Free xml xslt software for linux

XMLStarlet is a set of command line utilities (tools) which can be used to transform, query, validate, and edit XML documents and files using simple set of shell commands in similar way it is done for plain text files using UNIX grep, sed, awk, diff, patch, join, etc commands.
This set of command line utilities can be used by those who deal with many XML documents on UNIX shell command prompt as well as for automated XML processing with shell scripts.
Main features:
- Check or validate XML files (simple well-formedness check, DTD, XSD, RelaxNG)
- Calculate values of XPath expressions on XML files (such as running sums, etc)
- Search XML files for matches to given XPath expressions
- Apply XSLT stylesheets to XML documents (including EXSLT support, and passing parameters to stylesheets)
- Query XML documents (ex. query for value of some elements of attributes, sorting, etc)
- Modify or edit XML documents (ex. delete some elements)
- Format or "beautify" XML documents (as changing indentation, etc)
- Fetch XML documents using http:// or ftp:// URLs
- Browse tree structure of XML documents (in similar way to ls command for directories)
- Include one XML document into another using XInclude
- XML c14n canonicalization
- Escape/unescape special XML characters in input text
- Print directory as XML document
- Convert XML into PYX format (based on ESIS - ISO 8879), and vice versa
XMLStarlet command line utility is written in C and uses libxml2 and libxslt from http://xmlsoft.org/.
Implementation of extensive choice of options for XMLStarlet utility was only possible because of rich feature set of libxml2 and libxslt (many thanks to the developers of those libraries for great work).
diff and patch options are not currently implemented. Other features need some work too. Please, send an email to the project administrator (see http://sourceforge.net/projects/xmlstar/) if you wish to help.
XMLStarlet is linked statically to both libxml2 and libxslt, so generally all you need to process XML documents is one executable file. To run XmlStarlet utility you can simple type xml on command line and see list of options available.
XMLStarlet is open source freeware under MIT license which allows free use and distribution for both commercial and non-commercial projects.

mod_xml is an XML applications development environment for Apache 2.0. mod_xmls primary purpose is to provide a powerful, full-featured opensource platform for Webservices and XML applications.
Written in C (and possibly C++, depending on the XML library used) and fully integrated into Apache, it should present a leaner, meaner system and a far lower overhead than the heavyweight alternatives that have traditionally dominated this market.
It comprises three main components:
- Main Handler: SAX and DOM APIs for applications development
- Input filter: convert request data to XML, with additional options to encapsulate HTTP headers (XMTP) and CGI vars.
- XSLT output filter for dynamic publishing.
XML Platform
mod_xml requires an XML implementation, to support the required XML and XSLT technologies. The XML implementations currently provided are:
- apache, using Xerces-C and Xalan-C
- gnome, using libxml2 and libxslt
So you will need to have either Xalan/Xerces or libxml2/libxslt installed before you can build mod_xml. Applications using the SAX or DOM should use the same XML libraries that were used to build the module. Applications using only XSLT can use any XML implementation.
Other XML implementations, such as expat+sablot, may be supported as and when resources permit.

Pod::XML is a Perl module to convert POD to XML.

SYNOPSIS

use Pod::XML;
my $parser = Pod::XML->new();
$parser->parse_from_file("foo.pod");

This module uses Pod::Parser to parse POD and generates XML from the resulting parse stream. It uses its own format, described below.

XML::DOM::Lite is a Lite Pure Perl XML DOM Parser Kit.

SYNOPSIS

# Parser
use XML::DOM::Lite qw(Parser :constants);

$parser = Parser->new( %options );
$doc = Parser->parse($xmlstr);
$doc = Parser->parseFile(/path/to/file.xml);

# strip whitespace (can be about 30% faster)
$doc = Parser->parse($xml, whitespace => strip);


# All Nodes
$copy = $node->cloneNode($deep);
$nodeType = $node->nodeType;
$parent = $node->parentNode;
$name = $node->nodeName;
$xmlstr = $node->xml;
$owner = $node->ownerDocument;

# Element Nodes
$first = $node->firstChild;
$last = $node->lastChild;
$tag = $node->tagName;
$prev = $node->nextSibling;
$next = $node->previousSibling;

$node->setAttribute("foo", $bar);
$foo = $node->getAttribute("foo");
foreach my $attr (@{$node->attributes}) { # attributes as nodelist
# ... do stuff
}
$node->attributes->{foo} = "bar"; # or as hashref (overload)

$liveNodeList = $node->getElementsByTagName("child"); # deep

$node->insertBefore($newchild, $refchild);
$node->replaceChild($newchild, $refchild);


# Text Nodes
$nodeValue = $node->nodeValue;
$node->nodeValue("new text value");

# Processing Instruction Nodes
# CDATA Nodes
# Comments
$data = $node->nodeValue;

# NodeList
$item = $nodeList->item(42);
$index = $nodeList->nodeIndex($node);
$nlist->insertNode($newNode, $index);
$removed = $nlist->removeNode($node);
$length = $nlist->length; # OR scalar(@$nodeList)


# NodeIterator and NodeFilter
use XML::DOM::Lite qw(NodeIterator :constants);

$niter = NodeIterator->new($rootnode, SHOW_ELEMENT, {
acceptNode => sub {
my $n = shift;
if ($n->tagName eq wantme) {
return FILTER_ACCEPT;
} elsif ($n->tagName eq skipme) {
return FILTER_SKIP;
} else {
return FILTER_REJECT;
}
}
);
while (my $n = $niter->nextNode) {
# do stuff
}

# XSLT
use XML::DOM::Lite qw(Parser XSLT);
$parser = Parser->new( whitespace => strip );
$xsldoc = $parser->parse($xsl);
$xmldoc = $parser->parse($xml);
$output = XSLT->process($xmldoc, $xsldoc);


# XPath
use XML::DOM::Lite qw(XPath);
$result = XPath->evaluate(/path/to/*[@attr="value"], $contextNode);


# Document
$rootnode = $doc->documentElement;
$nodeWithId = $doc->getElementById("my_node_id");
$textnode = $doc->createTextNode("some text string");
$element = $doc->createElement("myTagName");
$docfrag = $doc->createDocumentFragment();
$xmlstr = $doc->xml;
$nlist = $doc->selectNodes(/xpath/expression);
$node = $doc->selectSingleNode(/xpath/expression);


# Serializer
use XML::DOM::Lite qw(Serializer);

$serializer = Serializer->new;
$xmlout = $serializer->serializeToString($node);

XML::Bare is a minimal XML parser implemented via a C state engine.

SYNOPSIS

use XML::Bare;

my $xml = new XML::Bare( text => Bob );

# Parse the xml into a hash tree
my $root = $xml->parse();

# Print the content of the name node
print $root->{xml}->{name}->{value};

# Load xml from a file ( assume same contents as first example )
my $xml2 = new XML::Bare( file => test.xml );

my $root2 = $xml2->parse();

$root2->{xml}->{name}->{value} = Tim;

# Save the changes back to the file
$xml2->save();
