XSL and attributes

Using an xsl stylesheet I'm trying to transform this:
<user>
    <streetNo v="123" />
    <streetName v="Main" />
    <streetType v="St." />
    <aptBox v="#4" />
</user>into this:
<user>
    <address>123 Main St. #4</address>
</user>I don't think Muenchian grouping will help me in this case. Will it? There must be an easier way

No, you definitely don't need anything that complicated. Something more simple like<address>
<xsl:value-of select="streetNo/@v"/> <xsl:value-of select="streetName/@v"/>
... </address>should do it, adjusting for whatever is your context node at this point in the stylesheet.

I encountered the same problem. When I change the order of the XML and XSL files, i am the same problem.
Perhaps it's the environment AIX 4.3.3, JDK IBM 1.2.2 with JIT disable (because when JIT is enable some other problems become)??
How can i resolve this bug ?
Thanks.

XSL-TEXT: how to import subtemplates in XSL and use xdofx tags?

Hi,
I am working on a BI Publisher Report (XML Publisher 5.6.3 in EBS) to generate labels on a label printer. The output needs to be in plain text format, therefore I decided to use the XSL-TEXT template and create my own XSL translation.
In principle this works pretty fine, but there are two things that worry me a bit:
1. Does anybody know how I could import other XSL files, like sub-templates in RTF? The problem I have is that I don't know the URI or the sub-template. At the moment I store those other XSL files in the OA_MEDIA folder, but this is not really nice. In RFT you can refer to subtemplates with some xdofx commands... this brings me to my second question:
2. In RTF templates you can use the Oracle specific XML tags, including the <xdofx:%> and <xdoxslt:%> tags. Does anybody know if and how I can use them in XSL templates?
Any ideas are highly appreciated!
regards,
David.

Hi Vetsrini,
1. but what is the absolute path for my subtemplates if I store them in the Template Manager? How can I refer to them?
This is what the manual says for RTFs:
>
Enter the Import Syntax in the Primary Template
Import the subtemplate to the primary template by entering the following syntax in the
primary template. The import syntax tells the XML Publisher engine where to find the
subtemplate RTF in the Template Manager. This syntax may be entered anywhere in the
template prior to the call-template syntax:
<?import:xdo://APPCODE.TEMPLATE_CODE.lang.TERR?>
where
APPCODE is the Application code you assigned to the subtemplate in the Template
Manager. For example, if you associated this template with the Receivables application,
enter "AR".
TEMPLATE_CODE is the template Code you assigned to the subtemplate in the Template
Manager. For example, AR_CommonComponents.
>
sounds good and easy to me. But I don't have a RTF template. I have just a plain XSLT and those XML Publisher tags do not work there. So how do I get the absolute path of my XSLT templates stored in the Template Manager?
2. I've included the namespace, no error anymore. But the syntax does not result in actions:
<xsl:value-of select="xdoxslt:substr((PRODUCT_NAME),1,2)"/>
{code}
This does not substring() my string, the full string is returned. But anyway, I don't get an error message anymore. Maybe I just used the wrong XDOXSLT function... I need to search for a list of XDOXSLT functions, but that's not very urgent for now. I think I can do the most with plain XSL and inside the DB itself.

Creation of Service Product with Set Type and Attribute

Dear All,
Please guide me with proper step by step process,
How to create the product with the set type and attribute for service industry in sap crm 7.0
Regards,

Hi Nitin,
Before creating the Service type of product, you have to define the Base category for Service type product. Generally the category for service will be created under the R3 hierarchy R3PRODSTYPE. You can create this category using the TCode:
COMM_HIERARCHY. Here you have to select the product type as Service and have to assign the set types to the category.
You can create a service product using the transaction : COMMPR01 -> Click on Service ICON -> Select the Category for Service Type. Then fill in the details for Service Product description, Service ID(Based on number range settings for products), Language.
Also fill other details like Base Unit of measure, Pricing condition for different sales areas for the service product.
Since you are using CRM7.0, you can do all these activities using a POWER USER role.
For more information about Set types and hierarchies please refer the following help link:
http://help.sap.com/saphelp_crm70/helpdata/EN/46/57672501a208e7e10000000a114a6b/frameset.htm
Hope this helps!

Difference between text data and attributes in master data?

Hello,
a charcteristic in BW maintains texts, hierarchies and attributes.
What exactly is the difference between texts and attributes?
Attributes describe master data like a customer. The country where the customer resides, the industry etc. describe and classify the customer. Attributes are not just the structure/metadata of the characteristics. They are also the content. The following table should visualize what i mean:
customer-no. | name
112 | mcpherson inc.
113 | donalds inc.
Texts contain contain the description of a characteristic. Texts define a characteristic. An example is the customers name. It does not describe the customer but defines him/her.
Is my understanding about these two parts of master data right?
What else except the customer's name belongs to the texts?
If I set up a characteristic like the customer in SAP BW, do I have to create an attribute "name". The name belongs to texts, not to attributes?? If I upload master data then, how does it work?
Thanks in advance.

Hi,
If your analysis includes country and region then country and region should be included in the Infocube.This is required because only if you include these characteristics then you can restrict your queries for country and region.You may need to select some particular countires/region and show the report.Then you have to restrict your queries to only those countries/region.This is possible only if you have these characteristic in your infocube.
I am just envisaging your model like this.
Characteristic in the Infocube
Customer
Country
Region
Customer Attributes
Customer Number (SID which is self generated)
Customer Address1,2 ,3
Registration No
Date of Registration
Deposit Amount
etc ...
Region Attributes
Region Number (SID)
Total Customers
Sale Office Address
Number of Sales Persons
Customer Attributes
Customer Number (SID)
Total Customers
Head Office Address
Number of Sales Persons
GDP
Total Population
So the conclusion is whichever entity you want to restrict or analyse should be a part of Infocube.It is very difficult to do analysis based on attributes as I mentioned in my earlier post that they are only "Display attributes" (u can just show that's it).
Yes!! there are methods available for analysis based on characteristics in attributes table and you have to do either with virtual characteristic or replacement path or with writing code in customer exits.But a good design and earlier study of all possible report combination and having a good design will avoid good amount of development time and changes.
I have suffered when I had only 0CALDAY in my cube and when I want to take a monthly analysis, I was unable to do it and then I have to redesign my whole cube.
Please anyone, correct me if I am wrong.

