Description

« Hide

When I load an XML document whose elements contain attributes with URIs as values, the Laszlo XPath implementation can't match the element with "elementName[@attrName='URI']" unless the URI doesn't contain any forward slashes (which never happens). This is a _big_ issue when using Semantic Web technologies, where all 'object ids' are actually URIs.

See the attached urlXPathProblem.lzx file for a test case.

testcase does not work, string literal can start with a single-quote or a double-quote!
