Get Length of Child Elements

I have an element called <Transaction>. This element has child elements within it. How can I get a length or count of how many child elements are within the <Transaction> element using PL/SQL?
Thanks
Jennifer

presume l_node_listg is a xmldom.DOMNodeList
and p_node is the xmldom.DOMNode of which you
want the amount of children
l_node_list := xmldom.getChildNodes(p_node);
amount := xmldom.getLength(l_node_list);
amount represents the number of children...
mind that #text and #comment children are not seen/accepted as REAL childs !! so only NODES will be taken in account !
hope this will help....
bye

Getting XML child elements

Dear Indesign scripters,
This script is making from all the XML tags ParagraphStyles.
But it refuses to take the child elements. Do I have to use XPath expression? And how?
function main() {
var xes, n, doc, ps, xe;
if ( !app.documents.length ) return;
doc = app.activeDocument;
xes = doc.xmlElements[0].xmlElements;
n = xes.length;
while ( n-- ) {
xe = xes[n];
st = doc.paragraphStyles.itemByName (xe.markupTag.name );
!st.isValid && doc.paragraphStyles.add({name:xe.markupTag.name});
main();
The XML
<Workbook>
     <Element_A_01>
          <Element_A_01></Element_A_01>
     </Element_A_01>
     <Element_B_02>
          <Element_B_02></Element_B_02>
     </Element_B_02>
</Workbook>
Greetings from Holland

The code creates two paragraph styles namely Element_A_01 and Element_B_02. These two are created for the immediate child nodes of the Workbook node. Now it seems that you are trying to create pstyles for all the nodes in the XML, which in your case would still be these two as Element_A_01 has a child node that is also named Element_A_01 and the same is the case for Element_B_02.
If i get your point right then you need to create 4 pstyles if all the nodes have different names, but that is not working. For this you will have to recursively traverse each node that you get from the code xes[n].
The code be something like this
function main() {
var xes, n, doc, ps, xe;
if ( !app.documents.length ) return;
doc = app.activeDocument;
xes = doc.xmlElements[0].xmlElements; //This gives the immediate child nodes of the Workbook node, hence the length in the next statement is 2
n = xes.length;
while ( n-- ) {
xe = xes[n];   //Here you need to recursively traverse the node xe
//The no of child elements of xe can be obtained as xe.xmlElements.length
//First element can be obtained by xe.xmlElements[0]
main();
Hope this solves the issue

How get all child elements from XML

Hi
I have one xml i tried to parse that xml using dom parser and i need to get some child elements using java
<Group>
<NAME>ABC</NAME>
<Age>24</AgeC>
---------some data here......
<Group1>
<group1Category>
<NAME>ABCTest</NAME>
<age>27</Age>
----Some data here
<group1subcategory>
<subcategory>
<NAME>ABCDEF</NAME>
<age>28</Age>
my intention was
get group name (here ABC) i need all other name value from group1category ,group1 subcategory but pblm that
my xml contains any number of Group nodes...but only i want name contains ABC
i wriiten code like this
DocumentBuilderFactory factory = DocumentBuilderFactory
.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(xmlFile);
NodeList nodeList = document.getElementsByTagName("*");
for (int i = 0; i < nodeList.getLength(); i++)
Element element = (Element) nodeList.item(i);
what is next step i need to do..please help

Child element of target node in message mapping getting suppressed

Hello All,
I am having mapping where i am trying to generate the target node based on some condition of the source structure ,this is working fine ,I am able to generate the target node once the condition gets satisfied ,but the problem is one of the child elements of the same node is not getting populated,its getting suppressed,i have some condition for the same
I checked the queues its showing value as
SUPPRESS
Value
Value ( in grey )
But still element is not getting generated..
I have added a condition used at the node function and apart from other condition of element..
If some body have the solution for the same,please help me out
Thanks in advance
Rajesh

Hi Rajesh,
The Error is mostly cause of that the node and your child are in same context.
You got to remember that the parent node creates the context, and then the child element puts the value in it.
Try putting your child element to a higher context then mapwithdefault for your supress and then removecontext.
This Issue, you got to work it out with the node functions,
I had the same kind of issue in my mapping, it was rectified with the help of node functions as mapwithdefault, removecontext.
Further unless one sees the mapping of your issue it is a bit difficult to imagine it and answer it.
For more clarifications please give the full hierarchy, and the condition. As of now try with the node functions.
Thanks

Order of elements - how to get position of child ?

