XPATH with CL_XSLT_PROCESSOR- set_expression( ... )

Hi all,
I have a problem by using the method cl_xslt_processor->set_expression( expression = ... nsdeclarations = ... ). I want to use this method to get some nodes by using Xpath.
My problem is the parameter 'nsdeclarations' which should be filled like 'prefix1 URI1 prefix2 URI2 ...'. But my xml document has no prefix. It looks like
<ROOT xmlns="http://uri">....</ROOT>
After getting a node collection I create a iterator und try to get the first element ( lr_element ?= lr_iterator->get_next( ). )
But lr_element is always initial. I tried to call the method without the parameter 'nsdeclarations' (is optional) but it didn't work, as well as passing only the uri.
If I put a prefix into my xml and my namespace parameter it works.
Does anybody have an idea what has to be passed in my case (no namespace prefix)?
Thanks in advance.
Best regards
Guenter

Hi,
You have to map default namespance to your own prefix and the use it in the XPath.
See example where I declare 'my' prefix
DATA l_xslt TYPE REF TO cl_xslt_processor.
DATA: nodes TYPE REF TO if_ixml_node_collection.
CREATE OBJECT l_xslt TYPE cl_xslt_processor.
l_xslt->set_source_string(
 '<?xml version="1.0" encoding="ISO-8859-1"?>' &
 '<a xmlns="http://uri.com">' &
 '<foo>bar</foo>' &
 '</a>' ).
l_xslt->set_expression(
expression = 'my:a/my:foo'
nsdeclarations = 'my http://uri.com'
l_xslt->run( '' ).
nodes = l_xslt->get_nodes( ).

Is there any possibility to combine XPath with SAX in Java?

HI Gentlemen,
I have an XML instance to parse. One solution works with XPath and Document builder. However, the tree in memory is too big so that I can not build it in my storage (8 GB). Does anyone of you know a method where I use an XPath expression (Java) to select a node but with a better parser (e g SAX) which is not so space hungry? Direct access of nodes is obligatory.
Thanks, kind regards from
Miklos HERBOLY

As SAX parsers do not build a DOM structure and XPath requires a DOM structure to select elements from, XPath is not usable with SAX, but some analysers support setting the XPath expressions to analyse before invoking the SAX parser and provide the result for XPath expressions.

Building XPath with the XML having the Namespace using PL SQL

While trying to build the path of each node, when the XML has no namespace in it , the below code works fine providing the result
1~/
2~/person/
3~/person/age/
4~/person/homecity/
5~/person/name/
6~/person/homecity/lat/
7~/person/homecity/name/
8~/person/homecity/long/
But when the xml is changed to

<age>37</age>
<homecity>
 <name>London</name>
 <lat>123.000</lat>
 <long>0.00</long>
</homecity>
</person>"
The result on executing the below code is resulting into only into below result
1~/
2~/person/
In the XML provided above, XML name space is not constant and it may vary for every XML. My requirement is to parse the complete XML, where i can read the XML with namespace and get the result as mentioned below
1~/

Hi,
Thanks for the reply.
Please find the details :
1) What's your database version ?

The XML provided was for sample XML.
The practical use being ,I wanted to parse the SEPA messages using the below code snippet dynamically.

The idea was to :
1). Map the Column Names for the XPath built using the previous code.
2). Build the Select statement shown above dynamically based on the Xpath built in the previous code using a PLSQL block, and to process the data by doing a bulk collect on the XML.
The above XML may contain multiple <FIToFICstmrCdtTrf></FIToFICstmrCdtTrf> nodes.
Since the name space in the XML varies for each version of the SEPA messages , i need to get the names spaces ALSO to be picked up dynamically and parse the XML data based on the select statement as shown above.
Could you please guide me with
1). Is the approach taken appropriate?
2). Any alternative approach should be looked for ?
3). How to extract the name spaces available in the XML?
Thanks.

XPath with XML Schema

Is there any way of finding out the namespace prefix if there is one, from a DOMParser instance or a XMLDocument instance?
I have a DOMParser instance and I don't know whether there is a namespace specification in it. If there is, I need to know what it is so I can update my XPath expressions to use the appropriate prefix.
I have tried the XMLDocument.getNamespace function but it doesn't seem to be implemented (or it is depricated).
Any help would be greatly appreciated.

