Difficulty getting Saxon mode in XQuery instead of XSLT

Question

I find it difficult to work with XQuery. I downloaded Saxon-HE 9.2. He seems to want to work only with XSLT.

When I type:

java -jar saxon9he.jar 

I am returning usage information for XSLT. When I use the command syntax for XQuery, it does not recognize parameters (e.g. -q) and provides information about using XSLT.

Here are some command line interactions:

 >java -jar saxon9he.jar No source file name Saxon-HE 9.2.0.6J from Saxonica Usage: see http://www.saxonica.com/documentation/using-xsl/commandline.html Options: -a Use xml-stylesheet PI, not -xsl argument -c:filename Use compiled stylesheet from file -config:filename Use configuration file -cr:classname Use collection URI resolver class -dtd:on|off Validate using DTD -expand:on|off Expand defaults defined in schema/DTD -explain[:filename] Display compiled expression tree -ext:on|off Allow|Disallow external Java functions -im:modename Initial mode -ief:class;class;...

Could not find the main class: net.sf.saxon.Query. Program will exit. 

Perhaps I will make some kind of stupid mistake. Do you know what it could be?

UPDATE 1 This command does not work:

 >java -jar saxon9he.jar net.sf.saxon.Query q:"..\w3xQueryTut.xq" Source file net.sf.saxon.Query does not exist 

UPDATE 2 This command works better:

 >dir 03/28/2010 16:07 <DIR> . 03/28/2010 16:07 <DIR> .. 03/27/2010 13:37 849 books.xml 03/27/2010 13:32 <DIR> doc 03/27/2010 13:32 <DIR> notices 03/27/2010 13:32 5,473,874 saxon9he.jar 03/27/2010 13:38 37 w3xQueryTut.xq >java -cp saxon9he.jar net.sf.saxon.Query q:"w3xQueryTut.xq" java.io.FileNotFoundException: q:w3xQueryTut.xq (The system cannot find the path specified) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(Unknown Source) at java.io.FileInputStream.<init>(Unknown Source) at net.sf.saxon.Query.compileQuery(Query.java:885) at net.sf.saxon.Query.doQuery(Query.java:183) at net.sf.saxon.Query.main(Query.java:89) Fatal error during query: java.io.FileNotFoundException: q:w3xQueryTut.xq (The s ystem cannot find the path specified)

Answer 1

I have no problem with this command line usage :

java -cp C:\xml\Parsers\Saxon\HE-9-2-0-6\saxon9he.jar net.sf.saxon.Query
-q:"C:\Program Files\Oxygen XML Editor 11\samples\xquery\Books\authors.xquery"

Answer 2

When you use " java -jar saxon9he.jar ", you ask Java to call the default entry point in the JAR file, which is net.sf.saxon.Transform . To enter at a specific entry point, for example net.sf.saxon.Query , you need to use the form " java -cp saxon9he.jar net.sf.saxon.Query ".

• pre preparations
• Download Saxon: You must first download the Saxon package at http://sourceforge.net/projects/saxon/ and unzip it at some directory like D:\Program Files\SaxonHE9-5-0-1J .
• Get the source code: If you want to get the source code, download it at http://nchc.dl.sourceforge.net/project/saxon/Saxon-HE/9.3/saxon-resources9-3.zip before unpacking it into the directory SaxonHE9-5-0-1J;
• Build workstation: prepare a workstation for you: in SaxonHE9-5-0-1J\iexercise , where you can put your * .xq files and their results; You can also create a directory called icache to store your caches;

• Let Java know where to find the interpreter: For it to work well for Xquery statements, you need to add the main package for interpreting it in Windows: open a command prompt and go to SaxonHE9-5-0-1J and run saxon9he.jar in jdk1.7.0\lib after copying jdk1.7.0\lib :

  set classpath =.;% java_home% \ lib \ saxon9he.jar

• Check if this is known: Thus, you can usually run xquery scripts immediately after step 4. If you are not sure about this, run it: java net.sf.saxon.Query 2. Prepare your first run

• Create a file (for example, with the name test.xq) with the affixes .xq, .xquery or .xqy in iexercise, its contents are displayed below:

  doc ("catalog.xml") / catalog / product [@dept = "ACC"]

• Copy the pre-made catalog.xml file to. /.

• Run java net.sf.saxon.Query -q:test.xq -o:result.xml first argument tells the interpreter to compile the xquery file, which is your work in step 1.4, -q: filename is the file that will be compiled with xquery instructions, and the third shows where to put the result; if not specified, will be displayed on standard output.

Directory File:

 <catalog> <product dept="WMN"> <number>557</number> <name language="en">Fleece Pullover</name> <colorChoices>navy black</colorChoices> </product> <product dept="ACC"> <number>563</number> <name language="en">Floppy Sun Hat</name> </product> <product dept="ACC"> <number>433</number> <name language="en">Deluxe Travel Bag</name> </product> <product dept="MEN"> <number>784</number> <name language="en">Cotton Dress Shirt</name> <colorChoices>white green</colorChoices> <desc>Our <i>favorite</i> shirt!</desc> </product> </catalog> 

Answer 4

Please note that the saxon documentation does not say

 java -jar saxon9he.jar net.sf.saxon.Query -q:myQuery.xql 

(this is not a jar executable, and you don't need -q at all if the last xql file) will therefore work

 java net.sf.saxon.Query myQuery.xql 

or

 java -cp C:\downloads\saxon\saxon9he.jar net.sf.saxon.Query myQuery.xql
