XML count nodes?

Hi everyone,
I'm developing part of a website that will open up an XML /
RSS file (downloaded nightly from another site), extract article
text and href link, then dump that info into an HTML DIV.
The problem I've having is that I've only been able to get it
to work by hard setting a number of articles (nodes) to process.
In the attached code, you can see that I've set it number of
items at 10 [see: <cfset numItems = 10>]. Of course when
there are more then 10 articles, I'm only seeing 10, and when
there's less then 10, the whole script blows up.
Is there a good way to dynmaicly set the #numItems# variable
by coutning the nodes under "mydoc.feed.entry.content" in the XML
file?
Thanks in advance,
- Ian in Los Angeles

I think you can use ArrayLen().
Check out this page, it really details all that you can do in
Coldfusion as far as manipulating XML objects:

Specifically, change your numItems line to:

Count nodes function used by me is :
ora:countNodes('receive_InventoryReconcilliation_receive_InputVariable','body','/ns2:Root/ns2:Batch/ns2:OnHand/ns2:ItemCode')
or
ora:countNodes('receive_InventoryReconcilliation_receive_InputVariable','body','/ns2:Root/ns2:Batch/ns2:OnHand/ns2:ItemCode')
I have tried using countNodes in above two ways.
Inspite of that i always get count of nodes as 0.
How should i resolve this issue ?
Thanks in advance,

Hi Sasmit...
i was facing a same problem recently...i can see the B2B adaptor giving the file as input to my BPEL process but the count is coming as zero...then what i did was..i tried copying the value of an element in the input variable...i cannot copy the value too...So, then i figured out that when i defined the document definition in B2B console, we will be giving the XSD file right...that schema file is not in sink with the file being picked up...may be i might have done amistake while generating the XSD file for a particular document in B2B Editor...then later i created the document definition i mean the xsd file in B2B Editor and used that new XSD file in my document definition...then i could access all the data in my BPEL process...
Just try this..,may be it helps.
Thanks,

Tree control with xml last node!

The question is how to view the tree lastleaf as last
nodename + nodevalue in an xmlobject?
<node1>
<node1a>10
</node1a>
</node1>
<node2>
<node2a>
<node2b>20
</node2b>
</node2a>
</node2>
I want the tree structure like:
Node1 (folder icon)
Node1a = 10 (doc icon)
Node2
Node2a
Node2b = 20 (doc icon)
In Flex the tree views:
Node1 (folder icon)
Node1a (folder icon)
10 (doc icon)
Node2
Node2a
Node2b (folder icon)
20 (doc icon)
in my app I get a result from a webservice that returns some
nodes that can have one or more values. Say Node1a can have 10, 34,
43, so in the tree leaf I it should view Node1a = 10, 34, 43.
Any suggestions?

The problem is when the value is between xml tags (
<node>value</node>) the node name gets folder icon and
value gets doc. icon.
With lot of last elements, one has to click every node to see
the values.
With labelFunction every leaf gets null value:
If hasComplex return localname
Else
Return localname + children
When I try to pars xml to new one, hasChildren returns true
for las element, and if there is no value the node shows null.
Then walking the xml recursively how do I insert the nodes in
new xml with the same structure but tags like (<node
data=”value” />)? (to XMLListCollection)
Hope it’s clearer

How to count nodes?

I'm new to DOM and am trying to understand the node hierarchy structure. I have the following sample XML file.
To understand what constitutes a "Node", I count and print the child nodes that are within the "slideshow" node. The result I get is that there are 5 nodes and the node names are: #Text, slide, #Text, slide, #Text
Can anyone explain to me how--based on the xml file below, there are 5 nodes within the slideshow element?

<slideshow title="Sample Slide Show" date="Date of publication" author="Yours Truly">
     <slide type="all">
          <title>Wake up to WonderWidgets!</title>
     </slide>
     <slide type="all">
          <title>Overview</title>
          <item>Why
               <em>WonderWidgets</em>
               are great</item>
          <item/>
          <item>Who <em>buys</em> WonderWidgets</item>

Grabbing the elements from the XML root node

Hello, I haven't worked with XML in over a year and I didn't use it much then. I'm trying to remember the best way to get the values from the root note (not child nodes).
For instance, in the following xml, I want the timestamp and the messageID from stumessages.
I can't recall if you are supposed to use xmlsearch or something else. I know how to grab the child nodes (for some reason, that part was easier to recall).

