XML::Parser::Lite::Tree - Lightweight XML tree builder
use XML::Parser::Lite::Tree;
my $tree_parser = XML::Parser::Lite::Tree::instance();
my $tree = $tree_parser->parse($xml_data);
OR
my $tree = XML::Parser::Lite::Tree::instance()->parse($xml_data);
This is a singleton class for parsing XML into a tree structure. How does this
differ from other XML tree generators? By using XML::Parser::Lite, which is a
pure perl XML parser. Using this module you can tree-ify simple XML without
having to compile any C.
For example, the following XML:
<foo woo="yay"><bar a="b" c="d" />hoopla</foo>
Parses into the following tree:
{
'children' => [
{
'children' => [
{
'children' => [],
'attributes' => {
'a' => 'b',
'c' => 'd'
},
'type' => 'element',
'name' => 'bar'
},
{
'content' => 'hoopla',
'type' => 'text'
}
],
'attributes' => {
'woo' => 'yay'
},
'type' => 'element',
'name' => 'foo'
}
],
'type' => 'root'
};
Each node contains a type key, one of root, element and text. root is the
document root, and only contains an array ref children. element represents a normal
tag, and contains an array ref children, a hash ref attributes and a string name.
text nodes contain only a content string.
- instance()
