| 65 :: | 65 The ``Stream`` class provides a ``select(path)`` function that can be used to |
| 66 retrieve subsets of the stream: | |
| 66 | 67 |
| 67 from genshi.input import XML | 68 .. code-block:: pycon |
| 68 | 69 |
| 69 doc = XML('''<doc> | 70 >>> from genshi.input import XML |
| 70 <items count="2"> | 71 |
| 71 <item status="new"> | 72 >>> doc = XML('''<doc> |
| 72 <summary>Foo</summary> | 73 ... <items count="2"> |
| 73 </item> | 74 ... <item status="new"> |
| 74 <item status="closed"> | 75 ... <summary>Foo</summary> |
| 75 <summary>Bar</summary> | 76 ... </item> |
| 76 </item> | 77 ... <item status="closed"> |
| 77 </items> | 78 ... <summary>Bar</summary> |
| 78 </doc>''') | 79 ... </item> |
| 79 print doc.select('items/item[@status="closed"]/summary/text()') | 80 ... </items> |
| 80 | 81 ... </doc>''') |
| 81 This would result in the following output:: | 82 |
| 82 | 83 >>> print doc.select('items/item[@status="closed"]/summary/text()') |
