Dominate
Dominate is a Python library for creating and manipulating HTML documents using an elegant DOM API.
It allows you to write HTML pages in pure Python very concisely, which eliminates the need to learn another template language, and lets you take advantage of the more powerful features of Python.
Python:
import dominate
from dominate.tags import *
doc = dominate.document(title='Dominate your HTML')
with doc.head:
link(rel='stylesheet', href='style.css')
script(type='text/javascript', src='script.js')
with doc:
with div(id='header').add(ol()):
for i in ['home', 'about', 'contact']:
li(a(i.title(), href='/%s.html' % i))
with div():
attr(cls='body')
p('Lorem ipsum..')
print(doc)
Output:
<!DOCTYPE html>
<html>
<head>
<title>Dominate your HTML</title>
<link href="https://github.com/Knio/dominate/raw/2.9.1/style.css" rel="stylesheet">
<script src="https://github.com/Knio/dominate/raw/2.9.1/script.js" type="text/javascript"></script>
</head>
<body>

Examples
All examples assume you have imported the appropriate tags or entire tag set:
from dominate.tags import *
Hello, World!
The most basic feature of dominate exposes a class for each HTML element, where the constructor
accepts child elements, text, or keyword attributes. dominate nodes return their HTML representation
from the __str__, __unicode__, and render() methods.
print(html(body(h1('Hello, World!'))))
<html>
<body>
<h1>Hello, World!</h1>
</body>
</html>
Attributes
Dominate can also use keyword arguments to append attributes onto your tags. Most of the attributes are a direct copy from the HTML spec with a few variations.
For attributes class and for which conflict with Python's reserved keywords, you can use the following aliases:
| class | for |
|---|---|
| _class | _for |
| cls | fr |
| className | htmlFor |
| class_name | html_for |
test = label(cls='classname anothername', fr='someinput')
print(test)
<label class="classname anothername" for="someinput"></label>
Use data_* for custom HTML5 data attributes.
test = div(data_employee='101011')
print(test)
You can also modify the attributes of tags through a dictionary-like interface:
header = div()
header['id'] = 'header'
print(header)
Complex Structures
Through the use of the += operator and the .add() method you can easily create more advanced structures.
Create a simple list:
list = ul()
for item in range(4):
list += li('Item #', item)
print(list)
<ul>
<li>Item #0</li>
<li>Item #1</li>
<li>Item #2</li>
<li>Item #3</li>
</ul>
dominate supports iterables to help streamline your code:
print(ul(li(a(name, href=link), __pretty=False) for name, link in menu_items))
<ul>
<li><a href="https://github.com/Knio/dominate/raw/2.9.1/home/">Home</a></li>
<li><a href="https://github.com/Knio/dominate/raw/2.9.1/about/">About</a></li>
<li><a href="https://github.com/Knio/dominate/raw/2.9.1/downloads/">Downloads</a></li>
<li><a href="https://github.com/Knio/dominate/raw/2.9.1/links/">Links</a></li>
</ul>
A simple document tree:
_html = html()
_body = _html.add(body())
header = _body.add(div(id='header'))
content = _body.add(div(id='content'))
footer = _body.add(div(id='footer'))
print(_html)
<html>
<body>
</body>
</html>
For clean code, the .add() method returns children in tuples. The above example can be cleaned up and expanded like this:
_html = html()
_head, _body = _html.add(head(title('Simple Document Tree')), body())
names = ['header', 'content', 'footer']
header, content, footer = _body.add([div(id=name) for name in names])
print(_html)
<html>
<head>
<title>Simple Document Tree</title>
</head>
<body>
</body>
</html>
You can modify the attributes of tags through a dictionary-like interface:
header = div()
header['id'] = 'header'
print(header)
Or the children of a tag though an array-line interface:
header = div('Test')
header[0] = 'Hello World'
print(header)
Hello World
Comments can be created using objects too!
print(comment('BEGIN HEADER'))
print(comment(p('Upgrade to newer IE!'), condition='lt IE9'))
Rendering
By default, render() tries to make all output human readable, with one HTML
element per line and two spaces of indentation.
