[jira] Commented: (JCR-1248) Helper Method to escape illegal XPath Search Term

["Paco Avila (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JCR-1248?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12839819#action_12839819 ] 

Paco Avila commented on JCR-1248:
---------------------------------

A query like this will fail:

//element(*, nt:base)[jcr:contains(., 'test[')]

Specification JSR-170 at point 6.6.5.2 says that literal instances like single quote ( ' ), double quote ( " ) and hyphen ( - ) must be escaped with a backslash ( \ ), and backslash itself should be escaped as a double backslash ( \\ ). Also, I have noted that some chars like [ and ] need to be escaped also.
