# Online W3C Validator

Pure Python command line for HTML validation using W3C online validator. It could be very handy for using it in a CI pipline.

## Installation

```bash
pip install -U Online-W3C-Validator
```

## How to use

You can user the CLI command:

```bash
w3c_validator http://www.google.com some_file.html
```

Example output:

```
INFO:w3c_validator.validator:Files to validate:
http://www.google.com
INFO:w3c_validator.validator:Number of files: 1
INFO:w3c_validator.validator:validating: http://www.google.com ...
error: line 2: CSS: “display”: “inline-box” is not a “display” value in “inline-box” in “.ds”.
error: line 2: The “bgcolor” attribute on the “body” element is obsolete. Use CSS instead.
error: line 5: Element “nobr” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
error: line 5: Attribute “width” not allowed on element “div” at this point.
error: line 5: Element “nobr” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
error: line 5: The “center” element is obsolete. Use CSS instead.

```

Or you can use the fuction **validdate** provied by the package, that thakes either HTML file name or URL as a single parameter an returns JSON object with the validation output.

```py
from w3c_validator import validate

messages = validate("http://www.google.com")["messages"]
for m in messages:
print("Type: %(type)s, Line: %(lastLine)d, Description: %(message)s" % m)
```
