XML (and XHTML) Generation
|
|
==========================
|
|
|
|
The elements generator lets you easily create snippets of XML or XHTML:
|
|
|
|
>>> from cybertools.xml.element import elements as e
|
|
>>> doc = e.html(
|
|
... e.head(e.title(u'Page Title')),
|
|
... e.body(
|
|
... e.div(u'The top bar', class_=u'top'),
|
|
... e.div(u'The body stuff', class_=u'body'),
|
|
... ))
|
|
|
|
>>> print doc.render()
|
|
<html>
|
|
<head>
|
|
<title>
|
|
Page Title
|
|
</title>
|
|
</head>
|
|
<body>
|
|
<div class="top">
|
|
The top bar
|
|
</div>
|
|
<div class="body">
|
|
The body stuff
|
|
</div>
|
|
</body>
|
|
</html>
|
|
|
|
An XML element thus created may be converted to an ElementTree (the standard
|
|
implementation in fact uses an lxml.etree structure as its basis):
|
|
|
|
>>> doc.renderTree()
|
|
'<html><head><title>Page Title</title></head><body><div class="top">The top bar</div><div class="body">The body stuff</div></body></html>'
|
|
|
|
>>> tree = doc.makeTree()
|
|
>>> tree.findtext('head/title')
|
|
'Page Title'
|
|
|
|
>>> xml = ('<html><head><title>Page Title</title></head><body>'
|
|
... '<div class="top">The top bar</div>'
|
|
... '<div class="body">The body stuff</div></body></html>')
|
|
>>> from cybertools.xml.element import fromXML
|
|
>>> doc = fromXML(xml)
|
|
>>> print doc.render()
|
|
<html>
|
|
<head>
|
|
<title>
|
|
Page Title
|
|
</title>
|
|
</head>
|
|
<body>
|
|
<div class="top">
|
|
The top bar
|
|
</div>
|
|
<div class="body">
|
|
The body stuff
|
|
</div>
|
|
</body>
|
|
</html>
|
|
|
|
Alternative Notation
|
|
--------------------
|
|
|
|
We can also create such a structure by successively adding elements
|
|
just by accessing an element's attributes:
|
|
|
|
>>> doc = e.html
|
|
>>> dummy = doc.head.title(u'Page Title')
|
|
>>> body = doc.body
|
|
>>> div1 = body.div(u'The top bar', class_=u'top')
|
|
>>> div2 = body.div(u'The body stuff', class_=u'body')
|
|
>>> print doc.render()
|
|
<html>
|
|
<head>
|
|
<title>
|
|
Page Title
|
|
</title>
|
|
</head>
|
|
<body>
|
|
<div class="top">
|
|
The top bar
|
|
</div>
|
|
<div class="body">
|
|
The body stuff
|
|
</div>
|
|
</body>
|
|
</html>
|
|
|
|
>>> for text in (u'Welcome', u'home'):
|
|
... p = div2.p(text, style='font-size: 80%;')
|
|
>>> print doc.render()
|
|
<html>...<p...>...</p>...
|
|
|
|
>>> x = p('Some more text').b('bold text')
|
|
>>> x = p('and normal again')
|
|
>>> print p.render()
|
|
<p...>...home...Some more text
|
|
<b>...bold text...</b>
|
|
...and normal again
|
|
</p>
