How to start learning XPATH and XQUERY

Hello
Please I am needing some guide to know if there is a guide that I could follow so that I can handle from the very beginning till the end an XML Document.
Besides I need to know if with JDeveloper I can edit and update an XML document (data type XMLTYPE column) inside of a table.
I'll appreciate your help.
Paola.
@}--->----->>----------

You could have a start here http://www.w3schools.com/. also the old XMLDB manuals 9.2, 10.1 had primers on handling xml (appendix section), another source for you could be the w3c organization: http://www.w3.org/.
AFAIK, JDeveloper doesn't have that functionality yet. AFAIK the latest toad version is able to do this...

XSLT and XQuery recommendation for BPEL and OSB

Hi,
1. Why is XQuery recommeded for OSB and XSLT for BPEL. Are there any specific performance optimization reason behind this.
2. Apart from OSB and BPEL, both XSLT and XQuery has xml transformation options and creating HTML. What is the difference between these two.
Thanks in advance!

you can create the graphical view of Xquery in Eclipse but not for XSLT
Xquery is much faster than XSLT in OSB.
Through XSLT however you can achieve more complex transformation.
OSB has its historic origins in BEA Aqalogic stable and so Xquery was widely used used even though XSLT is supported. It is a matter of choice(your standards in your organization,your developer skillsets,your re-usable libraries etc )
In Jdeveloper you can develop xslt in graphical mode though and attain complex transformation

XPATH and the C parser

Can I use an 'XPATH' expression to find a node using the C parser?
eg find '/A/B/C'
The Oracle Java parser supports this.
Thanks for your help.
Doug

Yes, we have Xpath and XSLT support in the parser.

XSLT Mapping and Graphical Message Mapping

Hi,
Can any one let me which is advatageous and why or let me know where I can find docs.
Thanks In Advance.

Hi Udo,
I have used a lot of XSLt outside and from my own experience(java/c#) we have been hit very hard with performance when using XSLT, it is an interpreted approach.
It may look easy, fast but in time you will pay the price. Java and ABAP mappings are compiled, and only the runtime is maintained.
Is XSLT useful, sure it is, there are many things that can be done in XSLT that is very tough to accomplish using mappings.
Should it be the first choice of development, no its a case by case basis.
Most common disadvantages of XSLT are
-Scripts rapidly explode in size
-Quite complex
-Hard to debug
-Slow processing
There is an ever ending debate on pros and cons of XSLT. It upto individual Architect to decide whatz best for the interface at hand.
cheers,

Source of xslt mapping and XSD/ XMT target structures for standard Idocs

Hi,
I am working on R/3 - XI - ICH scenario. I need xslt mapping and XSD/ XML target structures for standard IDoc like PROACT01,DELFOR01, DELVRY03. I tried to search it on marketplace but couldn't find it there. As per configuration document, these things are shipped with XI mapping content in live cache CD. But I don't have this CD with me. Can anybody tell me the source for these target structures and mapping program. ( Please share marketplace, site link or send me across the mail [email protected])
Thank you in advance.
Anand More.

Anand the other option is to import the corresponding idocs into your integration repository and then you can view the generated XSD there.
As regards XSLT mapping, you need to basically first identify as to what form you want to transform your source idoc into.
For some help on XSLT mapping check the following threads,

XSLT Mapping and Namespace Issues

I have been reading through similar threads on this topic, but have not found the right combination for my problem. I am doing an XSLT map and it works fine in Stylus Studio. When I take it to PI, I get a "Prefix 'ns0' is not mapped to a namespace" error. I have a namespace that is within the XSD files I received from my partner (http://www.ups.com/XMLSchema/EBR/Billing/v1). I also have the namespace I made in PI for the source (http://graybar.com/upsbilling/) and a different namespace in PI for the destination (http://graybar.com/cold/invoice/).
<u><b>XSLT:</b></u>
<?xml version='1.0' encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns0="http://www.ups.com/XMLSchema/EBR/Billing/v1" xmlns:ns1="http://graybar.com/cold/invoice/">
<xsl:template match="/">
<ns1:ColdInvoiceData>
<Header>
<RecordID>HDR</RecordID>
<InvoiceDate>
<xsl:value-of select="ns0:UPS_EBR_BILL/ns0:InvoiceDetails/ns0:Invoice/ns0:InvoiceDateCCYYMMDD"/>
</InvoiceDate>
<u><b>Source XML</b></u>
<?xml version="1.0" encoding="ISO-8859-1" ?>
<UPS_EBR_BILL xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.ups.com/XMLSchema/EBR/Billing/v1" xsi:schemaLocation="http://www.ups.com/XMLSchema/EBR/Billing/v1 Billing_XML_Schema.xsd">
<XMLBillFileVersion>1.0.1</XMLBillFileVersion>
<Recipient>
When I change the XSLT namespace from http://www.ups.com/XMLSchema/EBR/Billing/v1 to http://graybar.com/upsbilling/, the TransfromerException in PI goes away, but none of my referenced mappings work either (just my text hardcodes).
Can someone tell me why this works in Stylus Studio, but not in PI? Do I have too many namespaces?