Hi,
I would like to check, if the name of the second element of root is "youngestSon". Is it possible to query this with xpath (I use xquery with xpath-expressions, in fact I already know the name of the element but want to get sure with an exist-statement, that the element's position is 2) ?
<parent>
<oldestSon>A</oldestSon>
<youngestSon>B</youngestSon>
</parent>
Note, that the child element names are different. What I dont need is the second son in the following example (therefor I could use /parent/son[position()==2] )
<parent>
<son>A</son>
<son>B</son>
</parent>
Thank you for any help!

}i want to get child elements. but its throwing exception on typecasting. can u tell me why?

thanks for the info.
i got 2 solutions
SOLUTION 1:
public class Test {
     public static void main(String[] args) throws Exception {
          Document doc = null;
          System.out.println("!!!");
          try {

         NodeList nl = e.getChildNodes();
         int count = 0;
         System.out.println(nl.getLength());
         for(int i=0;i<nl.getLength();i++){
                  Node n = nl.item(i);
                 //System.out.println(n.getClass().getName());
                 //System.out.println((Element)n);
                 if(n instanceof Element){ // this checks for node type
                      count++;
                      System.out.println("Element "+(Element)n);
SOLUTION 2: :
XPath xpath = XPathFactory.newInstance().newXPath();
         InputSource inputSource = new InputSource("test.xml");
         NodeList nodes = (NodeList) xpath.evaluate("//GenericDataSource/*", inputSource, XPathConstants.NODESET);

-Sookie

Hi Sookie,
I found the problem is with couple of child parameters are not registered the deserializer. There're couple of additional classes needs to be registerd.
// register the TemplateLabelValue class
QName templateval = new QName(bipNamespace, "TemplateFormatLabelValue");
Class cls = TemplateFormatLabelValue.class;
call.registerTypeMapping(cls, templateval, BeanSerializerFactory.class, BeanDeserializerFactory.class);
// register the TemplateLabelValues class
QName templatevals = new QName(bipNamespace, "TemplateFormatsLabelValues");
cls = TemplateFormatsLabelValues.class;
call.registerTypeMapping(cls, templatevals, BeanSerializerFactory.class, BeanDeserializerFactory.class);
Could you please give it a try?
Thanks.

How to get the number of elements in a tilelist

I'm writing test cases for a flex application using FlexSelenium and I need to get the number of elements displayed in the tilelist.
I know that that the tilelist is fed by an array. but i can't access that array from my test case.
Can anyone tell me how I can get the number of elements in a tilelist on the application? which property of the tilelist can provide that number?

try tileList.dataProvider.length;

How to get data from a element?

Hi!
I'm try to get data in an element, below is my xml document
<?xml version="1.0" encoding="UTF-16" ?>
<!ELEMENT Group (GID, Description?)>
<!ATTLIST Group Name CDATA #REQUIRED>
<!ELEMENT GID (#PCDATA)>
<!ELEMENT Description (#PCDATA)>
<?xml version="1.0" encoding="UTF-16" ?>
<!DOCTYPE Group SYSTEM "group.dtd">
<Group Name="AdminGroup">
<GID>000</GID>
<Description>System administrating group</Description>
</Group>
And I try to get data of GID:
NodeList nlx = doc.getElementsByTagName("GID");
Node nodex = nlx.item(0);
System.out.println("Element Node name: "
nodex.getNodeName()"]");
System.out.println("Element Node value: ["
nodex.getNodeValue()"]");
the output is:
Element Node name: [GID]
Element Node value: [null]
How can I get the data of GID("000")??

nodex is a node of type Node.ELEMENT_NODE, now to access the value of that node you should go through the collection of childs of this node and locate the one with type Node.TEXT_NODE (there should be only one child anyway) and there you can ask for the value. That translated into code should be something like:
NodeList childs = nodex.getChildNodes();
for ( int i = 0; i < childs.getLength(); i++ ) {
Node childNode = childs.item( i );
     int type = childNode.getNodeType();
     if ( type == Node.TEXT_NODE )
          System.out.println("Element Node value: ["+childNode.getNodeValue()+"]");

