Get Node Value in XSLT
Hi all.
Maybe a simple question but, I haven't done yet.
In BPEL, when I need to get a node, I use getVariableData XPath function, for example:
count(bpws:getVariableData('MtlSystemItemsBESB_OutputVariable','MtlSystemItemsBCollection','/ns7:MtlSystemItemsBCollection/ns7:MtlSystemItemsB')) to get the number of lines returned from the service call.
Now, when I use XSLT transformation in ESB, I don't have a variable to extract the value from. So, how do I use XPath expressions that involve node-set return values?
I tried something like count('/ns7:MtlSystemItemsBCollection/ns7:MtlSystemItemsB') but it does not seem to work.
Thanks
Denis
Hi Denis,
count('/ns7:MtlSystemItemsBCollection/ns7:MtlSystemItemsB') should work as expected. Have you double checked your XPath (namespace, elementnames, etc.)?

I have a tree with 3 level and it is working fine.. In view mode I need the First child value of the 3rd level with out clicking / Selecting from teh Tree node..
for eg;
A -- ist level
Ap -- 2nd level
Apple -- 3rd level
So What I need is that I should get a message 'Apple' While landing teh Form itself without clicking on teh Tree
Thanks in Advance...To my knowledge it is not possible to get the value of a node which is not selected.
What you have to do is to build up a memory structure similar to your tree, then you can access any node at any time.

Xml: how to get node value when pasing node name as a parameter
Hi,
I've got some xml:
var xmlData:XML =
<1stNode>
<buttonID>first child node value</buttonID>
<imageID>second child node value</imageID>
<labelID>third child node value</labelID>
</1stNode>
Then I want to read specific node value based on a value passed to a function. .
var buttonID = new Button;
var imageID = new Image;
var labelID = new Label;
getNodeValue(buttonID); //the value here is set dynamically
private function getNodeValue (nodeName:String):void {
trace (xmlData.nodeName) //doesn't work
var str:String = "xmlData." + nodeName;
var xml:XMLList = str as XMLList //doesn't work
I'm don't know how to get the value when node name is dynamically changed.use:
getNodeValue(buttonID); //the value here is set dynamically
private function getNodeValue (nodeName:String):void {
trace (xmlData[nodeName]) -
Getting Node Value of an XML element in JAVA.
Hi,
In my application, I have got the exact node that I want by parsing the document, but the node value returned is null as the node is an element and the Java Documentation does specify that it will return null. I would like to know if there in any alternative way by which I can parse the document and get the specified value of the node or element. Kindly help.Hi,
i am using the dom parser. My code is as follows.
Document xmlDocument, outputDoc;
DocumentBuilderFactory dbfObject = DocumentBuilderFactory.newInstance();
DocumentBuilder dbObject = dbfObject.newDocumentBuilder();
xmlDocument = dbObject.parse("IPD_Response.xml");
Element dd = xmlDocument.getDocumentElement();
NodeList ItemAttributes = dd.getElementsByTagName("Element Name");
System.out.println("element" + ItemAttributes.item(0));
Node ss = ItemAttributes.item(0);
NodeList bb = ss.getChildNodes();
Node cc = ss.getFirstChild();
System.out.println("element sibling1 "+bb.item(0));
System.out.println("element sibling 2"+bb.item(1));
System.out.println("element sibling 3"+bb.item(2));
System.out.println("element child "+cc);
Node aa = bb.item(0);
NodeList qqq = aa.getChildNodes();
System.out.println("element sibling1---1 "+qqq.item(0));
System.out.println("element sibling1---1 "+qqq.item(1));
Node fff = qqq.item(0);
Node aaa = qqq.item(1);
String value1 = fff.getNodeValue();
String value2 = aaa.getNodeValue();
System.out.println("1st value "+value1+" 2nd value "+value2);What my code does is gets all the elements within a particular tag. After that i look for the child nodes, which i have done successfully. But when i get the value using getNodeValue(); method it will be null as per the Java Docs. Is there any other way by which i can get the node value. Kindly help.
How do you parse the XML Document ?
Are you using a DOM Document ?

