XML::XSLT - A perl module for processing XSLT use XML::XSLT; my $xslt = XML::XSLT->new ($xsl, warnings => 1); $xslt->transform ($xmlfile) print $xslt->asString $xslt->dispose (); 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. 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.

new(Source => $xml [, %args])
Returns a new XSLT parser object. Valid flags are: Hashref of arguments to pass to the XML::DOM::Parser object's parse method. Hashref of variables and their values for the stylesheet. Base of URL for file inclusion. Turn on debugging messages. Turn on warning messages. Starting amount of indention for debug messages. Defaults to 0. 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. The base URL to use for opening documents. 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. The base URL to use for opening documents. 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 containg the result. Example: use XML::XSLT qw(serve); $xslt = XML::XSLT->new($xsl); print $xslt->serve $xml; If true, then prepends the appropriate HTTP headers (e.g. Content-Type, Content-Length); Defaults to true. If true, then the result contains the appropriate <?xml?> header. Defaults to true. The version of the XML. Defaults to 1.0. The type of DOCTYPE this document is. Defaults to SYSTEM.

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.

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		no
Not supported yet.

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
Not supported yet: - attribute 'use-attribute-sets'

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			experimental
Very limited. It should be possible to define a variable and use it with &lt;xsl:value select="$varname" /&gt; within the same template.

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?) General information, bug reporting tools, the latest version, mailing lists, etc. can be found at the XML::XSLT homepage: http://xmlxslt.sourceforge.net/ 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 deprecations will disappear by the time a 1.0 release is made. Yes. 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. Copyright (c) 1999 Geert Josten & Egon Willighagen. All Rights Reserverd.
