[ http://issues.apache.org/jira/browse/JCR-579?page=comments#action_12442625 ] Marcel Reutegger commented on JCR-579: --------------------------------------
Hi Christoph, I agree with you. Specifically with jackrabbit where the version storage is exposed with two hex digits for the intermediate nodes to the version history this encoding caused confusion several times already. The jackrabbit commons jar file contains an encoding utility that you can use: o.a.j.util.ISO9075. It takes away the pain, but it still itches, I know ... > "Digit" name support missing in XPath AQT parser. > ------------------------------------------------- > > Key: JCR-579 > URL: http://issues.apache.org/jira/browse/JCR-579 > Project: Jackrabbit > Issue Type: Bug > Components: query > Affects Versions: 1.0.1 > Reporter: Eugene Porubaev > Assigned To: Jukka Zitting > Priority: Critical > > INTRODUCTION: > According to JSR-170-ch.4.6"Path Syntax" a syntactically valid path is: > ... > name ::= [prefix ':'] simplename > simplename ::= onecharsimplename | twocharsimplename | threeormorecharname > onecharsimplename ::= /* Any Unicode character except: '.', '/', ':', '[', > ']', '*', ''', '"', '|' or any whitespace character */ > ... > So, any "digit' name (e.g. "my:777") sould be valid. > WHAT I DO: > import org.apache.jackrabbit.core.query.*; > ... > String q = "/jcr:root / 2 / ( *, mytype)"; > QueryParser.parse( q, "xpath", nsRegistry); > WHAT I EXPECT TO HAVE: > Succesfully parsed query. > WHAT I GET: > javax.jcr.query.InvalidQueryException: Parse error: data is not a > RelationQueryNode > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:434) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:79) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:88) > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:469) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:79) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:88) > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:469) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:79) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:88) > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:469) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:79) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:88) > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:469) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:79) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:88) > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:469) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:79) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:88) > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:469) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:79) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:88) > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:469) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:79) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:88) > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.createPathQueryNode(XPathQueryBuilder.java:612) > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:317) > at > org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:79) > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.<init>(XPathQueryBuilder.java:244) > at > org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.createQuery(XPathQueryBuilder.java:275) > at > org.apache.jackrabbit.core.query.xpath.QueryBuilder.createQueryTree(QueryBuilder.java:36) > at > org.apache.jackrabbit.core.query.QueryParser.parse(QueryParser.java:53) > ... > P.S.
