.SH NAME
XML::Smart \- A smart, easy and powerful way to access or create XML from fiels, data and URLs.
.SH VERSION
.IX Header "VERSION"
Version 1.79
.SH SYNOPSIS
.IX Header "SYNOPSIS"
This module provides an easy way to access/create XML data. It's based on a HASH
tree created from the XML data, and enables dynamic access to it through the 
standard Perl syntax for Hash and Array, without necessarily caring about which 
you are working with. In other words, \fBeach point in the tree works as a Hash and
an Array at the same time\fR!
.PP
This module additionally provides special resources such as: search for nodes by 
attribute, select an attribute value in each multiple node,  change the returned 
format, and so on.
.PP
The module also automatically handles binary data (encoding/decoding to/from base64),
CDATA (like contents with <tags>) and Unicode. It can be used to create XML files,
load XML from the Web ( just by using an URL as the file path ) and has an easy
way to send XML data through sockets \- just adding the length of the data in
the <?xml?> header.
.PP
You can use \fIXML::Smart\fR with XML::Parser, or with the 2 standard parsers of
XML::Smart:

.SH METHODS
.IX Header "METHODS"
.SS "new (FILE|DATA|URL , PARSER , OPTIONS)"
.IX Subsection "new (FILE|DATA|URL , PARSER , OPTIONS)"
Create a XML object.
.PP
\&\fBArguments:\fR
.IP FILE|DATA|URL 10
.IX Item "FILE|DATA|URL"
The first argument can be:
.Sp
.Vb 4
\&  \- XML data as string.
\&  \- File path.
\&  \- File Handle (GLOB).
\&  \- URL (Need LWP::UserAgent).
.Ve
.Sp
If not passed, a null XML tree is started, where you should create your own
XML data, than build/save/send it.
.IP "PARSER \fB(optional)\fR" 10
.IX Item "PARSER (optional)"
Set the XML parser to use. Options:
.Sp
.Vb 3
\&  XML::Parser
\&  XML::Smart::Parser
\&  XML::Smart::HTMLParser
.Ve
.Sp
\&\fIXML::Smart::Parser\fR can only handle basic XML data (not supported PCDATA, and any header like: ENTITY, NOTATION, etc...),
but is a good choice when you don't want to install big modules to parse XML, since it
comes with the main module. But it still can handle CDATA and binary data.
.Sp
** See \fI"PARSING HTML as XML"\fR for \fBXML::Smart::HTMLParser\fR.
.Sp
Aliases for the options:
.Sp
.Vb 2
\&  SMART|REGEXP   => XML::Smart::Parser
\&  HTML           => XML::Smart::HTMLParser
.Ve
.Sp
\&\fIDefault:\fR
.Sp
If not set it will look for XML::Parser and load it.
If XML::Parser can't be loaded it will use XML::Smart::Parser, which is actually a
clone of XML::Parser::Lite with some fixes.
.IP OPTIONS 10
.IX Item "OPTIONS"
You can force the uper case and lower case for tags (nodes) and arguments (attributes), and other extra things.
.RS 10
.IP lowtag 10
.IX Item "lowtag"
Make the tags lower case.
.IP lowarg 10
.IX Item "lowarg"
Make the arguments lower case.
.IP upertag 10
.IX Item "upertag"
Make the tags uper case.
.IP uperarg 10
.IX Item "uperarg"
Make the arguments uper case.
.IP arg_single 10
.IX Item "arg_single"
Set the value of arguments to 1 when they have a \fIundef\fR value.
.Sp
\&\fI** This option will work only when the XML is parsed by \fR\f(BIXML::Smart::HTMLParser\fR\fI, since it accept arguments without values:\fR
.Sp
.Vb 5
\&  my $xml = new XML::Smart(
\&  \*(Aq<root><foo arg1="" flag></root>\*(Aq ,
\&  \*(AqXML::Smart::HTMLParser\*(Aq ,
\&  arg_single => 1 ,
\&  ) ;
.Ve
.Sp
In this example the option "arg_single" was used, what will define \fIflag\fR to 1, but \fIarg1\fR will still have a null string value ("").
.Sp
Here's the tree of the example above:
.Sp
.Vb 6
\&  \*(Aqroot\*(Aq => {
\&              \*(Aqfoo\*(Aq => {
\&                         \*(Aqflag\*(Aq => 1,

.SS "apply_dtd (DTD , OPTIONS)"
.IX Subsection "apply_dtd (DTD , OPTIONS)"
Apply the \fIDTD\fR to the XML tree.
.PP
\&\fIDTD\fR can be a source, file, GLOB or URL.
.PP
This method is usefull if you need to have the XML generated by \fR\f(BIdata()\fR\fI\fR
formated in a specific DTD, so, elements will be nodes automatically,
attributes will be checked, required elements and attributes will be created,
the element order will be set, etc...
.PP
\&\fBOPTIONS:\fR
.IP "no_delete BOOL" 10
.IX Item "no_delete BOOL"
If TRUE tells that not defined elements and attributes in the DTD won't be deleted
from the XML tree.

