a xsl:number level="multiple" with anything beyond a simple count= xpath value crashes the database completely
4. XSL: insists on pretty printing output XML which is extremely odd behaviour and causes problems when dealing with mixed content

Another weakness I've seen is with the appendchildxml function and mixed content xml - it appears to likewise pretty print XML causing the injection of carriage returns and whitespace into mixed content nodes

XSL and classpath

I have an class deployed to the database (8.1.7) that is performing a XML query and then using processXSL to transform XML query result into standard form. I know this might not be standard but it solves some issues pretty neatly. My problem is that in the XSL file (also deployed to the database) I have some java extensions. The XSL processor is reporting a class not found exception for this extension class. Now I have deployed the jar file of my java extension utilities (to the same schema as my other classes), I thought this would be sufficient. I have tested calling the static member methods of my extension class directly before applying the ProcessXSL statement and this works fine - this tells me that the class can be can be found.
Any suggestion would be appreciated.
null

You have to make sure that you load the class into the same schema as the user who is executing the stylesheet. If the class belongs to any package like "a.b.c.ClassName", then you must make sure the class is JAR'd up with the correct subdirectory structure mimicking the package structure:
So, if you to a jar tvf on your JAR file (before loadjava'ing it) you should see the class in the JAR file as:
a/b/c/ClassName
and not just
ClassName

About XML/XSL:Urgent

Hai ,
I am developing one module which invloves XML database ,XSL and Javascript. In this I want to transform XML data to XHTML form using XSLT ., I have done this ,(using xsl templates ,In my form two radio buttons one dropdown box and two text boxes are there .). All the information which ever is displayed coming from XML ., ----- But I want to validate this elements (which are in xslt ,ie checking text box is empty or not ..) Where I have to add script in XSL ., Plz give simple example on this[/b
Thank You .,

And what does that have to do with XML Publisher?

XML, XSL, XSLT, DOM?? What should be used?

I want to develop an application using JSP, Java, mySQL, and XML.
The application needs to be able to store data in the database but also define this data using XML. Some sort of style sheet for this data is also needed to assist in creating forms based on this data and style sheet on the fly for a new page that needs to be displayed based on the data that was entered before.
What XML technolgoies could best help in this situation? Can you see any problems associated with building these pages on the fly based on the XML and XML style sheet???
Any feedback or suggestions would be greatly appreciated?
Thank you and I look forward to hearing from anyone that could help!!!!

Two things. One JRUN has a JSP tag that converts XML and an XSL to XHTML. Despite the preference of some (who must work with only XML enabled browsers) many people on the internet and even some corporate intranets do not have XML enabled browsers thus the XML/XSL solution does not present usable data to them.
The conversion to XHTML makes this data presented to ALL browsers.
A good reason for having the XML is that this has become the defacto standard for communication between businesses/applications on the web. Especially with any Web Service usage XML will almost certainly be required. In other words, minimize rework use a "standard" data that is usable my many different layers of presentation.
Hopefully I was clear enough. I am using XML as a pre-presentation data format and then using various forms (including JAXB) to present the data or manipulate the data depending on requirements.

Good Books for XML/XSL
