A library for performing interesting tasks with DOM objects.
Class | NodeLookupError | Undocumented |
Function | substitute | Look through the given node's children for strings, and attempt to do string substitution with the given parameter. |
Function | get | Get a node with the specified nodeId as any of the
class , id or pattern attributes. If
there is no such node, raise NodeLookupError . |

class , id or pattern attributes. If
there is no such node, return None . |
Function | getAndClear | Get a node with the specified nodeId as any of the
class , id or pattern attributes. If
there is no such node, raise NodeLookupError .
Remove all child nodes before returning. |
Function | clearNode | Remove all children from the given node. |

Function | _get | (internal) Get a node with the specified nodeId as any of
the class , id or pattern
attributes. |
Look through the given node's children for strings, and attempt to do string substitution with the given parameter.
(internal) Get a node with the specified nodeId
as any of
the class
, id
or pattern
attributes.
Get a node with the specified nodeId
as any of the
class
, id
or pattern
attributes. If
there is no such node, raise NodeLookupError
.
Get a node with the specified nodeId
as any of the
class
, id
or pattern
attributes. If
there is no such node, return None
.
Get a node with the specified nodeId
as any of the
class
, id
or pattern
attributes. If
there is no such node, raise NodeLookupError
.
Remove all child nodes before returning.
Find subnodes in the given node where the given attribute has the given value.
Visit each child node and collect its text data, if any, into a string. For example:
>>> doc=microdom.parseString('<a>1<b>2<c>3</c>4</b></a>') >>> gatherTextNodes(doc.documentElement) '1234'
With dounescape=1, also convert entities back into normal characters.
Returns | the gathered nodes as a single string (type: str) |
Return an iterable of the elements which are direct children of
parent
and which have the attribute
attribute.
Return an iterable of the elements which are children of
parent
for which the predicate matcher
returns
true.
