[rules-users] Search a keyword in xml file content using jcr:contains() query in jackrabbit

Hi, In jackrabbit, How to search a keyword in a xml file using jcr:contains() Xpath query without interfering xml node? Eg: I have a content property in a blog entry node 'book'. content is represented as xml file (<*j2ee*>Introduction to x design pattern</*j2ee*>). If I search a word 'j2ee', its returning the node which is not currect conceptually. Please suggest me the possible approch either to use 'regular expression' or alternative way to resolve this requirement. //Keyword search StringBuffer queryStr = *new* StringBuffer(); queryStr.append("//book[jcr:contains(@bookContent,'"); queryStr.append("j2ee"); //queryStr.append("j??e"); queryStr.append("')]"); Query query = queryManager.createQuery(queryStr.toString(), Query.*XPATH*); QueryResult queryResult = query.execute(); Regards, Riyaz
