solrpy pagnator batch

i use solr1.4.1 version,and the return xml is changed, the original return xml is like this 012test ... ... document_idsome test text ... 2 ... some test text ... ... in responseHeader node has params sub node,but the new version(1.4.1),cancle it,so we need hack some code to fix this isuue. so when use the default paginator has one issue, when i invoke it will thrown errors as follows: class SolrPaginator: """ Create a Django-like Paginator for a solr response object.
