class LibXML::SAX::Builder
Builds SAX callback sets
Description
This class provides mappings from native SAX2 callbacks to Raku.
It may be used in conjunction with LibXML::SAX::Handler::SAX2 base-class.
Example
The following example builds a modified DOM tree with all tags and attributes converted to uppercase.
use LibXML::Document;
use LibXML::SAX::Builder;
use LibXML::SAX::Handler::SAX2;
class SAXShouter is LibXML::SAX::Handler::SAX2 {
use LibXML::SAX::Builder :sax-cb;
method startElement($name, |c) is sax-cb {
nextwith($name.uc, |c);
}
method endElement($name, |c) is sax-cb {
nextwith($name.uc, |c);
}
method characters($chars, |c) is sax-cb {
nextwith($chars.uc, |c);
}
}
my SAXShouter $sax-handler .= new();
my $string = '<html><body><h1>Hello World</h1></body></html>'
my LibXML::Document $doc .= parse: :$string, :$sax-handler;
say $doc.Str; # <HTML><BODY><H1>HELLO WORLD</H1></BODY></HTML>'See LibXML::SAX::Handler::SAX2 for a description of callbacks