Removing xmlns in child element

Hi,
I am getting xmlns="" in child , i want to remove the xmlns="" from the child element.
Ex: Generated XML File-
<GENERATEFILES xmlns="http://getit.com/generatedFile" >
<GENERATE xmlns="">
</GENERATE >
</GENERATEFILES >
in the code i have added Namespace to display 'xmlns' in' GENERATEFILES ' element,
Element root = new Element("GENERATEFILES ");
Namespace IP_NAMESPACE = Namespace.getNamespace("", "http://getit.com/generatedFile");//added xmlns for GENERATEFILES .
root.setNamespace(IP_NAMESPACE);
Element child = new Element("GENERATE ");

EJP wrote:
The XML means the same thing with and without the internal namespace declarations.I don't believe that's true. If I'm not mistaken, the GENERATEFILES element is in the "http://getit.com/generatedFile" namespace. And since this namespace is declared to be the default namespace, then the GENERATE element would inherit that namespace unless some other declaration was provided. In the example posted there is another declaration provided on the GENERATE element, namely one which declares that the element is in no namespace.
If the OP gets his wish of not having that declaration present, that would result in the GENERATE element also being in the "http://getit.com/generatedFile" namespace, which can (as I believe you meant to say) be arranged by creating the GENERATE element in that namespace.
However the real question for the OP is "What namespace should the GENERATE element be in?" Attempting to control the namespace declarations without understanding them is a bad idea.

I am new in indesign scripting, please tell me how to write a script to get content of a element in xml and then sort all the content

Hi,
May the below code is useful for you, but I dont know how to sort.
Edit the tag as per your job request.
alert(app.activeDocument.xmlElements[0].contents)
//Second alert
var xe = app.activeDocument.xmlElements[0].evaluateXPathExpression("//marginalnote");
alert(xe.length)
for(i=0; i<xe.length; i++)

XML element,if not including any attributes and/or child elements then

XML element in SQLX,if not including any attributes and/or child elements then the tag should not appear, how to achive this?
ex:Consider for <enumeration> tag where it is having some value.
<attribute>
<name>Ethernet Access</name>
<enumeration>
<StringValue>Bandwidth</StringValue>
</enumeration>
</attribute>
When <enumeration> tag is not have any Value in this, then output should be as follows.
<attribute>
<name>Ethernet Access</name>
</attribute>
But what i am getting is
<attribute>
<name>Ethernet Access</name>
</enumeration>
</attribute>
Please suggest me the solution for this.
I tried , but when xmlelement() is not having data it will display empty tag ie </enumeration>, If xmlforest() are null it wont show tag, But i have to use xmlelement only. how can that be achived using xmlelement .

Use a SQL case - when - else end construct to only execute the xmlelement if data is present. The SQL/XML standard is very clear, xmlElement will generate an empty element if no data is present. xmlforest will not.

Any ideas about the cause and resolution?..
Thanks in advance!!!!

If you posted the whole WSDL file, it would be more helpful.
I suppose your WSDL uses rpc/encoding. Both operations in your WSDL expects only one parameter of xsd:float. Well your client code passed an array float(new Object[] {new Float(3)}).
This should have caused the exception.

Order By Clause For Retrieving Child Elements

Hi All,
I got a toplink question regarding adding an order by clause for retrieving the child elements in a 1 to many mapping.
I have an Order with a collection of Order Events. ( one to many mapping). The OrderEvent model is the super class of all events and it is abstract. The mapping for the order event descriptors has a class hierarchy mapping which uses a table for its super class (i.e OrderEvent abstract class) and different tables for its sub class elements (e.g ShippingEvent, LifeCycleEvent etc which are concrete classes).
If I add an order by clause to order the event by a spuerClassProperty in the super class descriptor, it gets ignored and the ordering is done by the alphabetic order of the indicator field values.
I also noticed that if there is more than one sub class instance for a specific class indicator value, the ordering by is observed.
I got around it with a Comparator, but just want to know if it could be possible to achieve this with toplink.
Regards.

Does the Order By appear on the SQL that get issued? TopLink only does ordering on the database, and not in memory. This means that subclass queries will be ordered per type, on not as one big list.
A Comparator is a good solution.
