NAME

XML::Saxon::XSLT2 - process XSLT 2.0 using Saxon 9.x.

SYNOPSIS

 use XML::Saxon::XSLT2;
 
 # make sure to open filehandle in right encoding
 open(my $input, '<:encoding(UTF-8)', 'path/to/xml') or die $!;
 open(my $xslt, '<:encoding(UTF-8)', 'path/to/xslt') or die $!;
 
 my $trans  = XML::Saxon::XSLT2->new($xslt, $baseurl);
 my $output = $trans->transform($input);
 print $output;
 
 my $output2 = $trans->transform_document($input);
 my @paragraphs = $output2->getElementsByTagName('p');

DESCRIPTION

This module implements XSLT 1.0 and 2.0 using Saxon 9.x via Inline::Java.

It expects Saxon to be installed in either '/usr/share/java/saxon9he.jar' or '/usr/local/share/java/saxon9he.jar'. Future versions should be more flexible. The saxon9he.jar file can be found at http://saxon.sourceforge.net/ - just dowload the latest Java release of Saxon-HE 9.x, open the Zip archive, extract saxon9he.jar and save it to one of the two directories above.

Import

 use XML::Saxon::XSLT2;

You can include additional parameters which will be passed straight on to Inline::Java, like this:

 use XML::Saxon::XSLT2 EXTRA_JAVA_ARGS => '-Xmx256m';

The import function must be called. If you load this module without importing it, it will not work. (Don't worry, it won't pollute your namespace.)

Constructor

XML::Saxon::XSLT2->new($xslt, [$baseurl])

Creates a new transformation. $xslt may be a string, a file handle or an XML::LibXML::Document. $baseurl is an optional base URL for resolving relative URL references in, for instance, <xsl:import> links. Otherwise, the current directory is assumed to be the base. (For base URIs which are filesystem directories, remember to include the trailing slash.)

Methods

$trans->parameters($key=>$value, $key2=>$value2, ...)

Sets transformation parameters prior to running the transformation.

Each key is a parameter name.

Each value is the parameter value. This may be a scalar, in which case it's treated as an xs:string; a DateTime object, which is treated as an xs:dateTime; a URI object, xs:anyURI; a Math::BigInt, xs:long; or an arrayref where the first element is the type and the second the value. For example:

 $trans->parameters(
    now             => DateTime->now,
    madrid_is_capital_of_spain => [ boolean => 1 ],
    price_of_fish   => [ decimal => '1.99' ],
    my_link         => URI->new('http://example.com/'),
    your_link       => [ uri => 'http://example.net/' ],
 );

The following types are supported via the arrayref notation: float, double, long (alias int, integer), decimal, bool (alias boolean), string, qname, uri, date, datetime. These are case-insensitive.

$trans->transform($doc, [$output_method])

Run a transformation, returning the output as a string.

$doc may be a string, a file handle or an XML::LibXML::Document.

$output_method may be 'xml', 'xhtml', 'html' or 'text' to override the XSLT output method; or 'default' to use the output method specified in the XSLT file. 'default' is the default. In the current release, 'default' is broken. :-(

$trans->transform_document($doc, [$output_method])

As per <transform>, but returns the output as an XML::LibXML::Document.

This method is slower than transform.

$trans->messages

Returns a list of string representations of messages output by <xsl:message> during the last transformation run.

$trans->media_type($default)

Returns the output media type for the transformation.

If the transformation doesn't specify an output type, returns the default.

$trans->doctype_public($default)

Returns the output DOCTYPE public identifier for the transformation.

If the transformation doesn't specify a doctype, returns the default.

$trans->doctype_system($default)

Returns the output DOCTYPE system identifier for the transformation.

If the transformation doesn't specify a doctype, returns the default.

$trans->version($default)

Returns the output XML version for the transformation.

If the transformation doesn't specify a version, returns the default.

$trans->encoding($default)

Returns the output encoding for the transformation.

If the transformation doesn't specify an encoding, returns the default.

BUGS

Please report any bugs to http://rt.cpan.org/.

SEE ALSO

XML::LibXSLT is probably more reliable in terms of easy installation on a variety of platforms, and it allows you to define your own XSLT extension functions. However, the libxslt library that it's based on only supports XSLT 1.0.

This module uses Inline::Java.
