NAME
XML::Parser::Wrapper - A simple object wrapper around XML::Parser
SYNOPSIS
use XML::Parser::Wrapper;
my $xml = qq{Hello World!};
my $root = XML::Parser::Wrapper->new($xml);
my $root2 = XML::Parser::Wrapper->new({ file => '/tmp/test.xml' });
my $root_tag_name = $root->name;
my $roots_children = $root->elements;
foreach my $element (@$roots_children) {
if ($element->name eq 'head') {
my $id = $element->attr('id');
my $hello_world_text = $element->text; # eq "Hello World!"
}
}
my $head_element = $root->element('head2');
my $head_elements = $root->elements('head2');
my $test = $root->element('head2')->element('test_tag');
DESCRIPTION
XML::Parser::Wrapper provides a simple object around XML::Parser
to make it more convenient to deal with the parse tree returned
by XML::Parser.
METHODS
new($xml), new({ file => $filename })
Calls XML::Parser to parse the given XML and returns a new
XML::Parser::Wrapper object using the parse tree output from
XML::Parser.
name()
Returns the name of the element represented by this object.
Aliases: tag(), getName(), getTag()
is_text()
Returns a true value if this element is a text element, false
otherwise.
Aliases: isText()
text()
If this element is a text element, the text is returned.
Otherwise, return the text from the first child text element, or
undef if there is not one.
Aliases: content(), getText(), getContent()
html()
Like text(), except HTML-escape the text (escape &, <, >, and ")
before returning it.
Aliases: content_html(), getContentHtml()
xml()
Like text(), except XML-escape the text (escape &, <, >, and ")
before returning it.
Aliases: content_xml(), getContentXml()
attributes(), attributes($name1, $name2, ...)
If no arguments are given, returns a hash of attributes for this
element. If arguments are present, an array of corresponding
attribute values is returned. Returns an array in array context
and an array reference if called in scalar context.
E.g.,
bar
my ($name, $id) = $element->attributes('name', 'id');
Aliases: attrs(), getAttributes(), getAttrs()
attribute($name)
Similar to attributes(), but only returns one value.
Aliases: attr(), getAttribute(), getAttr()
elements(), elements($element_name)
Returns an array of child elements. If $element_name is passed,
a list of child elements with that name is returned.
Aliases: getElements(), kids(), getKids(), children(), getChildren()
first_element(), first_element($element_name)
Returns the first child element of this element. If
$element_name is passed, returns the first child element with
that name is returned.
Aliases: getFirstElement(), kid(), first_kid()
first_element_if($element_name)
Like first_element(), except if there is no corresponding child,
return an object that will work instead of undef. This allows
for reliable chaining, e.g.
my $class = $root->kid_if('field')->kid_if('field')->kid_if('element')
->kid_if('field')->attribute('class');
Aliases: getFirstElementIf(), kidIf(), first_kid_if()
simple_data()
Assume a data structure of hashes, arrays, and strings are
represented in the xml with no attributes. Return the data
structure, leaving out the root tag.
dump_simple_data($data)
The reverse of simple_data() -- return xml representing the data
structure passed.