You're right on track with the namespaces hunch.
XPath 1.0 does not provide the ability to search on the default namespace.
That is, even if you document looks like this:<foo xmlns="urn:bar"/>you cannot use any compliant XPath 1.0 implementation to find the <foo> element with the pattern /foo, since in XPath 1.0 /foo finds the <foo> element that is the child of the root with a null namespace URI.
In the example above, the namespace uri of the <foo> element is urn:bar, so in particular it's not null.
With XPath 1.0, you need to specifically qualify the foo element with a namespace prefix that is bound to the same namespace URI as your default namespace.
So, your XPath would need to look like /xxx:foo where xxx is an arbitrary namespace prefix associated with the urn:bar namespace URI.
The selectNodes, selectSingleNode, and valueOf methods all have an overloading which takes an instance of the oracle.xml.parser.v2.NSResolver interface as the 2nd argument. This argument is used to resolve what namespace prefixes found in the XPath search string map to.
To implement the NSResolver interface, you need only implement a single method:
String resolveNamespacePrefix(String prefix);
In the example above, this method would return the string "urn:bar" when passed the prefix string "xxx" so that the XPath of /xxx:foo would match the <foo> element with urn:bar namespace uri in the example document above.

Problems using XPath with underscore (10g)

I'm trying to extract an attribute called OrderID from XML, normally I'd expect this to work with //Node/@OrderID, but instead I get "LPX-00601: Invalid token in:... " complaining about the underscore in the attribute name.
Is there anyway to get around this (apart from renaming the attribute)?
Thanks

What I tried to say is that you could try to escape it...
I am not sure (and I don't have the energy to look it up), but if an underscore is correct regarding XPath syntax then it should be handled as a bug and you should file a service request for it on http://metalink.oracle.com.

How to use XPath with XMLBean?

Hi all,
I'm using xmlbean for a new project now, and everything was great until I tried
to use a XPath selection.
I got a "java.lang.UnsupportedOperationException: This operation requires xqrl.jar"
exception, but I could not find this jar anywhere.
I'm using the stand alone version of XMLBena. This is a small project and there
is no need for an App Server, therefore no full WebLogic 8.1
Any ideas?
Thanks,
Silvio

Hello Silvio -- Are you working with XMLBeans as downloaded from Apache?
XPath support in the standalone implementation of XMLBeans is limited to
simple expressions. The more sophisticated support available via xqrl.jar is
included with XMLBeans as it ships with WebLogic Platform 8.1.

Use of Xpather with OATS.

We have been using Selenium.
Now we are learning OATS. Can we use the "XPather',FireBug with OATS.
I assume we can use the isTextPresent, asserEquals etc with OATS tool.
Is this correct.
Regards

Thanks for the reply Alex.
I would like to know whether or not we can use Firebug,XPather tool (these attach to Firefox browser only). These are not related to OpenScript directly, though, the IDE/Interface is eclipse, it seems.

How to use XPath with Namespaces in the xml ?

Hi all,
I need to reference a certain Node in a Document using XPath notation.
The problem is the the XML Document contains Namespaces inside it
f.e.
<xn:SubNetwork id="JRANM">
 <xn:VsDataContainer id="1">
 <xn:vsDataType>vsDataAreas</xn:vsDataType>
 </xn:VsDataContainer>
</xn:SubNetwork >Using DOMXPath (from weblogic.xml.xpath)
DOMXPath xPath = new DOMXPath("xn:SubNetwork/*");
Set nodeset = xPath.evaluateAsNodeset(this.xmlRootElement);When I Iterate through the Set I can see it's empty.
(On the other hand without namespaces everything is fine.)
So how can I reference a Node that contains a namespace in it ?
Thanks a lot

Extractvalue() has a third parameter we can use to declare namespace mappings :

14 , 'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"'
15 )
16 from sample_data
17 ;
EXTRACTVALUE(DOC,'/EXTENDEDDAT
true
If you're on 11.2.0.2 and up, extractvalue() is deprecated.
One should use XMLCast/XMLQuery instead :
SQL> with sample_data as (
2 select xmltype('<?xml version="1.0"?>
3 <ExtendedData>
4 <Parameter name="CALLHOLD"><BooleanValue>true</BooleanValue></Parameter>
5 <Parameter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="BARRING_PASSWORD" xsi:nil="true"/>
6 <Parameter name="ALLCF"><BooleanValue>true</BooleanValue></Parameter>
7 <Parameter name="RealProv"><BooleanValue>false</BooleanValue></Parameter>
8 </ExtendedData>') doc
9 from dual
10 )
11 select xmlcast(
12 xmlquery('/ExtendedData/Parameter[@name="BARRING_PASSWORD"]/@xsi:nil'
13 passing doc
14 returning content
15 ) as varchar2(5)
16 )
17 from sample_data
18 ;
XMLCAST(XMLQUERY('/EXTENDEDDAT
true
Note : the xsi prefix is predefined when using Oracle XQuery, so in this case we don't have to declare it explicitly.

