[saxon] Using Collections

[Sweta Kedia <swetakedia@gm...>]

Hi,
I read about collections in Saxonica documentation. It mentions about
catalog files.

I wanted to know whether I can use this catalog file for listing all the
directories and xml files which are to be used in Xquery expressions.
I want to make separate xquery files which will be called from java
application using XQJ implementation.
How can I reference the files mentioned in catalog files in my xquery
expressions?
Please explain.

Also I have a question about properties file.
I made a property file having:
ClassName = net.sf.saxon.xqj.SaxonXQDataSource
BaseUri = C:/Users/A/Documents/Sweta/users

I am using this file for creating my connection.
Properties p = new Properties();
                p.load(new
FileInputStream(System.getProperty("user.dir")+"/temp/xqj.properties"));


                String xqdsClassName = p.getProperty("ClassName");
                Class xqdsClass = Class.forName(xqdsClassName);


                SaxonXQDataSource dataSource = (SaxonXQDataSource)
xqdsClass.newInstance();


 I wanted to know whether the  BaseUri I am giving in the property file will
be referenced   by xquery Expressions. If yes, how can I make a reference to
this Base Uri in my xquery expression to use all the xml files and sub
directories under this Uri.



Thanks and Regards

Sweta

	I read about collections in Saxonica documentation. It mentions

	I wanted to know whether I can use this catalog file for listing all
the  directories and xml files which are to be used in Xquery expressions.
	I want to make separate xquery files which will be called from java
application using XQJ implementation.
	How can I reference the files mentioned in catalog files in my
xquery expressions?
	Please explain.

MHK>I'm sorry, I don't really understand what you are trying to achieve. If
you want to make multiple xquery files, what will they look like and how
will they differ from each other?

	
	Also I have a question about properties file.

MHK>It's really better to raise one question at a time. Otherwise the
threads can become hopelessly entangled.

	I made a property file having:
	ClassName = net.sf.saxon.xqj.SaxonXQDataSource
	BaseUri = C:/Users/A/Documents/Sweta/users
	
	I am using this file for creating my connection.
	Properties p = new Properties();
	                p.load(new
FileInputStream(System.getProperty("user.dir")+"/temp/xqj.properties"));
	
	               
	                String xqdsClassName = p.getProperty("ClassName");
	                Class xqdsClass = Class.forName(xqdsClassName);
	
	               
	                SaxonXQDataSource dataSource = (SaxonXQDataSource)
xqdsClass.newInstance();
	                
	
	 I wanted to know whether the  BaseUri I am giving in the property
file will be referenced   by xquery Expressions. 

MHK>No, the query processor knows nothing about your property file.


If yes, how can I make a reference to this Base Uri in my xquery expression
to use all the xml files and sub directories under this Uri.

MHK>You create an XQConnection and in the XQConnection you can call
setStaticContext(). The XQStaticContext object has a setBaseURI() method.
This is where you need to set the base URI.

MHK>By the way, the base URI should be a URI, not a filename. The example
you gave was a filename.
