HTML parser
It return a table with the html tree
<html><body>
<p>
Click <a href="http://example.com/">here!</a>
<p>
Hello
</p>
</body></html>
Then, the parser produces the following table:
{
_tag = "#document",
_attr = {},
{
_tag = "html",
_attr = {},
{
_tag = "body",
_attr = {},
"\n",
{
_tag = "p",
_attr = {},
"\n Click ",
{
_tag = "a",
_attr = {href = "http://example.com/"}
"here!",
},
"\n",
},
{
_tag = "p",
_attr = {},
"\n Hello\n",
},
"\n",
}
}
}Usage:
os.loadAPI("html")
a = html.getTable(filename)
–code to use that table
or you can use the function with io.stdin using html.parse(io.stdin) instead of html.getTable or you can parse a single string using html.parsestr(str)

pastebin: pastebin get hzYsY0wW html
Currently im working in the next version of this that give you the capability to redner all the thing into a GUI but i cant find a way to read the table and obtain all the elements and a gui api that is enought complete to do itXML parser
example: pastebin get hDEsi2ZE test –(it creates a xml string and parse it)
README
<test one="two"> <three four="five" four="six"/> <three>eight</three> <nine ten="eleven">twelve</nine></test>
You can access values in two ways:
Using the simple method:
xml.test["@one"] == "two"xml.test.nine["@ten"] == "eleven"xml.test.nine:value() == "twelve"xml.test.three[1]["@four"][1] == "five"xml.test.three[1]["@four"][2] == "six"xml.test.three[2]:value() == "eight"
or if your XML is a little bit more complicated you can do it like this:
xml:children()[1]:name() == "test"xml:children()[1]:children()[2]:value() == "eight"xml:properties()[1] == {name = "one", value = "two"}
Limitations
There's no support for namespaces. When I see namespaces I immediately start to remember days when I worked at corporate. We had to use namespaces only because XML was so convoluted we would not be able to handle it without them. In the end XML parsing took longer for some APIs then actual logic of the API. If you're in this situation it is better to step back and do something about it rather than asking for namespace support. I am using this module to read fairly simple XML. Even if it is a large XML string, the structure is still simple, so I was not able to test it properly. Please create a new Issue if you spot a problem. Please take a loook at xmlTest.lua for an example of use.
Final notes
This is a modified version from the modified version of Corona-XML-Module by Jonathan Beebe which in turn is based on Alexander Makeev's Lua-only XML parser found here for working on cc luaPost suggestions/bugs!

I have recoded a html parser that i founded to be compatible with cc-luaIt return a table with the html tree
Spoiler
For example, if the following input is given:<html><body>
<p>
Click <a href="http://example.com/">here!</a>
<p>
Hello
</p>
</body></html>
Then, the parser produces the following table:
{
_tag = "#document",
_attr = {},
{
_tag = "html",
_attr = {},
{
_tag = "body",
_attr = {},
"\n",
{
_tag = "p",
_attr = {},
"\n Click ",
{
_tag = "a",
_attr = {href = "http://example.com/"}
"here!",
},
"\n",
},
{
_tag = "p",
_attr = {},
"\n Hello\n",
},
"\n",
}
}
}
os.loadAPI("html")
a = html.getTable(filename)
–code to use that table
or you can use the function with io.stdin using html.parse(io.stdin) instead of html.getTable or you can parse a single string using html.parsestr(str)

- Create a local variable local xml = require("xmlSimple.lua").newParser()
- Read xml using xml:ParseXmlText(xmlString) or xml:loadFile(xmlFilename, base)
