XML::XSLT(3pm) User Contributed Perl Documentation XML::XSLT(3pm) NAME XML::XSLT - A perl module for processing XSLT SYNOPSIS use XML::XSLT; my $xslt = XML::XSLT->new ($xsl, warnings => 1); $xslt->transform ($xmlfile); print $xslt->toString; $xslt->dispose(); DESCRIPTION This module implements the W3C's XSLT specification. The goal is full implementation of this spec, but we have not yet achieved that. However, it already works well. See "XML::XSLT Commands" for the current status of each command. XML::XSLT makes use of XML::DOM and LWP::Simple, while XML::DOM uses XML::Parser. Therefore XML::Parser, XML::DOM and LWP::Simple have to be installed properly for XML::XSLT to run. Specifying Sources The stylesheets and the documents may be passed as filenames, file handles regular strings, string references or DOM-trees. Functions that require sources (e.g. new), will accept either a named parameter or simply the argument. Either of the following are allowed: my $xslt = XML::XSLT->new($xsl); my $xslt = XML::XSLT->new(Source => $xsl); In documentation, the named parameter `Source' is always shown, but it is never required. METHODS new(Source => $xml [, %args]) Returns a new XSLT parser object. Valid flags are: DOMparser_args Hashref of arguments to pass to the XML::DOM::Parser object's parse method. variables Hashref of variables and their values for the stylesheet. base Base of URL for file inclusion. debug Turn on debugging messages. warnings Turn on warning messages. indent Starting amount of indention for debug messages. Defaults to 0. indent_incr Amount to indent each level of debug message. Defaults to 1. open_xml(Source => $xml [, %args]) Gives the XSLT object new XML to process. Returns an XML::DOM object corresponding to the XML. base The base URL to use for opening documents. parser_args Arguments to pase to the parser. open_xsl(Source => $xml, [, %args]) Gives the XSLT object a new stylesheet to use in processing XML. Returns an XML::DOM object corresponding to the stylesheet. Any arguments present are passed to the XML::DOM::Parser. base The base URL to use for opening documents. parser_args Arguments to pase to the parser. process(%variables) Processes the previously loaded XML through the stylesheet using the variables set in the argument. transform(Source => $xml [, %args]) Processes the given XML through the stylesheet. Returns an XML::DOM object corresponding to the transformed XML. Any arguments present are passed to the XML::DOM::Parser. serve(Source => $xml [, %args]) Processes the given XML through the stylesheet. Returns a string containing the result. Example: use XML::XSLT qw(serve); $xslt = XML::XSLT->new($xsl); print $xslt->serve $xml; http_headers If true, then prepends the appropriate HTTP headers (e.g. Content-Type, Content- Length); Defaults to true. xml_declaration If true, then the result contains the appropriate <?xml?> header. Defaults to true. xml_version The version of the XML. Defaults to 1.0. doctype The type of DOCTYPE this document is. Defaults to SYSTEM. xsl_output_method Get or set the <xsl:output method= attribute. Valid arguments are 'html', 'text' and 'xml' toString Returns the result of transforming the XML with the stylesheet as a string. to_dom Returns the result of transforming the XML with the stylesheet as an XML::DOM object. media_type Returns the media type (aka mime type) of the object. dispose Executes the "dispose" method on each XML::DOM object. XML::XSLT Commands xsl:apply-imports no Not supported yet. xsl:apply-templates limited Attribute 'select' is supported to the same extent as xsl:value-of supports path selections. Not supported yet: - attribute 'mode' - xsl:sort and xsl:with-param in content xsl:attribute partially Adds an attribute named to the value of the attribute 'name' and as value the stringified content-template. Not supported yet: - attribute 'namespace' xsl:attribute-set yes Partially xsl:call-template yes Takes attribute 'name' which selects xsl:template's by name. Weak support: - xsl:with-param (select attrib not supported) Not supported yet: - xsl:sort xsl:choose yes Tests sequentially all xsl:whens until one succeeds or