Each query to the XML::Smart object return an object pointing to a different place
in the tree (and share the same HASH tree). So, you can get the main object
again (an object that points to the base):
.PP
.Vb 4
\&  my $srv = $XML\->{root}{host}{server} ;

\&  ## Access:
\&  
\&  my $content = $XML\->{foo}\->content ;

For this XML data:
.PP
.Vb 5

You can use the special parser \fBXML::Smart::HTMLParser\fR to "use" HTML as XML

.PP
The differences between an normal XML parser and \fIXML::Smart::HTMLParser\fR are:
.PP
.Vb 2
\&  \- Accept values without quotes:
\&    <foo bar=x>
\&    
\&  \- Accept any data in the values, including <> and &:
\&    <root><echo sample="echo \e"Hello!\e">out.txt"></root>
\&    
\&  \- Accpet URI values without quotes:
\&    <link url=http://www.foo.com/dir/file?query?q=v&x=y target=#_blank>
\&  
\&  \- Don\*(Aqt need to close the tags adding the \*(Aq/\*(Aq before \*(Aq>\*(Aq:
\&    <root><foo bar="1"></root>
\&    
\&    ** Note that the parse will try hard to detect the nodes, and where
\&       auto\-close or not.
\&  
\&  \- Don\*(Aqt need to have only one root:

.Ve
.PP
So, \fIXML::Smart::HTMLParser\fR is a willd way to load markuped data (like HTML),
or if you don't want to care with quotes, end tags, etc... when writing by hand your XML data.
So, you can write by hand a bad XML file, load it with \fIXML::Smart::HTMLParser\fR, and \fBrewrite well\fR
saving it again! ;\-P

\&  \-\-></SCRIPT>
.Ve
.SH ENTITIES

Entities (ENTITY) are handled by the parser. So, if you use XML::Parser it will do all the job fine.
But If you use \fIXML::Smart::Parser\fR or \fIXML::Smart::HMLParser\fR, only the basic entities (defaults)
will be parsed:
.PP
.Vb 5
\&  &lt;   => The less than sign (<).
\&  &gt;   => The greater than sign (>).
\&  &amp;  => The ampersand (&).
\&  &apos; => The single quote or apostrophe (\*(Aq).

\&  &#ddd;  => An ASCII character or an Unicode character (>255). Where ddd is a decimal.
\&  &#xHHH; => An Unicode character. Where HHH is in hexadecimal.
.Ve
.PP
\&\fBWhen creating XML data\fR, already existent Entities won't be changed, and the

