How to search for a particular element within a XML variable using studio?

All,
I am using studio 7.0 to develop a webbased application. In this, i need to access
an oracle db using a WLAI Application View from my Workflow. I get some data back
from Oracle as an XML variable and then apply an XPath statement to access the
individual columns returned.
My problem arises when there are no records in the db matching my criteria and
an empty XML variable is returned to me from the app view. In these cases my
XPath statement fails in studio causing an improper exit.
Does anybody know how to check for content in a XML varaible using studio? So
that if there is content i can proceed with XPath and if there is no content,
then i will take a different route.
Thanks in advance
Regards
Sri

If I remember correctly, the adapter will return an XML document that contains
XML elements for each row. You can just simply check the count of these elements
with an XPath statement: ie. count(response/row)

How to search for a particular pattern in a string

Hi,

Hi ,
How to search for a particular pattern in a string?
I heard about java.util.regex; and used it in my jsp program.
Program I used:
<% page import="java.util.regex"%>
<% boolean b=Pattern.matches("hello world","hello");
out.println(b);%>
I run this program using netbeans and am getting the following error message.
"Cannot find the symbol : class regex"
"Cannot find the symbol : variable Pattern "
How to correct the error?

How to Search for a specific element in a MultiGraph?

Hi there
Im trying to implement a Multigraph ADT in Java. Multigraph is a graph that has multible edges connecting a node. I assume you all know what a Graph ADT looks like.
So i think ive got all the basic methods functions of a normal graph/mulitgraph and now i want to search for a element in it
The question is how will i so that?
Do i use a breadth first search?
But i thought a BFS traverses all the elements in a graph? And how can i use a BFS to search for a specific element in a graph?
Thanks

Hey there
thanks for your reply but i still some query.
I thought of doing that but i want to remember the nodes i revisted to get to the target (not all - but the quickest route to that node)
My design so far is:
have 3 Interface namely Graph, Node & Edge.
Classes will inherit those interface to provide the actual implementation as i want the details/coding to be abstract meaning i can give many different way of implementations.
The graph class will add nodes & edges where when adding edges, edge will store 2 nodes in it respectively source & destination nodes.
Both Node & Edges will be stored in graph using some data structures atm (arrayList i presume)
My Design is that i want to (my aim of the task of searching) search for a node in the multigraph by inputting (maybe 2 nodes) into method - start node target node! The method should return a list of nodes to get to the target node.+
So so far i have this wee algorithm in mind:
+1. Input start + target node as parameters+
+2. Use BFS to search the graph+
+3. When reached target node - halt+
+4. return the list of nodes that visited to get there (but not all - only the precise & fastest)+
So will that work?
If so how do i go about doing implementation?
Thanks

How to search for the particular ABAP Object

Hi,
I am using the SAP 4.6C machine, I need to search for the particular ABAP Object. Plz can anyone help me in this.
Regards,
Pralhad P. Teggi

You'll get a better response if you ask a meaningful question.
If you want to scan for Business Objects (BOR) use transaction SWO1
For ABAP classes / objects use a combination of transactions SE24 / SE18 / SE19 and /or SE80
(SE 18 / SE 19 are for Badi's)

How to search for a specific String within an ArrayList

I am creating an inherited class, CD, that has a field of "tracks". I am wondering how you would search through the ArrayList and list the track number that correlates with a search term. For instance, if I have a track called "Radar Love" and it is track number 2, how would I create the search function to find out what track number "Radar Love" is?

trojansc82 wrote:
int index = 0;
boolean found = false;
while(index < tracks.size() && !found){
String track = tracks.get(index);
if(track.contains(searchString)){
found =true;
else{
index++;
return index;It's still the same code. I attempted putting in a return statement with tracks.get(index), but it didn't work.Edited by: Edward_Kimber on Nov 15, 2008 2:57 PM

How do I search for a particular email message, or set of email messages, by sender, topics, etc. on the iphone?

When searching for email messages from within Mail or when using Spotlight, you can search the To, From, and Subject fields. Search "All" searches all three of these fields. The text, or body, of messages is not searched.

Problem in digitally signing a particular element of an XML Document

hi all!!
I was trying to sign a particular element of an XML document using JSR105 (XML Digital Signatures) API.
For which i used +#xpointer(id('idvalue'))+ and +#idvalue+ as the URI for the reference i create as below :
Reference ref = fac.newReference("#xpointer(id('123')) ", fac.newDigestMethod(DigestMethod.SHA1, null), Collections.singletonList(fac.newTransform(Transform.ENVELOPED,(TransformParameterSpec) null)), null, null);
NOTE: Here 123 is the value of the attribute 'id' of the element i wish to sign in the input XML document.
But when i try to digest and sign the the above created reference, i get the following exception (which is strange! atleast for me!)
Exception in thread "main" javax.xml.crypto.dsig.XMLSignatureException: javax.xml.crypto.URIReferenceException: Can't resolve ID: '123' in ''

My output is ns1:abcd .. i want only "abcd"...
The parser is returning the correct rootNodeName i.e ns1:abcd. rootNodeName always goes with the given input and returns the root element as is.

I guess.. I need some namespace evaluation to be set..

When I do a search for a particular song in the iTunes store, how can I change the view for the results?

I have the latest version of iTunes. Today I did a search for a particular song. In the past, I used to get a list of the song and the various artists who recorded it, and I could click the little arrow and play a preview of that song before I decided to buy it. Today the results didn't display that way - instead, I got a page with probably 50 or 100 songs all spread out across the page, and the "writing" was all overlayed so you couldn't quite tell what you're supposed to see! I want to go back to the "list" view but couldn't find anywhere to change the view preference. Any idea how?
