[jira] Resolved: (JCR-829) XPath character escape problem

Posted by "Marcel Reutegger (JIRA)" <ji...@apache.org>.

     [ https://issues.apache.org/jira/browse/JCR-829?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Marcel Reutegger resolved JCR-829.
----------------------------------

    Resolution: Invalid

The space and ampersand are illegal characters in an XML name. You need to encode them as described in section 6.4.3 of the JSR 170 specification.

//a_x0020__x0026__x0020_b

will work.
