##### Modifying/replacing a node

##### Searching child nodes |
|
| 209 |
|
|
| 210 | 219 |
def by_tag_name(node, name, last_only=False, ignore_namespace=False): |
| 211 | 220 |
'''last_only optimization returns only the last matching node''' |
| 212 | 221 |
if ignore_namespace: filter_name = strip_namespace |
Also available in: Unified diff
xml_dom.py: Added value_node(). Use new value_node() in value() and set_value(). set_value(): If the node already has a value node, reuse it instead of appending a new value node.