This behavior can be controlled by the __pretty (default: True except for
certain element types like pre) attribute when creating an element, and by
the pretty (default: True), indent (default: ) and xhtml (default: False)
arguments to render(). Rendering options propagate to all descendant nodes.
a = div(span('Hello World'))
print(a.render())
<span>Hello World</span>
print(a.render(pretty=False))
<span>Hello World</span>
print(a.render(indent='\t'))
<span>Hello World</span>
a = div(span('Hello World'), __pretty=False)
print(a.render())
<span>Hello World</span>
d = div()
with d:
hr()
p("Test")
br()
print(d.render())
print(d.render(xhtml=True))
<hr>
Test
<hr />
Test
Context Managers
You can also add child elements using Python's with statement:
h = ul()
with h:
li('One')
li('Two')
li('Three')
print(h)
<ul>
<li>One</li>
<li>Two</li>
<li>Three</li>
</ul>
You can use this along with the other mechanisms of adding children elements, including nesting with statements, and it works as expected:
h = html()
with h.add(body()).add(div(id='content')):
h1('Hello World!')
p('Lorem ipsum ...')
with table().add(tbody()):
l = tr()
l += td('One')
l.add(td('Two'))
with l:
td('Three')
print(h)
<html>
<body>
<h1>Hello World!</h1>
Lorem ipsum ...
<table>
<tbody>
<tr>
<td>One</td>
<td>Two</td>
<td>Three</td>
</tr>
</tbody>
</table>
</body>
</html>
When the context is closed, any nodes that were not already added to something get added to the current context.
Attributes can be added to the current context with the attr function:
d = div()
with d:
attr(id='header')
print(d)
```
```html
And text nodes can be added with the dominate.util.text function:
from dominate.util import text
para = p(__pretty=False)
with para:
text('Have a look at our ')
a('other products', href='/products')
print(para)
Have a look at our <a href="https://github.com/Knio/dominate/raw/2.9.1/products">other products</a>
Decorators
Dominate is great for creating reusable widgets for parts of your page. Consider this example:
def greeting(name):
with div() as d:
p('Hello, %s' % name)
return d
print(greeting('Bob'))
Hello, Bob
You can see the following pattern being repeated here:
def widget(parameters):
with tag() as t:
...
return t
This boilerplate can be avoided by using tags (objects and instances) as decorators
@div
def greeting(name):
p('Hello %s' % name)
print(greeting('Bob'))
Hello Bob
The decorated function will return a new instance of the tag used to decorate it, and execute in a with context which will collect all the nodes created inside it.
You can also use instances of tags as decorators, if you need to add attributes or other data to the root node of the widget. Each call to the decorated function will return a copy of the node used to decorate it.
@div(h2('Welcome'), cls='greeting')
def greeting(name):
p('Hello %s' % name)
print(greeting('Bob'))
<h2>Welcome</h2>
Hello Bob
Creating Documents
Since creating the common structure of an HTML document everytime would be excessively tedious dominate provides a class to create and manage them for you: document.
When you create a new document, the basic HTML tag structure is created for you.
d = document()
print(d)
<!DOCTYPE html>
<html>
<head>
<title>Dominate</title>
</head>
<body></body>
</html>
The document class accepts title, doctype, and request keyword arguments.
The default values for these arguments are Dominate, <!DOCTYPE html>, and None respectively.
The document class also provides helpers to allow you to access the title, head, and body nodes directly.
d = document()
>>> d.head
<dominate.tags.head: 0 attributes, 1 children>
>>> d.body
<dominate.tags.body: 0 attributes, 0 children>
>>> d.title
u'Dominate'
The document class also provides helpers to allow you to directly add nodes to the body tag.
d = document()
d += h1('Hello, World!')
d += p('This is a paragraph.')
print(d)
<!DOCTYPE html>
<html>
<head>
<title>Dominate</title>
</head>
<body>
<h1>Hello, World!</h1>
This is a paragraph.
</body>
</html>
Embedding HTML
If you need to embed a node of pre-formed HTML coming from a library such as markdown or the like, you can avoid escaped HTML by using the raw method from the dominate.util package:
from dominate.util import raw
...
td(raw('<a href="https://github.com/Knio/dominate/raw/2.9.1/example.html">Example</a>'))
Without the raw call, this code would render escaped HTML with lt, etc.
SVG
The dominate.svg module contains SVG tags similar to how dominate.tags contains HTML tags. SVG elements will automatically convert _ to - for dashed elements. For example:
from dominate.svg import *
print(circle(stroke_width=5))
<circle stroke-width="5"></circle>
