7 Error in XPath string function - ID: 2187949

Last Update: Settings changed ( peterw8102 )

Details:

Thanks to William Vambenepe (Oracle) for spotting this.

The bug is best illustrated in the Whitebeam web-site XPath test-bed.
Execute the XPath expression :
string(/parent/child/@id)

on the default document. The node-set within the string function will
contain three nodes. According to the XPath spec, the 'strong()' function
on a NodeSet should return the string value of the first node in the set
(in document order). Whitebeam currently takes the value of the *last*
node.

Date: 2008-10-22 23:45 Sender: peterw8102 common/XPath/XmlPathUtils.cxx contains the CrbXmlElementSet::ToString method. This loops through the NodeSet looking for the first non-NULL node. Having found the node it should then convert that to a string then exit the loop. Instead it continues until all nodes are processed, writing the string value of each to the output string. Fixed with a 'break' after extracting the first string.

Having found the node it should then convert that to a string *then* exit
the loop. Instead it continues until all nodes are processed, writing the
