            XSLT

XSLT(self, xslt_input, extensions=None, regexp=True, access_control=None)

Turn an XSL document into an XSLT object.

Calling this object on a tree or Element will execute the XSLT:

    >>> transform = etree.XSLT(xsl_tree)
    >>> result = transform(xml_tree)

Keyword arguments of the constructor:

- extensions: a dict mapping `(namespace, name)` pairs to extension functions or extension elements
- regexp: enable exslt regular expression support in XPath (default: True)
- access_control: access restrictions for network or file system (see XSLTAccessControl)

Keyword arguments of the XSLT call:

- profile_run: enable XSLT profiling (default: False)

Other keyword arguments of the call are passed to the stylesheet as parameters.

### __call__(self, _input, profile_run=False, **kw)
(Call operator)

Execute the XSL transformation on a tree or Element.

Pass the `profile_run` option to get profile information about the XSLT. The result of the XSLT will have a property xslt_profile that holds an XML tree with profiling data.

### __init__(self, xslt_input, extensions=None, regexp=True, access_control=None)
(Constructor)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__

### __new__(T, S, ...)

Returns: a new object with type S, a subtype of T
Overrides: object.__new__

### apply(self, _input, profile_run=False, **kw)

Deprecated: call the object, not this method.

### strparam(strval)

Mark an XSLT string parameter that requires quote escaping before passing it into the transformation. Use it like this:

    result = transform(doc, some_strval = XSLT.strparam(
        '''it's "Monty Python's" ...'''))

Escaped string parameters can be reused without restriction.

### tostring(self, result_tree)

Save result doc to string based on stylesheet output method.

Deprecated: use str(result_tree) instead.