Parsing DOM with XSL and output as HTML

In a servlet I am fetching data from DB into an DOM-tree (using ordinary JDBC and building the XML-DOM while fetching rows). This is done in a servlet, and before I response to the browser i use Oracle XML-parser to join my DOM-tree with an XSL-file. If I try to my DOM-tree out before parsing, it contains data. But the parsed DOM only contains XSL-tags, no data. What do I do wrong?
Here is the code:
DOMParser parser = new DOMParser();
parser.setPreserveWhitespace(true);
//No problem finding the XSL-file...
URL xslURL = createURL("employee.xsl");
parser.parse(xslURL);
xslDoc = parser.getDocument();
XSLStylesheet xsl = new XSLStylesheet(xslDoc, xslURL);
XSLProcessor processor = new XSLProcessor();
processor.showWarnings(true);
processor.setErrorStream(System.out);
//XML doc does contain data!!!
DocumentFragment result =
processor.processXSL(xsl, xmlDoc);
xmlOut = new XMLDocument();
Element root = xmlOut.createElement("root");
xmlOut.appendChild(root);
root.appendChild(result);
xmlOut.print(out); // Result is only the XSL-file.....
Regards Frank =:>

Sorry, but I still can not make it work. Here are the XSL and XML-files. My XML test file (which reflects the DOM I am makings
is:

Function and attribute tabs not visible in ppoma_crm

Hello Experts,
Function and Attribute tab at the sales organization level is not visible in PPOMA_CRM transaction code for one of the user.
Is it due to some authorization issue ? or anything else ?
Before taking a system trace for that specific user, I would like to know if we are missing anything functionally
Kindly revert
Thanks and Regards
DJ

Hi DJ,
Please see note 926540 - Missing Organisational units
But from your description this does not seems to be the exact symptom.
Yes I would advise to run a SU53 authorization check.

XSL and Schema

I'm using CS3 to create a series of XSL files to transform XML but when i'm in DW, in the bindings tab, when I create a fragment XSL and point it to attach to a remote source I get
'unable to locate or parse the xml source'
I'm sure my source is correct
Thanks

Maybe it is, but without seeing the XML source you're trying to load, it's impossible for anyone to help.
A quick way to verify that an XML document is correctly formed is to load it into the latest version of any browser except Internet Explorer. If the XML is correctly formed, the browser will display the document tree. If not, it will display an error message.

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.

CF10 CFML tag, functions and attributes autofill in Dreamweaver CS5.5

We have Coldfusion 10 and Dreamweaver CS5.5 in my company. We want to be able to see all the CF10 CFML functions, tags and attributes in the autofill when writing code. I have found an Adobe link to a download for them but it doesn't say what version of Dreamweaver is required for it to work. Can someone please tell me? Will it work with CS5.5?
(This window won't let me paste in the link I have but it's in the Coldfusion Support Center Downloads | Coldfusion 10 Devleoper Tools | Adobe Coldfusion 10 Extensions for Dreamweaver. Also note that we do have CS5.5 in my company but I don't have an install available for me to test so I'm hoping it will be easier to get an answer to this question here rather than obtain one....thanks)

This is what you are looking for : http://help.adobe.com/en_US/ColdFusion/10.0/Installing/WSc3ff6d0ea77859461172e0811cdec1896 9-7fff.html
Download MXP from here : http://www.adobe.com/support/coldfusion/downloads.html#cf10devtools
Insatll and then launch Dreamweaver CS 5.5

Hiding methods and attributes while inheriting

Hello All,
This is kinda urgent. While making a subclass I want to block access to methods and attributes of super class when anone creates an object of sub-class. In my particular situation I cannot override the methods.
Let me explain it with an example:
I have a class A which contains an attribute of type Object. All the methods accept Object type parameters and act accordingly. Now I want to create a sub-class B which acts on Strings only. I can create a wrapper to class A but I want to add some behavior which is specific to strings and use rest of the behavior as in class A. I cannot override the methods of class A because they take Objects as parameters whereas in class B the same methods take string as parameters.
I hope you have understood the problem. Please reply ASAP.
Thanks in advance

Sorry the diagram turned out wrong. ObjectClass and StringClass are both supposed to be derived
from the AbstractBaseClass.
This method is one way to achieve what you want. You make an AbstractBaseList class that has only
protected methods that take objects.
To implement a generic Object version of this class you extend it and override the protected methods in
the AbstractBaseList class to make them public.
To implement a String list you extend the AbstractBaseList class and override the protected methods to
make them public (but change the type of the parameters).
The only problem with this approach is that the return types of the methods cannot be changed. Therefore
I recommend the AbstractBaseList implement a method called
protected Object getByIndex(int i) {
// do list type stuff in here
Then the ObjectList can implement
public Object get(int i) {
return super.getByIndex(i);
and the StringList can implement
public String get(int i) {
return (String) super.getByIndex(i);
In effect all you need to do is to implement wrapper classes that enforce type casting on the Object based
set/get values.
Another option is to use JDK1.5 with its generics classes. These effectivly allow you to specify which type of
object an instance of a class accepts.
Another question. What is the matter with the Collections classes provided in the JDK?