until an xsl:otherwise is found. Limited test support, see xsl:when xsl:comment yes Supported. xsl:copy partially xsl:copy-of limited Attribute 'select' functions as well as with xsl:value-of xsl:decimal-format no Not supported yet. xsl:element yes xsl:fallback no Not supported yet. xsl:for-each limited Attribute 'select' functions as well as with xsl:value-of Not supported yet: - xsl:sort in content xsl:if limited Identical to xsl:when, but outside xsl:choose context. xsl:import no Not supported yet. xsl:include yes Takes attribute href, which can be relative-local, absolute-local as well as an URL (preceded by identifier http:). xsl:key no Not supported yet. xsl:message no Not supported yet. xsl:namespace-alias no Not supported yet. xsl:number no Not supported yet. xsl:otherwise yes Supported. xsl:output limited Only the initial xsl:output element is used. The "text" output method is not supported, but shouldn't be difficult to implement. Only the "doctype-public", "doctype-system", "omit-xml-declaration", "method", and "encoding" attributes have any support. xsl:param experimental Synonym for xsl:variable (currently). See xsl:variable for support. xsl:preserve-space no Not supported yet. Whitespace is always preserved. xsl:processing-instruction yes Supported. xsl:sort no Not supported yet. xsl:strip-space no Not supported yet. No whitespace is stripped. xsl:stylesheet limited Minor namespace support: other namespace than 'xsl:' for xsl-commands is allowed if xmlns-attribute is present. xmlns URL is verified. Other attributes are ignored. xsl:template limited Attribute 'name' and 'match' are supported to minor extend. ('name' must match exactly and 'match' must match with full path or no path) Not supported yet: - attributes 'priority' and 'mode' xsl:text yes Supported. xsl:transform limited Synonym for xsl:stylesheet xsl:value-of limited Inserts attribute or element values. Limited support: <xsl:value-of select="."/> <xsl:value-of select="/root-elem"/> <xsl:value-of select="elem"/> <xsl:value-of select="//elem"/> <xsl:value-of select="elem[n]"/> <xsl:value-of select="//elem[n]"/> <xsl:value-of select="@attr"/> <xsl:value-of select="text()"/> <xsl:value-of select="processing-instruction()"/> <xsl:value-of select="comment()"/> and combinations of these. Not supported yet: - attribute 'disable-output-escaping' xsl:variable partial or from literal text in the stylesheet. xsl:when limited Only inside xsl:choose. Limited test support: <xsl:when test="@attr='value'"> <xsl:when test="elem='value'"> <xsl:when test="path/[@attr='value']"> <xsl:when test="path/[elem='value']"> <xsl:when test="path"> path is supported to the same extend as with xsl:value-of xsl:with-param experimental It is currently not functioning. (or is it?) SUPPORT General information, bug reporting tools, the latest version, mailing lists, etc. can be found at the XML::XSLT homepage: http://xmlxslt.sourceforge.net/ DEPRECATIONS Methods and interfaces from previous versions that are not documented in this version are deprecated. Each of these deprecations can still be used but will produce a warning when the deprecation is first used. You can use the old interfaces without warnings by passing "new()" the flag "use_deprecated". Example: $parser = XML::XSLT->new($xsl, "FILE", use_deprecated => 1); The deprecated methods will disappear by the time a 1.0 release is made. The deprecated methods are : output_string use toString instead result_string use toString instead output use toString instead result use toString instead result_mime_type use media_type instead output_mime_type use media_type instead result_tree use to_dom instead output_tree use to_dom instead transform_document use transform instead process_project use process instead open_project use "Source" argument to new() and transform instead. print_output use serve() instead. BUGS Yes. HISTORY Geert Josten and Egon Willighagen developed and maintained XML::XSLT up to version 0.22. At that point, Mark Hershberger started moving the project to Sourceforge and began working on it with Bron Gondwana. LICENCE Copyright (c) 1999 Geert Josten & Egon Willighagen. All Rights Reserved.