.SH "WHY AND HOW IT WORKS"
.IX Header "WHY AND HOW IT WORKS"
Every one that have tried to use Perl HASH and ARRAY to access XML data, like in XML::Simple,
have some problems to add new nodes, or to access the node when the user doesn't know if it's
inside an ARRAY, a HASH or a HASH key. \fIXML::Smart\fR create around it a very dynamic way to
access the data, since at the same time any node/point in the tree can be a HASH and
an ARRAY. You also have other extra resources, like a search for nodes by attribute:
.PP
.Vb 1
\&  my $server = $XML\->{server}(\*(Aqtype\*(Aq,\*(Aqeq\*(Aq,\*(Aqsuse\*(Aq) ; ## This syntax is not wrong! ;\-)
\&
\&  ## Instead of:
\&  my $server = $XML\->{server}[1] ;
\&  
\&  _\|_DATA_\|_
\&  <hosts>
\&    <server os="linux" type="redhat" version="8.0">
\&    <server os="linux" type="suse" version="7.0">
\&  </hosts>
.Ve
.PP
The idea for this module, came from the problem that exists to access a complex struture in XML.
You just need to know how is this structure, something that is generally made looking the XML file (what is wrong).
But at the same time is hard to always check (by code) the struture, before access it.
XML is a good and easy format to declare your data, but to extrac it in a tree way, at least in my opinion,
isn't easy. To fix that, came to my mind a way to access the data with some query language, like SQL.
The first idea was to access using something like:
.PP
.Vb 1
\&  XML.foo.bar.baz{arg1}
\&
\&  X = XML.foo.bar*
\&  X.baz{arg1}
\&  
\&  XML.hosts.server[0]{argx}
.Ve
.PP
And saw that this is very similar to Hashes and Arrays in Perl:
.PP
.Vb 1
\&  $XML\->{foo}{bar}{baz}{arg1} ;
\&  
\&  $X = $XML\->{foo}{bar} ;
\&  $X\->{baz}{arg1} ;
\&  
\&  $XML\->{hosts}{server}[0]{argx} ;
.Ve
.PP
But the problem of Hash and Array, is not knowing when you have an Array reference or not.
For example, in XML::Simple:
.PP
.Vb 4
\&  ## This is very diffenrent
\&  $XML\->{server}{address} ;
\&  ## ... of this:
\&  $XML\->{server}{address}[0] ;
.Ve
.PP
So, why don't make both ways work? Because you need to make something crazy!
.PP
To create \fIXML::Smart\fR, first I have created the module Object::MultiType.
With it you can have an object that works at the same time as a HASH, ARRAY, SCALAR,
CODE & GLOB. So you can do things like this with the same object:
.PP
.Vb 1
\&  $obj = Object::MultiType\->new() ;
\&  
\&  $obj\->{key} ;
\&  $obj\->[0] ;
\&  $obj\->method ;  
\&  
\&  @l = @{$obj} ;
\&  %h = %{$obj} ;
\&  
\&  &$obj(args) ;
\&  
\&  print $obj "send data\en" ;
.Ve
.PP
Seems to be crazy, and can be more if you use \fBtie()\fR inside it, and this is what \fIXML::Smart\fR does.
.PP
For \fIXML::Smart\fR, the access in the Hash and Array way paste through \fBtie()\fR. In other words, you have a tied HASH
and tied ARRAY inside it. This tied Hash and Array work together, soo \fByou can access a Hash key
as the index 0 of an Array, or access an index 0 as the Hash key\fR:
.PP
.Vb 3
\&  %hash = (
\&  key => [\*(Aqa\*(Aq,\*(Aqb\*(Aq,\*(Aqc\*(Aq]
\&  ) ;
\&  
\&  $hash\->{key}    ## return $hash{key}[0]
\&  $hash\->{key}[0] ## return $hash{key}[0]  
\&  $hash\->{key}[1] ## return $hash{key}[1]
\&  
\&  ## Inverse:
\&  
\&  %hash = ( key => \*(Aqa\*(Aq ) ;
\&  
\&  $hash\->{key}    ## return $hash{key}
\&  $hash\->{key}[0] ## return $hash{key}
\&  $hash\->{key}[1] ## return undef
.Ve
.PP
The best thing of this new resource is to avoid wrong access to the data and warnings when you try to
access a Hash having an Array (and the inverse). Thing that generally make the script \fBdie()\fR.
.PP
Once having an easy access to the data, you can use the same resource to \fBcreate\fR data!
For example:
.PP
.Vb 4
\&  ## Previous data:
\&  <hosts>
\&    <server address="192.168.2.100" os="linux" type="conectiva" version="9.0"/>
\&  </hosts>
\&  
\&  ## Now you have {address} as a normal key with a string inside:
\&  $XML\->{hosts}{server}{address}
\&  
\&  ## And to add a new address, the key {address} need to be an ARRAY ref!
\&  ## So, XML::Smart make the convertion: ;\-P
\&  $XML\->{hosts}{server}{address}[1] = \*(Aq192.168.2.101\*(Aq ;
\&  
\&  ## Adding to a list that you don\*(Aqt know the size:
\&  push(@{$XML\->{hosts}{server}{address}} , \*(Aq192.168.2.102\*(Aq) ;
\&  
\&  ## The data now:
\&  <hosts>
\&    <server os="linux" type="conectiva" version="9.0"/>
\&      <address>192.168.2.100</address>
\&      <address>192.168.2.101</address>
\&      <address>192.168.2.102</address>
\&    </server>
\&  </hosts>
.Ve
.PP
Than after changing your XML tree using the Hash and Array resources you just
get the data remade (through the Hash tree inside the object):
.PP
.Vb 1
\&  my $xmldata = $XML\->data ;
.Ve
.PP
\&\fBBut note that \fR\f(BIXML::Smart\fR\fB always return an object\fR! Even when you get a final
key. So this actually returns another object, pointhing (inside it) to the key:
.PP
.Vb 1
\&  $addr = $XML\->{hosts}{server}{address}[0] ;
\&  
\&  ## Since $addr is an object you can TRY to access more data:
\&  $addr\->{foo}{bar} ; ## This doens\*(Aqt make warnings! just return UNDEF.
\&
\&  ## But you can use it like a normal SCALAR too:
\&