> <ns1:ColdInvoiceData xmlns:ns1="http://graybar.com/cold/invoice/">
This change did not affect anything. Still works in Stylus Studio though.
Did you mean to show any changes at the <xsl:value-of select> line? I did not notice anything there.
Can anyone explain what "not mapped to a namespace" means? I have the declaration of ns0 at the top, so I don't see what else needs to be mapped. Do I have to have my PI namespace where I store the partner's XSDs set as "http://www.ups.com/XMLSchema..." (partner's namespace)?

AquaLogic Service Bus and XQuery Mapper

Hi all,
I'm new about using AquaLogic Service Bus and XQuery Mapper. I'm using alsb250_wls920.
To understand better the details I've developed two very simple EJBs stateless related to a generic CarRental scenario.
The idea is the following:
- EJB1 exposes a method for retrieving available cars from company A
- EJB2 exposes a method for retrieving available cars from company B
The method signature is the same:
public CarVO[] getAvailableCars(Category category, Double price)
the only difference is about the CarVO definition where one exposes more attributes than the second one (and also the package is different).
The goal is designing a new proxy service called getAvailableCars that calls the two above services and returns a set including all available cars from both companies.
The returned CarVO is the sum of all attributes from two above CarVOs plus a string company attribute.
So in AquaLogic I've defined:
- a JAR resource for importing my CarRental.jar
- two BusinessService resources related to the two above getAvailableCars services (from company A & B), called getAVISAvailableCars & getHertzAvailableCars;
- I've exported the two WSDLs from the two above BusinessService resources directly from AquaLogic console;
- I've written manually the WSDL 'getAvailableCars' that I use in the next proxy service definition
- a getAvailableCars_1 proxy service resource
Before completing the proxy service definition, I've decided to use XQuery Mapper for defining my trasformations.
But I got some errors when I try to import the WSDLs.
For importing simply I've created a wsdl folder inside my project and copied into it the 3 WSDLs definitions.
Because there are errors in 2 of these WSDLs (getHertzAvailableCars.wsdl, getAvisAvailableCars.wsdl) when I create a XQuery Transformation, I'm not able to select any source schema.
But getHertzAvailableCars.wsdl, getAvisAvailableCars.wsdl have been generated directly from AquaLogic console and I don't understand why XQuery Mapper complains about them.
If needed I can post also the CarRental.zip eclipse prj (that contains the above two EJBs) and CarRentalAqualogicPrj.jar AquaLogic prj (passphrase is aqualogic).
I thank you in advance for any suggestion.
Regards
Patrizio

XPath and ERMS

Hi gurus,
We're creating our own Services for ERMS (CRM 6.0) and I was after a spot of advice.
Can anyone give me some guidance as to where to find all the XPATH entries available?
In the ERMS Repository there are attributes defined with XPATH entries against them, but I'm sure there must be other XPATH entries available, and if we wanted to define our own attributes I was wondering where I could look to find this XPATH information?
Thanks in advance,
Andrew G.

Hi !
WSDL, XSD, Xpath and BPEL are all open standard.
ABAP for instance, is not an open standard.

XPath and oracle parser

Hi,
I am using Oracle parser to parse my XML file, as i found that it is faster then IBM and sun parser, But i think it does not support XPath, so how can i use XPath and oracle parser, I can also use Sun parser , but dont know if it has XPath support,
So please help me out

I suppose it supports DOM or a saxHandler that can provides you a DOM
tree. For Xpath, may I suggest you my solution : http://www.japisoft.com/jxpath

Does the XMLP full or partially support the Xpath and XSLFO syntax?

Does the XMLP full support the Xpath and FO syntax? or partially? Thanks

Hi Robin
OK, so hopefully you are not leading me into a trap here :o)
There are two parts to this question:
1. XPATH - we support as much of the XPATH spec as the Oracle XDK supports ie we rely on the XDK for our transformation engine so as long as they support what you are trying to do then we do. There are a few gaps and we have plugged those in the XMLP layer. So the short answer is yes.
2. XSLFO - we allow you to use XSLFO in your template. The XMLP engine supports much of the standard but there are a few gaps. the next set of docs will layout exactly what we do support in the spec.
