stricter-htmlparser2


A forgiving HTML/XML/RSS parser. The parser can handle streams and provides a callback interface.

Installation

npm install 'stricter-htmlparser2'

A live demo of htmlparser2 is available here.

Differences to htmlparser2

1. Attribute value without quote wrapped is not allowed.

``


// output
{
attribs: {
name: "",
value: ""
}
}
`

2. "\"" is allowed in attribute value.

`


// output
{
attribs: {
name: "hello \\"world"
}
}
`

3. Record attributes key in a object that value is wrapped by single quote. The object is passed to onopentag method of parser's domhandler through the third argument.

`


// The third argument passed to onopentag:
{
name: true,
class: true
}
`

// If used with x-domhandler which is exported by this module, the parse result is like this:
`javascript
{
type: "tag",
name: "foo",
attribs: {
name: "{{flag ? \"true\" : \"false\"}}",
title: "title",
class: "hidden"
},
singleQuoteAttribs: {
name: true,
class: true
},
selfClose: false
}
`

4. Add selfClose flag to parsed node element.

Input:

`html

`

Parser code:
`javascript
const {Parser, DomHandler} = require('stricter-htmlparser2');

const parser = new Parser(new DomHandler(), {}).end(inputStr);
`

Output
`javascript
{
type: "tag",
name: "foo",
attribs: {
name: "{{flag ? \"true\" : \"false\"}}",
title: "title",
class: "hidden"
},
singleQuoteAttribs: {
name: true,
class: true
},
selfClose: true
}
`

Usage

`javascript
var htmlparser = require("stricter-htmlparser2");
var parser = new htmlparser.Parser({
onopentag: function(name, attribs){
if(name === "script" && attribs.type === "text/javascript"){
console.log("JS! Hooray!");
}
},
ontext: function(text){
console.log("-->", text);
},
onclosetag: function(tagname){
if(tagname === "script"){
console.log("That's it?!");
}
}
}, {decodeEntities: true});
parser.write("Xyz
