Hi,
I am beginners with scrapy and also with the python. So far I could manage
to create some basic spiders based on given examples in scrapy doc.
Now I would like to extend the default features according to custom
requirement. Atm I am trying to change the default tag names in output xml.
For example,
1) By default it generates xml with item_element='item' and
root_element='items', instead I want to change it to item_element='ad' and
root_element='ads'. Also how to remove multi-value fields are exported by each
value
inside the <value> element
Send me sample source code for above queries...
Thanks,
Sachin
