Using XSLT to extract value of a XML node with namespace

I have a XML source code here.
<?xml version="1.0" encoding="utf-8" ?>
<rss version="2.0" xmlns:job="http://www.pageuppeople.com">
<channel>
    <title>SMH Jobs</title>
    <link>internalrecruitment.smhgroup.com.au/jobsrss.ashx?stp=di</link>

      <job:location PUReferenceID="3711">Sydney - Inner Suburbs & CBD</job:location>
    </item>
</channel>
</rss>
I want to use XSLT to extract value of a XML node with namespace <job:location>, and the returned value should be string 'Sydney - Inner Suburbs & CBD'. I tried a few XSL code below, but failed with error or nothing was returned.
<xsl:value-of select="job:location" disable-output-escaping="yes"/>
<xsl:value-of select="job/location" disable-output-escaping="yes"/>
<xsl:value-of select="job\location" disable-output-escaping="yes"/>
<xsl:value-of select="location" disable-output-escaping="yes"/>
This might be an easy question for you, but I would appreciate if anyone can help.

Hi Suncorp IT Learner,
We need to tell the XSLT that some elements are in another namespace. Copy the xmls declarations for the prefixes you need to use. Then use the xsl format as:
<xsl: value-of select=”job:location/@PUReferenceID”/>
In following issue, Chriztian has a good explanation:

How to set the value in the xml node.

Hi
I am having the application PDF which can be submitted by user using the button. while submitting
i am using below code to set the value in the xml node.
xfa.data.assignnode("employee.id","123",0):
So its generating the xml like below.
<employee>.
<id>123</id>.
</name>
</employee>
Now i need to generate the xml like below.
<employee id= "123" >
</Name>
</employee>
So how to set/create the id node like above?
Advance Thanks.
Regards,
Dhiyane

Hi Dhiyane,
You will have to set the contains property if the id node to "metaData", that is;
xfa.data.assignNode("employee.id","123",0);
xfa.data.employee.id.contains = "metaData";
Very clumsy if you have a number of them, in which case you might want to look at using E4X.
Good luck

Hi,
You need to declare the namespace of each element used in the XPath expression, like this :
SQL> select extractvalue( XMLDATA
2                     , '/samp:Field1/UTI/U01'
3                     , 'xmlns:samp="http://www.oradev.com/chipsxml.xsd"' ) "XMLDATA"
4 from chipsxmltable1 x
5 ;
XMLDATA
No
SQL> select extract( XMLDATA
2                , '/samp:Field1/UTI'
3                , 'xmlns:samp="http://www.oradev.com/chipsxml.xsd"'
4                ).getstringval() "XMLDATA"
5 from chipsxmltable1 x
6 ;
XMLDATA
<UTI>
<U01>No</U01>
<U02>Y</U02>
<U03>Y</U03>
<U03a>Y</U03a>
<U03b>Y</U03b>
<U03c>Y</U03c>
<U04>Y</U04>
<U05>Y</U05>
</UTI>
Please see EXTRACT and EXTRACTVALUE documentation :
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/functions051.htm#i1006712
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/functions052.htm#SQLRF06173
BTW, "XMLDATA" is a pseudo-column used by Oracle. I don't know if it'll ever cause any conflict but maybe you should rename your column.

Using XPATH to extract value.

I need some help to extract the LatestFillQuantity element value using XPATH.
in Java.
I am unable to extract the value of 10000.
Please help as to what have I done wrong.?
The Document configNode contains the flwg:
<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<i:Interest >
     <i:Generation>3</i:Generation>
     <i:Extension>
        <i:Active.From/>
        <i:Order>
          <i:Status>Confirm</i:Status>
          <i:LatestFillQuantity>100</i:LatestFillQuantity>
        </i:Order>
</i:Extension>
</i:Interest>
My Java Code
private void extractValue(Document configNode)
     XPathFactory factory = XPathFactory.newInstance();
        XPath xpath = factory.newXPath();
          try{
         XPathExpression expr
          = xpath.compile("//i:Order/i:LatestFillQuantity/text()");
         Object result = expr.evaluate(configNode, XPathConstants.NODESET);
         NodeList nodes = (NodeList) result;
         for (int i = 0; i < nodes.getLength(); i++) {
             System.out.println(nodes.item(i).getNodeValue());
         }catch(Exception e){
              System.out.println("Sorry,this aint working");
     }

