NAME
PFT::Text::Symbol - Symbol from text scan
SYNOPSIS
my $array = PFT::Text::Symbol->scan_html($your_html_text);
foreach (PFT::Text::Symbol->scan_html($your_html_text)) {
die unless $_->isa('PFT::Text::Symbol')
};
DESCRIPTION
Each instance of PFT::Text::Symbol
represents a symbol obtained by parsing the text of an entry PFT::Content::Entry
: they are detected as <a>
and <img>
tags in HTML. Symbols are collected into a a PFT::Text
object.
An example will make this easy to understand. Let's consider the following tag:
<img src=":key1:a1/b1/c1">
It will generate a symbol $s1
such that:
$s1->keyword
iskey1
;$s1->args
is the list(a1, b1, c1)
;$s1->start
points to the first:
character;$s1->len
points to the last1
character;
Since a block of HTML can possibly yield multiple symbols, there's no public construction. Use the scan_html
multi-constructor instead.
Construction
Construction usually goes through PFT::Text::Symbol->scan_html
, which expects an HTML string as parameter and returns a list of blessed symbols.
For other needs (e.g. testing):
PFT::Text::Symbol->new($keyword, [$arg1, …, $argn], $start, $length)