Getting Node Value of an XML document in JAVA.
Hi,
In my application, I have got the exact node that I want by parsing the document, but the node value returned is null as the node is an element and the Java Documentation does specify that it will return null. I would like to know if there in any alternative way by which I can parse the document and get the specified value of the node or element. Kindly Help.Well, there are not many mind readers on this forum.
You do not tell us how you are parsing the document, and so it is difficult determining why the node value is returned as a null.
There are two main styles of processing XML -- DOM and SAX. Dom (and its variants JDom and I think Dom4J) build a tree structure that is memory-resident. There are ways to walk up and down the tree, and locate arbitrary nodes in the tree.
The other style is SAX, which is much less intensive from a memroy perspective, but puts more work on you to keep what you want as the data goes flying by.
So, how are you "parsing the document" and what method is returning a null? That may give someone enough information to guess at your problem.

I want to read a XML file so am trying like this:
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
m_doc = docBuilder.parse("formular/faktura2.xml");
Element root = m_doc.getDocumentElement();
root.normalize();
NodeList list = root.getChildNodes();
for (int k=0; k<list.getLength(); k++)
Node nd = list.item(k);
System.out.println("node "+nd);
}The output of this code is:
<datatabel>
<navn>Tabel</navn>
<aktiv>1</aktiv>
<tabel>BILAGSPOSTER</tabel>
<kolonne>
<navn>VareNr</navn>
<hoved>VareNr</hoved>
<bredde>50</bredde>
<aktiv>1</aktiv>
</kolonne>
<id>1</id>
<fontNavn>Verdana</fontNavn>
<fontStr>12</fontStr>
<fontFed>0</fontFed>
<fontKur>0</fontKur>
<fontUnd>0</fontUnd>
<posX>83.0</posX>
<posY>463.0</posY>
<bredde>440.0</bredde>
<hoejde>150.0</hoejde>
</datatabel>
But how do I get the values inside nodes? I tried with getNodeValue() but then the only output I get is null. Can someone plz help me with this?Try this:
/** Lists a node and its childs */
public static void listNodes(Node root) {
System.out.println("Node "+root);
if (!root.hasChildNodes()) return;
NodeList nodes = root.getChildNodes();
for (int k=0; k<nodes.getLength(); k++) {
listNodes(nodes.item(k));
}Hope this helped,

Hi All,
I am new to BPEL and had been struggling to get the value of a particular node from a list of nodes.
My XML looks like:
<ns2:attributes>
<ns2:Name>Known AS</ns2:Name>
<ns2:Value>Known as</ns2:Value>
</ns2:attributes>
<ns2:attributes>
<ns2:Name>Junk1</ns2:Name>
<ns2:Value>junlk1</ns2:Value>
</ns2:attributes>
<ns2:attributes>
<ns2:Name>Business Unit</ns2:Name>
<ns2:Value>BUUnit</ns2:Value>
</ns2:attributes>
<ns2:attributes>
<ns2:Name>Cost Center</ns2:Name>
<ns2:Value>100000</ns2:Value>
</ns2:attributes>Now my requirement is that I want to get the value of the node named 'Cost Center' only. One way which I have it working as of now is to get a count of the total number of nodes and then in a while loop iterate over all the nodes and use a switch condition to check for the node name = 'Cost Center' and then get the value.
I was wondering if I can do something like below or any other way by which I can get the position based on node name (something like search functionality)
bpws:getVariableData('inputVariable','payload','/ns3:process/ns4:BeneficiaryDetails/ns4:attributes[@name='Cost Center']/ns4:Value') Thanks,
BikashHi Bikash,
This should do...
bpws:getVariableData('inputVariable','payload','/ns3:process/ns4:BeneficiaryDetails/ns4:attributes[ns4:Name = "Cost Center"]/ns4:Value')The quotes around "Cost Center" may need to be escaped...
Cheers,

At value of XML node i want to put the value of one xml node. is there any function in transform to get the content of node.
Thanks
vivek
Edited by: 809104 on Nov 14, 2010 9:29 PMI got the solution
we can use variable inside transform and assign xpath value to that variable then we can use that variable inside test condtition
<xsl:variable name="name" select="xpath"/>
<xsl:when test="\ns0:data = $name">
</xsl:when> -

