A simple-to-use XML module, for parsing and creating XML documents


This module can parse XML comments, CDATA sections, XML entities (the standard five and numeric ones) and simple non-recursive <!ENTITY>s

It will ignore (won't parse) <!DOCTYPE...>, <?...?> and other <!...> special markup

Parsed documents must be UTF-8 encoded, as will all XML documents produced by this module be

XML documents to be parsed may not contain the > character unencoded in attribute values


Some functions and methods in this module accept optional flags, listed under each function in the documentation. They are optional, default to zero unless stated otherwise, and can be used as follows: &function_name( $param1, { flag1 => 1, flag2 => 1 } ). This is what each flag does:

strip : the function will strip initial and ending whitespace from all text values returned

file : the function will expect the path to a file containing an XML document to parse, instead of an XML string

complete : the function's XML output will include an XML declaration (<?xml ... ?>) in the beginning

soft : the function will return undef instead of dying in case of an error during XML parsing

internal : the function will only return the contents of an element in a hashref instead of the element itself (see "SYNOPSIS" for example)

tidy : the function will return tidy XML

indentstring : when producing tidy XML, this denotes the string with which child elements will be indented (Default is the 'tab' character)

save : the function (apart from doing what it's supposed to do) will also save its XML output in a file whose path is denoted by this flag

strip_ns : strip the namespaces (characters up to and including ':') from the tags

xslt : will add a <?xml-stylesheet?> link in the XML that's being output, of type 'text/xsl', pointing to the filename or URL denoted by this flag

arrayref : the function will create a simple arrayref instead of a simple hashref (which will preserve order and elements with duplicate tags)

utf8 : the strings which will be returned will have their utf8 flag set (defaults to 0 for compatibility with software built with older versions of this module). The way this module works is that it holds everything in byte format internally (even if you provide it with a utf8 XML string), and then produces utf8 strings or simple structures if (and only if) asked for with this flag. UTF is an important issue, please read perldoc utf8 for more.



Returns the XML string in a tidy format (with tabs & newlines)

Optional flags: file, complete, indentstring, soft, save, utf8


Creates an 'XML::MyXML::Object' object from the raw XML provided

Optional flags: file, soft


Creates an XML string from the 'XML::MyXML::Object' object provided

Optional flags: complete, tidy, indentstring, save, utf8


Produces a raw XML string from either an array reference, a hash reference or a mixed structure such as these examples:

    { thing => { name => 'John', location => { city => 'New York', country => 'U.S.A.' } } }
    [ thing => [ name => 'John', location => [ city => 'New York', country => 'U.S.A.' ] ] ]
    { thing => { name => 'John', location => [ city => 'New York', city => 'Boston', country => 'U.S.A.' ] } }

Optional flags: complete, tidy, indentstring, save, xslt, utf8


Produces a very simple hash object from the raw XML string provided. An example hash object created thusly is this: { thing => { name => 'John', location => { city => 'New York', country => 'U.S.A.' } } }

Since the object created is a hashref, duplicate keys will be discarded. WARNING: This function only works on very simple XML strings, i.e. children of an element may not consist of both text and elements (child elements will be discarded in that case)

Optional flags: internal, strip, file, soft, strip_ns, arrayref, utf8


Returns 1 if the $raw_xml string is valid XML (valid enough to be used by this module), and 0 otherwise.

Optional flags: file



Returns the element specified by the path as an XML::MyXML::Object object. When there are more than one tags with the specified name in the last step of the path, it will return all of them as an array. In scalar context will only return the first one.


When the element represented by the $obj object has only text contents, returns those contents as a string. If the $obj element has no contents, value will return an empty string.

Optional flags: strip, utf8


Returns the value of the 'attrname' attribute of top element. Returns undef if attribute does not exist.

Optional flags: utf8


Returns the tag of the $obj element (after stripping it from namespaces). E.g. if $obj represents an <rss:item> element, $obj->tag will just return the name 'item'. Returns undef if $obj doesn't represent a tag.

Optional flags: utf8


Returns a very simple hashref, like the one returned with &XML::MyXML::xml_to_simple. Same restrictions and warnings apply.

Optional flags: internal, strip, strip_ns, arrayref, utf8


Returns the XML string of the object, just like calling &object_to_xml( $obj )

Optional flags: complete, tidy, indentstring, save, utf8


Returns the XML string of the object in tidy form, just like calling &tidy_xml( &object_to_xml( $obj ) )

Optional flags: complete, indentstring, save, utf8