Xpath with another xpath between single quotes

Hello,
Im using an xpath expression to find a node in a xml variable. In this xpath I need to equal the text part of the resolved node to the value returned from the xpath from another xml variable. The value returned from the second xpath needs to be between single quotes in the first xpath, but it is not working. I already tried this:
/path_to_xml1/root_node/node[text = '/path_to_xml2/root_node/node']
string(/path_to_xml1/root_node/node[text = '/path_to_xml2/root_node/node'])
string(/path_to_xml1/root_node/node[text = 'string(/path_to_xml2/root_node/node')])
thank you

When you say : "...I need to equal the text part of the resolved node", are you talking about a text attribute of the node or just the value of that node?
If it's just the value of the node then you should just use /path_to_xml1/root_node/node /path_to_xml2/root_node/node

Xpath with unknown namespace prefix

Given XML that looks like this
 <nnn:XXX>
 <mmm:YYY>value</mmm:YYY>
 </nnn:XXX>
And in the above the 'mmm' can vary but the 'YYY' doesn't.
Can one construct an XPath expression that explicity returns the node-set for the inner element block using 'YYY'?
I am not looking for a first node or indexed solution but rather one that explicitly uses 'YYY' and not 'mmm' in some way.
I tried several variations (guesses) using the function Contains but that did nothing but produce syntax errors.

The namespace prefix is meaningless, it's only the namespace URI that is significant, so there's no XPath way of searching given a namespace prefix. But fortunately you have the opposite problem, you don't care about the namespace at all. The XPath function local-name() returns the local part of the name of a node, in your example the "YYY" part of the element name.

Using XPath with the XML DOM

I have just started to use the XML DOM API. One thing I cannot see yet is an easy way to use XPath to get the value of an element.
What I would like to do is pass an XPath expression like this:
\EDIFACT\ORDERS\NAD[2]\NAD01\NAD0102
into a method, and get the value of the element returned to me.
Does anybody know if there is a method of one of the DOM interfaces that would provide that kind of functionality, or am I going to have to traverse the nodes of the DOM tree manually to do this?
BR,
Tony.

Hi Tony,
I read your posted question - I have the same problem.
I think that the method find_from_path_ns (or find_from_path) is the only "xpath"-like way to get a value.
BUT the syntax is very limited so you cannot use all good features of xpath
To traverse the nodes manually is (in my problem) unpractible - the xml-structures are different and it's horrible to traverse the tree.
I need xpaths like ' //x/y[3]/z[a='MS']' . I know, the performance is not very good but for small XML-messages fast enough
Do you have any solutions?
regards
Wolfgang Hummel

Reading more than one value with XPath and java 1.5

Hello, I'm using XPath with Java 1.5 and I've some problems.
I do these things:
File xmlDocument = new File("c:/test.xml");
InputSource inputSource = new InputSource(new FileInputStream(xmlDocument));
XPathFactory factory = XPathFactory.newInstance();
XPath xPath = factory.newXPath();
int replication = Integer.parseInt(xPath.evaluate("/simulation/setup/replication", inputSource));
System.out.println(replication); // THIS WORKS!
warmuptime = Integer.parseInt(xPath.evaluate("/simulation/setup/warmuptime", inputSource));
System.out.println(warmuptime); // THIS DON'T WORK: javax.xml.xpath.XPathExpressionException
As I had written in the comments, the first time I call ".evaluate", it works, the second time it raises an exception.
The Xml is correct! The string "/simulation/setup/warmuptime" is correct!
I tryed to place a:
xPath.reset()
between the two "evaluate", but still doesn't work.
Can you give me an help? or suggest me an url where these things are explained in a simple way?
I just need to get some data from an XML file and XPath seems to be the quickest and easiest way.
Thanks for the help.

Are all the files in one directory? If so you can make a File object of the directory, get an array of all files in that directory (File has a method to do this). Then loop over your array and call a method that reads the File that you pass as a parameter.

XSLT Processor, set_expression

hello,
in the last few days i´ve posted several questions about xslt, xslt processor, ixml etc., but nobody could give me an answer. i think all my attempts to solve my problem gone to the wrong path.
now, this will be my last question to this topic.
is it possible to use xsl functions such like concat, count, etc. with the set_expression method in class cl_xslt_processor (see below).
it tested it with different xpath-expression.
i guess it is not possible. only logical path expression seems to work. when i call method "get_nodes" the result is empty, also the result of method "output_string" and "output_stream".
okay, i see why get_nodes do not return a ixml_node_collection, but i hoped a result would be return by an other method or attribute.
i would be very happy, if someone could approve my attempts or knows a workaround.
kind regards
sebastian

I come to the conclusion that it´s not possible to use any xsl-function such as concat, substring etc.

XPATH with CL_XSLT_PROCESSOR- set_expression( ... )
