saxonq — command line XQuery processor

Synopsis

saxonq [OPTION...] QUERYFILE [NAME=VALUE...]

Description

This manual page documents briefly the saxonq command. This page was written for the Debian(TM) distribution because the original program does not have a manual page. Still, it has HTML documentation which is shipped in the "saxon-manual" package.

saxonq is a command line wrapper around the Saxon-B XSLT and XQuery processor. Using saxonq you can evaluate XQuery queries directly from the command line. Internally, saxonq is a wrapper around the Java class net.sf.saxon.Query implemented by Saxon-B.

saxonq should be invoked passing a (required) filename containing the XQuery query to be evaluated; the special filename "-" can be given to require reading the query from standard input.

Before the query filename a list of options can be given, see below.

Parameters

At the end of the command line, a list of parameters can be given. Parameters are passed using the syntax NAME=VALUE, to specify parameters´ names and values.

A parameter name prefixed with "+" (plus sign) will be interpreted as a filesystem path parameter If the path points to a single file, that file will be parsed as XML and its document node will be passed as the parameter value. If the path points to a directory, all directly contained files will be parsed as XML files, and the sequence of their document nodes will be passed as the parameter value.

A parameter name prefixed with "!" (exclamation mark) will be interpted as a output/serialization parameter. See the specifications of XQuery and XSLT 2.0 for more information on output/serialization parameters.

To pass parameters belonging to the non-null namespace, the syntax {uri}localname=value is provided.

Parameters will be visible as external variables during query evaluation, provided they have been declared in the query prolog. See the XQuery specification for more information on variables and their declarations.

Options

A summary of supported options is included below. Options can be passed in any order.

We first report the options which are shared by saxonq and saxon, then those specific to saxonq (or which have a different semantics).

Some options are flagged as "Saxon-SA only", such options work only if Saxon-SA is installed. Note that Saxon-SA is a commercial product, as such it is not available in Debian.

Common options

-cr:classname

Specify a class to be used for processing collection URIs passed to the collection() function. The class must implement net.sf.saxon.CollectionURIResolver.

-dtd: {[on] | [off]}

Enable or disable DTD validation. Default: off.

-expand: {[on] | [off]}

When validation is enabled, expand default values in validated documents. This option enables or disables such an expansion. Default: on.

-explain [:filename]

Display an execution plan; the output is in XML format. If filename is not given it will be displayed on standard output.

-ext: {[on] | [off]}

Enable or disable the ability to invoke external Java functions from query files and stylesheets. Beware that enabling them is a potential security risk when processing untrusted files. Default: off.

-l: {[on] | [off]}

Keep (when on) or throw away (when off) line numbers in tress corresponding to source documents. When kept, line numbers can be accessed using the function saxon:line-number(). Default: off.

-outval: {[recover] | [fatal]}

When validation is required, set whether validation errors are fatal (when "fatal" is passed) or if they only trigger warnings (when "recover" is). Default: fatal.

-p: {[on] | [off]}

Enable or disable usage of the PTreeURIResolver. Saxon-SA only.

-r:classname

Specify a class to be used for resolving all URIs.

-repeat:N

Repeat the transformation N times. For benchmarking purposes.

-sa

Perform Schema-aware processing. Saxon-SA only.

-strip: {[all] | [none] | [ignorable]}

Specify whitespace stripping policy for source documents: strip all of them ("all"), strip none of them ("none"), strip ignorable whitespace only ("ignorable"). Default: none.

-t

Display version, timing, and other debugging information on standard error.

-tree: {[tiny] | [linked]}

Select the implementation of the internal tree model: tiny tree model ("tiny") or linked tree model ("linked"). See the Saxon documentation for more information on the internal tree model. Default: tiny.

-T [:classname]

Trace various aspect of the processing; an optional class name can be given to specify a user-chosen tracer. The class must implement net.sf.saxon.trace.TraceListener. The default is a system supplied tracer. This option implies -l.

-TJ

Enable tracing of external Java method invocation. See -ext.

-u

Force interpretation of source document names as URI. By default they are considered to be file names, unless they start with "file:" or "http:".

-val: {[strict] | [lax]}

When validation is enabled, choose among "strict" or "lax" validation. Saxon-SA only.

-x:classname

Specify a class to be used as SAX parser for input documents. The class must implement either org.xml.sax.Parser or org.xml.sax.XMLReader.

-xi

Apply XInclude processing to all input documents.

-xmlversion: {[1.0] | [1.1]}

Choose the XML version for processing input documents. "1.1" must be specified to process XML 1.1 and Namespaces 1.1 constructs. Default: 1.0.

-?

Display a help message and exit.

Options specific to saxonq

-mr:classname

Use the specifed class as a ModuleURIResolver to resolve query module URIs. The class must implement net.sf.saxon.query.ModuleURIResolver.

-o:filename

Send the query output to the specified filename. If not specified the output will be sent to standard output. See also -wrap.

-pipe: {[push] | [pull]}

Internally, execute query in push or pull mode. Mainly for testing purposes. Push mode is usually faster when intermediate tree are constructed in memory. Default: push.

-projection: {[on] | [off]}

Enable or disable document projection, i.e. the ability to throw away tree parts which will not be accessed by a query. Saxon-SA only.

-s: {[file] | [URI]}

Read document input from the specified filename ("-" can be given to read from standard input). The read document will be available to the query as the context node. -u affects how filename is interpreted.

-wrap: {[on] | [off]}

Enable or disable wrapping of query result in a XML structure which makes explicit the kind of each output node or atomic value. For example free-standing attributes will be wrapped in an explicit XML element stating that they are attributes. When this is off, the query output will be wrapped only using a document node; in such a setting is possible that output parts, such as free-standing attributes, can´t be serialized. Default: off.