The nodes being parsed are namespace prefixed.
To parse a namespace node with the JDK 5.0 javax.xml.xpath package, set the NamespaceContext on the XPath object.
An implementation of NamespaceContext with a single prefix corresponding to a namespace uri:
public class NamespaceContextImpl implements NamespaceContext{
public String uri;
public String prefix;
public NamespaceContextImpl(){}
public NamespaceContextImpl(String prefix, String uri){
     this.uri=uri;
     this.prefix=prefix;
public String getNamespaceURI(String prefix){
   return uri;
public void setNamespaceURI(String uri){
   this.uri=uri;
public String getPrefix(String uri){
   return prefix;
public void setPrefix(String prefix){
   this.prefix=prefix;
public Iterator getPrefixes(String uri){return null;}
}

How to search for a text node with a particular value in an xml document with labview

supposing i have the following xml document:

<book>
<bookname>the spear warrior</bookname>

i want to search for the author of the book "the beard" using for example the V.I Get first match of labview to access the the node with value "the beard" and then use Get next sibling V.I and Get node text content to get get the author of this book..so my question is how do i write the xpath expression for Get first match so as to access the node with bookname "the beard" instantyly? am trying to minimise the use of loops because they increase the time duration,..thank you (NB:i dont want to use Get all Matched V.I because it obliges me to use a loop in order to access the name derrick and this increases the time duration for my v.i)
Solved!

Since it's all text, why not use a real quick Match Pattern (or Regular Expression, but you don't need that much power here), see attached.

Getting null value while parsing "XML String" with encoding WINDOWS-1252.

Hi,
when I am converting the Follwoing "xml string " to Document, I am getting the "null" as a document value.
    String strXML = "<?xml version="1.0" encoding="WINDOWS-1252"?>
                          <category name="SearchByAttributes" value="Search By Attributes">
                            <item name="ORDER_LINE_ID" description="Application Search Attributes" >
                               <attribute name="Sequence" value="0001"/>
                             </item>
                            </category>"
My "xml string" has the encoding vaule: WINDOWS-1252.
I am using the following code to convert the "xml string" to Document. I am getting the Document values as a "null" while converting the above "string xml"
        String strXML = //my above string xml.
        DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
        docBuilderFactory.setIgnoringElementContentWhitespace(true);
        docBuilder = docBuilderFactory.newDocumentBuilder();
        doc = docBuilder.parse(new InputSource(new StringReader(strXML)));
        System.out.println("doc value.."+doc)//I am getting null value for "doc".
Can anyone help me to resolve the issue.

//getting Element Attribute list as an...."null"(I am expecting output value object reference but it is printing "null"
(without the rest of the code, i'm guessing that) most likely you are grabbing the first child node of the item element. however, you are not accounting for some text nodes that are most likely in that list, like the whitespace between the item element and the attribute element. please go read some tutorials on xml, there are thousands of them out there, and they will answer all you initial questions much more efficiently than posting each step to the forums.

Is it possible to create indexes & use them on xml docs with namespaces?

I have put an XML doc in a BDBXML container which looks like this:
*<ns1:note xmlns:ns1="http://www.testsch.org/ns">*
*<ns1:to>Eric</ns1:to>*
*<ns1:from>Brendan</ns1:from>*
*<ns1:msg>How r u?</ns1:msg>*
*</ns1:note>*
Now, I am creating an index on the element "to", as:
addIndex "ns1" "to" node-element-equality-string
Though the index has been shown as getting created using the listIndexes command, if I lookup that index with the following command:
lookupIndex node-element-equality-string "ns1" "to"
the output is:
*0 objects returned for eager index lookup 'node-element-equality-string'*
Whereas, if I do the whole procedure without the namespaces in the document & the commands, the result is fine:
*1 object returned for eager index lookup 'node-element-equality-string'*
Can someone please tell me whether using namespaces, the indexes can be created or not? If yes, how?
Thanks,
Dev
Edited by: user11871332 on Sep 7, 2009 3:53 PM

