Abstract: Full text retrieval based on XML is the foundation of many related research problems,such as WEB information retrieval and information extraction.Furthermore,an efficiently XML index structure is very important to accelerate retrieval.An index structure based on the node labeling schema[1] is constructed and implemented in this paper,the index structure could effectively support full text retrieval queries.At last,the comprehensive experiments are conducted,the experiment results show the index structure is better on consumed time and storage.

Key words: XML, full text retrieval, index