Hello,
I figured it out.
I figured I would update my post in case anyone else was curious.
I just need to add the following two lines into the code to expose the elements of the root node.
    <cfset timeStamp = MyXMLDoc.stuMessages.XmlAttributes.timeStamp>
    <cfset messageid = MyXMLDoc.stuMessages.XmlAttributes.messageID>
The full code follows

<cfset MyXMLDoc = xmlParse(XMLFile) />

Retrieving a xml element/node as clob

New at this - so forgive the basic frustration here...
I have successfully loaded an XML file to be stored as Binary XML table in Oracle 11g. The XML file represents and describes data for use on websites, hence there is a vary large node representing the body text of an HTML page.
I have not attempted loading this XML file with an internal DTD or external xsd at this time, trying to keep things simple for now.
The following query results in an error
SELECT extractValue(value(c),'/article/article_body_page_html') article_body_page_html
FROM WEBSITE_CONTENT2 a,
TABLE(XMLSequence(Extract(object_value,'/website_content2'))) b,
TABLE(XMLSequence(Extract(value(b),'/website_content2/articles/article'))) c
WHERE extractValue(value(c),'/article/article_id') = '61041';
ERROR String result too large
I have tried XMLCAST(extractValue(value(c),'/article/article_body_page_html') AS CLOB) to no avail
It would seem I cannot be the first person running into this issue - and not being a PL/SQL or XML guru - I need some specific examples of retrieving a node/element where the data represented is:
1. Variable in length
2. Exists in the xml file as cdata
3. probably well over 4000 characters.
Could someone please help to provide a solution to what seems a very basic issue.
Thanks in advance.

From the 11.1 documentation on ExtractValue it has
"For documents based on XML schemas, if Oracle can infer the type of the return value, then a scalar value of the appropriate type is returned. Otherwise, the result is of type VARCHAR2. For documents that are not based on XML schemas, the return type is always VARCHAR2."
You should be able to use (not tested)
extract(value(c),'/article/article_body_page_html/text()').getClobVal()to get around this problem and ensure the extracted data is always treated as a clob by Oracle.

XML input: Node

hi experts.
          I can't create an XML input file for my custom BO with node items.
          When I export the XML file from the schema, a warning pops up showing that it is not exportable.
          Is it because of the schema that I created from Service Integration?
Regards,
May T.

Hello Fred and thank you very much for your help!
That is exactly what I did.
Here is the code of my staging Expense report, the dummy BO:
import AP.Common.GDT as apCommonGDT;
import AP.ExpenseReimbursementManagement.Global as ERM;
businessobject StagingExpenseReport {
        element MyInputrow: ID;
        element MyExpenseReportID: ExpenseReportID;
        element MyEmployeeID: EmployeeID;
        element MyExpenseReportTypeCode: ExpenseReportTypeCode;
        element MyPeriod: UPPEROPEN_LOCAL_DateTimePeriod;
        element MyDescription: LANGUAGEINDEPENDENT_EXTENDED_Text;
        element MyReferenceExpenseReportReceiptID: ID;
        element MyReceiptTypeCode: ExpenseReportExpenseTypeCode;
        element MyReceiptCategoryCode: ExpenseReportExpenseCategoryCode;
        element MyAmount: Amount;
        element MyPaymentAmount: Amount;
        element MyNetAmount: Amount;
        element MyReceiptDate: Date;
        element SameExpenseReport: Indicator;
But with this BO structure you can only create one Item/Receipt in each Staging Expense report. [1-1] relationship as everything is in the Root node.
So for example, in order to get a standard expense report with 2 receipts, I would need to create two instances of my Staging/dummy BO from the XML, each with one receipt. And using the ABSL to find which dummy BO goes to which Expense Report.
Am I mistaking or I understood well?
Because the thing is we cannot XML upload a child node in a custom BO neither if I got it right.
Thank you very much for your attention.
Best regards.

Binary tree - counting nodes

i have got a binary tree and i need to write a method which can count the number of leaves.
i have written the code as
static int countLeaves(BinaryNode node) {
        if (node == null) {
            return 0;
        else if (node.left == null && node.right == null) {
            return 1;
        return countLeaves(node.left) + countLeaves(node.right);
}but, how can i put the method in the main funcion, i have tried
int leafCount = countLeaves(root);it gives an error message "non-static variable root cannot be referenced from a static context". How can i solve this problem? Thank you.

the code looks like:
public class BinaryTree<AnyType>
    public BinaryTree( )
        root = null;
    public BinaryTree( AnyType rootItem )
        root = new BinaryNode<AnyType>( rootItem, null, null );
    public void printPreOrder( )
        if( root != null )
            root.printPreOrder( );
    public void printInOrder( )
        if( root != null )
           root.printInOrder( );
    public void printPostOrder( )
        if( root != null )
           root.printPostOrder( );
    public void makeEmpty( )
        root = null;
    public boolean isEmpty( )
        return root == null;

