j-users, When running the following XSL file Xalan-J 2.7.1 throws java.lang.StringIndexOutOfBoundsException: String index out of range: 0 - String index out of range: 0 As long as the root node does not have an attribute named "anAttribute".
Expected output is an single root node https://xalan.apache.org/xalan-j/apidocs/org/apache/xalan/lib/ExsltDatetime.html#date(java.lang.String) indicates that it should produce an empty string instead of throwing "If the argument is not in either of these formats, date:date returns an empty string ('')" Saxon produces the expected. output If the null check where moved to the start of the date function it world work as specified. <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:exsl="http://exslt.org"; xmlns:date="http://exslt.org/dates-and-times"; extension-element-prefixes="date exsl" version="1.0"> <xsl:template match="/"> <xsl:element name="root"> <xsl:value-of select="date:date(@anAttribute)"/> </xsl:element> </xsl:template> </xsl:stylesheet> Is this a bug? Should I write it up? Thanks, Philip Miess