Hi Dev,
When using XML, the prefix for the namespace is really just syntactic sugar. The actual namespace in your example is "http://www.testsch.org/ns", and that's the value that you need to use when creating your index:
addIndex "http://www.testsch.org/ns" "to" node-element-equality-stringJohn

Add indent spaces to xml nodes with ms IXMLDOM

Hi All,
Currently I was update a xml file with IXMLDOM, after add nodes to xml file, we found the new added node was written in one line always. this make it hard to find the differences with merge tools.
and after we try to add text node to the xml to format it, it works unless we added nested nodes, it looks like:
<RootNode>
<ChildNodes>
<Child>value</Child></ChildNodes></RootNode>
Ugly, huh
And, when we set node's type with IXMLDOMNode::put_dataType it makes the node like:
<Name xmlns:dt="urn:schemas-microsoft-com:datatypes" dt:dt="string" Encoding="Standard" >Connections</Name>
but, the original nodes was:
<Name dt:dt="string" Encoding="Standard" xmlns:dt="urn:schemas-microsoft-com:datatypes">Connections</Name>
Also, it will not affect the its function, just cause extra efforts to merge the results.
So my questions:
1. is there any built-in functions that can be used to format the xml file to a indented version.
2. how to adjust the sequences of attributes of a node.
Thanks,
Levi

Parsing XML Node with href attribute

Hi,
I have the following XML that has to be parsed using JSP DOM. All fine except for one. The only problem that i have is when to parsing the Node with href attribute.
I am using the following method, and it returned with weird result
currNode.getAttributes() ====> the result is com.sun.org.apache.xerces.internal.dom.AttributeMap@111ae04
currNode.getNodeValue() ====> the result is null
currNode.TextNode ===> it returned *2*
Can anyone please let me know what did I miss here? What should I do to parse the href attribute into the jsp page?
The below is the xml.
<MovieList>
<Movie href="DarkKnight.xml">
   <head>
         <Title>Batman Dark Knight</Title>
         <Genres>
               <Genre>Action</Genre>
               <Genre>Sci-Fi</Genre>
         </Genres>
         <Description>Movie Details here</Description>
   </head>
</Movie>
</MovieList>Thanks

I am not sure what "JSP DOM" is exactly. In the W3C DOM supported since SUN Java 1.4 if you have an element node and want to access an attribute value you can simply use String href = movieElement.getAttribute("href"); You might need to cast your Node to Element first e.g.Element movieElement = (Element)currNode;

How must getElementsByTagName work on an xml file with namespaces?

Hello together,
is there any normative document, which specifies
which nodes must be returned by
the org.w3c.dom.Document method
getElementsByTagName when which was
created by a namespace aware dom parser
from an xml file containing namespaces?
In other words:
when you have an xml file:
<someprefix:somenode xmlns:someprefix="http://someuri">
<someprefix:innertag>
<someprefix:mostinnertag>
</someprefix:mostinnertag>
<someprefix:mostinnertag>
</someprefix:mostinnertag>
</someprefix:innertag>
</someprefix>
and you call
document.getElementsByTagName( ... );
1) How many nodes must be returned when giving
"mostinnertag" as parameter?
2) How many nodes when giving "someprefix:mostinnertag" as parameter?
Is it allowed to use the "non namespaceaware"
method and not "getElementsByTagNameNS"?
I know:
a) xerces returns 2 nodes when using
alternative 2 and none with alternative 1
b) oracle xml parser returns 2 nodes when using
alternative 1 and none when using alternative 2
Which implementation is right?
Yours

I've got some problems with this methos and xerces too.
Perhaps the two implementations (xerces and oracle) are different. I mean xerces implementation gives you nodes of this name but without namespace and oracles's implementation gives you modes with namespace whose unprefix-name is "mostinnertag".

Selecting XML Children with Namespaces

I am trying to select child nodes of an XML element that have
a different namespace from the parent, but xml.child(name) returns
an empty list.
In the attached code, londonList contains a single XML
element and parisList is empty. I can't figure out how to find the
paris child, and have tried adding the prefix to findParis (so it
is "ff:b") as well as turning findParis into an XML object with the
name "b" and adding the ff namespace to it, then passing that to
child. Neither of those have worked.
Any help is appreciated.

