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.

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.