Extracting node value from XPath Expression in OSB Conditional Branch
HI All
While using conditional branch in OSB,i only get an XPath Expression editor to set a variable used to test a condition.
Now let's say my request is
<Body>
<exam:PersonSearchReq xmlns:exam="http://www.example.org">
<exam:RequestorSSO>James</exam:RequestorSSO>
</exam:PersonSearchReq>
</Body>
I write my XPath expression as :
./exam:PersonSearchReq/exam:RequestorSSO/text()
Now if I test this using the tester application , insted of getting node value 'James' ,i get the entire node element ,i.e
<exam:RequestorSSO xmlns:exam="http://www.example.org">James</exam:RequestorSSO>
Please suggest how can i extract the text value.
Regards,
ChinmayHi Guys
Actually it turns out that you need to populate In-Variable to function is correctly.As soon as i entere 'body' in it,it worked fine.
Thanks

Hi,
Is there any method to get node value other than getTextContent() in org.w3c.dom.Node?
Here is my XML
<data>value<data>
Hoe can i get "value" using java?
Thanks
ShagilThe text "value" is a child node of element node "data". So, by following the tree structure of DOM, you'll get this text by asking for the node value of the (first) child node of the element.
Node data = ...;
if (data.hasChildNodes()) {
String text = data.getFirstChild().getNodeValue();
// use text

Is it better to use Invoke nodes or property nodes to set/get control values?
I have a series of VI's that run in parallel, each to manage different functions- pumping, sensing, a fluid flow model, an experiment generator/runner.
These need to exchange data, which I am currently doing using invoke nodes (that are all in subVIs), using methods "Set control value" and "Get control value". I find that every now and then (perhaps 1% of the time) the data isn't exchanged correctly and therefore the system doesn't work. I can imagine how "set" could go wrong if they happen simultaneously, and can devise ways of preventing this. However, the "Get" method suffers from the same problem. This is a major problem, because I want to leave it running for several hours.
I could in
principle achieve the same thing using property nodes and find myself wondering if this might be more reliable. But I don't want to change over only to find it makes no difference!
Can anyone advise?You can use some kind of syncronization such as queues, occurances, or notifiers but I think the easiest way would be to create and action engine. This was only one action can execute at a time avoiding a "race condition". Possibly a write action and a read action might help. You also can add queues or notifiers into this concept. hope this helps.

Getting null values from nodes using DOMParser
Hi
I'm having problems retrieving the values from an XML doc.
I'm using the DOMParser, but instead of retrieving the values
from the nodes, I just get null.
Code fragment :
DOMParser parser = new DOMParser();
parser.parse(url);
XMLDocument doc = parser.getDocument();
NodeList nl = doc.getElementsByTagName("*");
Node n;
iNode = nl.getLength();
for (int i=0; i<iNode; i++)
n = nl.item(i);
String szNodeName = n.getNodeName();
System.out.print(szNodeName+ " (" );
System.out.print(n.getNodeValue()+")");
System.out.println();
The result is
course (null)
Name (null)
All the node names are correct, but the node values are NOT
displayed.
Any idea ?
Rodrigo
nullAccording to the DOM Level 1 spec, the "value" of an ELEMENT node
is null and the getNodeValue() method will always return null for
an ELEMENT type node. You have to get the TEXT children of an
element and then use the getNodeValue() method in the text nodes.

Getting the value of a child node in an array
How do you get the value of a child node in an array titled "entries"? I used to do this in AS2, and now I'm trying in AS3. To top it off, I'm forced to use an XML format I'm unfamiliar with. So I'm not sure how to access these nodes in AS3. An example of the XML is;
<Row>
<Cell><Data ss:Type="String">Absorption Areas</Data></Cell>
<Cell><Data ss:Type="String">Drain fields where left over liquid from the septic system soak into the ground.</Data></Cell>
</Row>
How would I access ether of the <Cell> rows?
ThanksGiven that you declared ss namespace (otherwise it will throw an error) you have two options:
xml.Cell[0].Data - will output:
Absorption Areas
xml.Cell.Data will output:
<Data ss:Type="String">Absorption Areas</Data>
<Data ss:Type="String">Drain fields where left over liquid from the septic system soak into the ground.</Data>
So, xml.Cell.Data[1] will output:
Drain fields where left over liquid from the septic system soak into the ground.