Unfortunately in my real scenario I don't know what the
element will be called. It could be in <foo> or <bar>
etc, so I need to be able to use a variable (in which the element
name is set beforehand). With "::" I can't use a variable, so
textXML.ns::findParis looks for a "findParis" element and not "b".
That's why I'm trying to use testXML.child(findParis) because
I can use a variable. I just can't figure out how to make it
incorporate the namespace as well.

how to write a bean to get this xmloutput.
thank in advance

Hi Sliba,
You may download and use the XDK for Java that is available from OTN to do this.
Here is the code that will be handy for use. Just substitute your XML document and stylesheet
in the code snippet pasted below. I hope this helps.
There are many more useful XML samples you can find at http://otn.oracle.com/sample_code/tech/xml/content.html

Retrieve xml attribute value of nth xml node using xpath query

I have an xml with following stucture...
<xml>
<header>
<DocumentReference OrderId="order001">
<DocumentReference OrderId="order002">
<DocumentReference OrderId="order003">
I have to loop through this xml and retrieve the orderId values inside Biztalk orchestration.
In the expression shape, I get the count of 'DocumentReference' nodes using an xpath query and then
Added a loopshape to make sure it loops thru all nodes
Loop condition:   n<=nodeCount     (where n is an integer variable, n=0 to begin with, incremented by 1 thru each loop, nodeCount is # of DocumentReference nodes)
I try retrieve to the orderId in the following expression shape using the below xpath query
xpathQuery = System.String.Format("//*[local-name()='OrderReference'][{0}]/@orderID)",n);
sOrderId = xpath(MsgSingleInvoice,xpathQuery);
And I get the following exception:
Inner exception: '//*[local-name()='OrderReference'][1]/@orderID)' has an invalid token.
Exception type: XPathException
Appreciate any help!   thanks!

Thanks for the quick response. I got rid of it.
And I see a different error:
Inner exception: Specified cast is not valid. Exception type: InvalidCastException
Source: Microsoft.XLANGs.Engine
Target Site: System.Object XPathLoad(Microsoft.XLANGs.Core.Part, System.String, System.Type)
Since variable 'n' is of integer type, I suspected it and changed it to n.ToString() and tested again and still see the same error.

