A warning to all PHP programmer using this function PHP 5.0.0.0: We needed an equivalent to upper-case() function (is not available in XPath 1.0).
XML-Document:
<Rec>
<SourceRef>./c:calendar2</SourceRef>
<SourceRef>./c:calendar</SourceRef>
</Rec>
using
query('//DataStore[translate(SourceRef,"abcdefghijklmnopqrstuvwxyz","ABCDEFGHIJKLMNOPQRSTUVWXYZ")="./C:CALENDAR"]/.')
returns ZERO matches.
If you change XML-Source to
<Rec>
<SourceRef>./c:calendar</SourceRef>
<SourceRef>./c:calendar2</SourceRef>
</Rec>
everything works fine
