Not all browsers support negative array indices so I provide a last() method on the array to easily get at the last element.
I tested your HTML snippet with the my latest version (from both GitHub and NPM) and it works:
var sys = require("sys");
var htmlparser = require("htmlparser");
var html = "<html><body><p>foo</p></body></html>";
var handler = new htmlparser.DefaultHandler(function(err, dom) {
if (err)
sys.debug("Error: " + err);
else
sys.debug(sys.inspect(dom, false, null));
}, { enforceEmptyTags: true });
var parser = new htmlparser.Parser(handler);
parser.parseComplete(html);
...produces the output:
DEBUG: [ { raw: 'html',
data: 'html',
type: 'tag',
name: 'html',
children:
[ { raw: 'body',
data: 'body',
type: 'tag',
name: 'body',
children:
[ { raw: 'p',
data: 'p',
type: 'tag',
name: 'p',
children: [ { raw: 'foo', data: 'foo', type: 'text' } ] } ] } ] } ]
No errors occur. What version of the parser lib are you working with?
from node-htmlparser.
'-1' is a prop just like anything else. Also function assign names are implied, so you dont need this grossness :p "DefaultHandler$_tagStack$last"
from node-htmlparser.
Sorry, I have been working with perl again lately, which allows a negative array index. Not sure sure why tagStack.last()
fails but tagStack['-1']()
does not; what happens for tagStack['last']()
?
The reason for the "grossness" is to have more useful stack traces when an exception is thrown. Without the explicit naming, the functions names are blank and without the "Class$Method" format, classes that have the same method names will leave ambiguous call stacks.
See this gist for example code:
https://gist.github.com/748644
The output of the example is the following:
No method names
()@file:///.../example.html:7
@file:///.../example.html:31
Short method names:
ShortName()@file:///.../example.html:10
@file:///.../example.html:37
Full method names:
Example$FullName()@file:///.../example.html:13
@file:///.../example.html:43
Short method names with multiple classes with the same method names (ambiguous):
ShortName()@file:///.../example.html:10
ShortName()@file:///.../example.html:21
@file:///.../example.html:49
Full method names with multiple classes with the same method names (concise):
Example$FullName()@file:///.../example.html:13
ExampleDupeMethods$FullName()@file:///.../example.html:24
@file:///.../example.html:55
from node-htmlparser.