        if( t1.root == t2.root && t1.root != null )
            System.err.println( "leftTree==rightTree; merge aborted" );
            return;
        if( this != t1 )
            t1.root = null;
        if( this != t2 )
            t2.root = null;
    public BinaryNode<AnyType> getRoot( )
        return root;
    private BinaryNode<AnyType> root;
    static int countLeaves(BinaryNode node) {
        if (node == null) {
            return 0;
        else if (node.left == null && node.right == null) {
            return 1;
        return countLeaves(node.left) + countLeaves(node.right);
    static public void main( String [ ] args )
        BinaryTree<Integer> t1 = new BinaryTree<Integer>( 1 );
        BinaryTree<Integer> t3 = new BinaryTree<Integer>( 3 );
        BinaryTree<Integer> t5 = new BinaryTree<Integer>( 5 );
        BinaryTree<Integer> t7 = new BinaryTree<Integer>( 7 );
        BinaryTree<Integer> t2 = new BinaryTree<Integer>( );
        BinaryTree<Integer> t4 = new BinaryTree<Integer>( );
        BinaryTree<Integer> t6 = new BinaryTree<Integer>( );
        t2.merge( 2, t1, t3 );
        t6.merge( 6, t5, t7 );
        t4.merge( 4, t2, t6 );
        // i want to run the method countLeaves here
        int leafCount = countLeaves(root);
        System.out.println("Number of leaves: "+leafCount);
}

Can anyone help me to give the disassemble code to do it

Hi,
You can write your own Custom Disassemble Pipeline Component
which will break a message into batch of multiple messages. Batch size can be configured at pipeline design time by Implement members of IPersistPropertyBag interface.
The Scenario provided in the below link is exactly the same as your requirement. You just need to do few tweaks to the
code.

John,
Look at the XMLData object in the Acrobat JavaScript Scripting Reference. This might give you
the capability you're looking for. I've never used it...I just know of its existence.

Counting Nodes

Noob question.
This statement:
var nTableLength = TableKM.nodes.length;
is intended to count the child objects (rows) of a table which in my case should be a value of 3.
But the value in the debugger indicates that it is counting the children of the rows which are cells, a value of 6.
Is there a way to limit the counting to immediate child objects?
Thx.

You want to count the rows as they are the repeating object, not the table. If you had repeating tables your code would work.
And for .length I think you might need to use resolveNodes() (I'm at home now, just going off the top of my head):
var oRows = xfa.resolveNodes("TableKM.Row1[*]");
var nLength = oRows.length;
You can also use the Instance Manager to count:
var nLength = TableKM._Row1.count;

Unable to count nodes

Hi,
In a BPEL process I am working on there is an assignment activity where I assign the count of nodes as a result of a database query. This assignment is failing and am not able to figure out why.
Here is the bpel fragment for the assignment
*<assign name="Assign_1" bpelx:validate="yes">*
*<copy>*
*<from expression="ora:countNodes(bpws:getVariableData('Receive_1_receive_InputVariable','VvwshFmsHeadersCollection','/ns3:VvwshFmsHeadersCollection/ns3:VvwshFmsHeaders/ns3:vvwshFmsDetailsCollection/ns3:VvwshFmsDetails'))"/>*
*<to variable="FMSDetailCount"/>*
*</copy>*
*</assign>*
I am polling the database for some parent-child records. The intention is to count the number of child records in the collection.
Thanks in advance for your time and help. Please let me know if additional information is required.

Hi,
Just to be sure, my first solution is different from your solution, this is the one you tried ?
Mine : ora:countNodes('Receive_1_receive_InputVariable','VvwshFmsHeadersCollection','/ns3:VvwshFmsHeadersCollection/ns3:VvwshFmsHeaders/ns3:vvwshFmsDetailsCollection/ns3:VvwshFmsDetails')
Yours : ora:countNodes(bpws:getVariableData('Receive_1_receive_InputVariable','VvwshFmsHeadersCollection','/ns3:VvwshFmsHeadersCollection/ns3:VvwshFmsHeaders/ns3:vvwshFmsDetailsCollection/ns3:VvwshFmsDetails'))

I want the extract the ids from the table where pmt contains the child node (asset) contains .zip
for example http://download.p4c.abc.com/files/4/46pfl8008s_12/46pfl8008s_12_qsg_deu.zip
Then, I tried like this...
select r.* from
   (SELECT xmltype(pmt) object_value
                 FROM PRODUCT_TR_PMT
                 XMLTABLE
                                 'for $Product in $TEST/Products/Product/Assets/Asset
                                     return <RESULT>
                                               $Product
                                            </RESULT>'
                                 passing OBJECT_VALUE as "TEST"
                                 columns Asset path 'Asset'
                             ) r;
ORA-02263: need to specify the datatype for this column
Could you kindly help.
Thanks

Blob storage we (db folks) dont have any control its from application standard design.
If necessary, i can create function blob to clob.
Kindly help me in extracting child node which contains zip.
   select r.* from
   (SELECT xmltype(pmt) object_value
                 FROM PRODUCT_TR_PMT
                 XMLTABLE
                                 'for $Product in $TEST/Products/Product/Assets/Asset
                                     return <RESULT>
                                               $Product
                                            </RESULT>'
                                 passing OBJECT_VALUE as "TEST"
                                 columns Asset varchar2(255) path 'Asset'
                             ) r;
ORA-06553: PLS-306: wrong number or types of arguments in call to 'XMLTYPE'Thanks