How to get a value from Specific XML Node

Hi all,
I'm just trying to introduce to XMLType and see the potencialities of that.
DB version:
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi
PL/SQL Release 10.2.0.5.0 - Production
CORE     10.2.0.5.0     Production
TNS for IBM/AIX RISC System/6000: Version 10.2.0.5.0 - Productio
NLSRTL Version 10.2.0.5.0 - Production
I'm a table with just one CLOB field:
CREATE TABLE asm_test
(doc XMLType NOT NULL)
XMLTYPE doc STORE AS CLOB;
Then i've inserted the following XML data:
<?xml version="1.0" encoding="UTF-8" ?>
- <ReceiptDesc>
<appt_nbr>2142473</appt_nbr>
- <Receipt>
<dc_dest_id>401</dc_dest_id>
<po_nbr>2142473</po_nbr>
<document_type>P</document_type>
<asn_nbr />
- <ReceiptDtl>
<item_id>509720</item_id>
<unit_qty>83.0000</unit_qty>
<receipt_xactn_type>R</receipt_xactn_type>
+ <receipt_date>
<year>2012</year>
<month>09</month>
<day>17</day>
<hour>15</hour>
<minute>33</minute>
<second>49</second>
</receipt_date>
<receipt_nbr>6902340</receipt_nbr>
<container_id>1</container_id>
<to_disposition>ATS</to_disposition>
<user_id>NTCPO01</user_id>
<catch_weight />
</ReceiptDtl>
- <ReceiptDtl>
<item_id>509740</item_id>
<unit_qty>17.0000</unit_qty>
<receipt_xactn_type>R</receipt_xactn_type>
+ <receipt_date>
<year>2012</year>
<month>09</month>
<day>17</day>
<hour>15</hour>
<minute>33</minute>
<second>49</second>
</receipt_date>
<receipt_nbr>6902344</receipt_nbr>
<container_id>1</container_id>
<to_disposition>ATS</to_disposition>
<user_id>NTCPO01</user_id>
<catch_weight />
</ReceiptDtl>
</Receipt>
</ReceiptDesc>
And then i have started to make some tests to retrieve data from.
SELECT EXTRACTVALUE(doc, '/ReceiptDesc/appt_nbr') FROM asm_test; -- got the correct value 2142473
SELECT EXTRACTVALUE(doc, '/ReceiptDesc/Receipt/dc_dest_id') FROM asm_test; ---- got the correct value 401
select count(*) from asm_jam_test d where (d.doc.getClobVal()) like '%NTCPO01%'; -- got 1
But i need to find a Specific data from XML (the main goal is to update a value inside XML).
If i try this:
select extract(doc, '/ReceiptDesc/Receipt/ReceiptDtl/item_id/text()').getstringVal() from asm_test
where existsNode(doc,'/ReceiptDesc/Receipt/ReceiptDtl/receipt_nbr') = 1;
got: 509720509740 -- which are the concatenate of 2 Item_ids
when i try to find out the Item_id of specific receipt_nbr i got a NULL response.
select extract(doc, '/ReceiptDesc/Receipt/ReceiptDtl/item_id/text()').getstringVal()
from asm_test
where existsNode(doc,'/ReceiptDesc/Receipt/ReceiptDtl/receipt_nbr') = 1 and
extract(doc,'/ReceiptDesc/Receipt/ReceiptDtl/receipt_nbr/text()').getstringVal() = '6902340';
What i'm doing wrong or which is the best way to get data from XML?
Many thanks in advance

Hi,
Thanks for providing db version and sample data in the first place.
Don't forget to use the {code} tags to preserve formatting.
Also, when posting XML, do not copy/paste directly from your browser as it retains +/- signs and therefore needs extra processing on our side.
select count(*) from asm_jam_test d where (d.doc.getClobVal()) like '%NTCPO01%'; -- got 1No, don't do it like that.
Use existsNode() function in this situation :
SQL> select count(*)
2 from asm_test
3 where existsNode(doc, '/ReceiptDesc/Receipt/ReceiptDtl[user_id="NTCPO01"]') = 1
4 ;
COUNT(*)
         1
when i try to find out the Item_id of specific receipt_nbr i got a NULL response.Yes, that's because this :
extract(doc,'/ReceiptDesc/Receipt/ReceiptDtl/receipt_nbr/text()').getstringVal()returns :
69023406902344So obviously it cannot be equal to '6902340'.
When you have to deal with repeating nodes individually, use XMLTable function to break the structure into relational rows and columns.
The resultset you'll get acts as a virtual table (or inline view) you can then manipulate with SQL operations :
SQL> select x.*
2 from asm_test t
3     , xmltable(
4         '/ReceiptDesc/Receipt/ReceiptDtl'
5         passing t.doc
6         columns item_id     varchar2(15) path 'item_id'
7               , receipt_nbr varchar2(15) path 'receipt_nbr'
8       ) x
9 ;
ITEM_ID         RECEIPT_NBR
509720          6902340
509740          6902344
Now, you can just add a WHERE clause to filter the RECEIPT_NBR you require :
SQL> select x.item_id
2 from asm_test t
3     , xmltable(
4         '/ReceiptDesc/Receipt/ReceiptDtl'
5         passing t.doc
6         columns item_id     varchar2(15) path 'item_id'
7               , receipt_nbr varchar2(15) path 'receipt_nbr'
8       ) x
9 where x.receipt_nbr = '6902340'
10 ;
ITEM_ID
509720
That can also be achieved with EXTRACTVALUE and a single XPath expression (assuming RECEIPT_NBR is unique) :
SQL> select extractvalue(
2           doc
3         , '/ReceiptDesc/Receipt/ReceiptDtl[receipt_nbr="6902340"]/item_id'
4         ) as item_id
5 from asm_test
6 ;
ITEM_ID
509720
