XdmValue.toString() for SaxonJ versus XdmValue::toString for SaxonC
Added by Martin Honnen almost 3 years ago
Is it an intended difference between SaxonJ and SaxonC (tested with 11.1 in both cases) that the toString()
method on XdmValue
in the Java case outputs a newline/linebreak as a separator between the items in the XdmValue while for SaxonC and C++ the ->toString()
gives a long line with all items' serialization concatenated without any separator? Both API documentations talk about adpative serialization of the sequence/XdmValue being used.
So while Java
Processor processor = new Processor(true);
XdmValue results = processor.newXPathCompiler().evaluate("1, 'string', true(), parse-xml-fragment(string-join((1 to 3) ! ('<item>' || . || '</item>')))/node(), array { 1 to 5 }, map { 'key1' : 1, 'key2' : 'foo' }", null);
System.out.println(results.toString());
gives several readable lines of outputs:
1
"string"
true()
<item>1</item>
<item>2</item>
<item>3</item>
[1,2,3,4,5]
map{"key1":1,"key2":"foo"}
C++ meanwhile
XdmValue * resultValues = xpath->evaluate("1, 'string', true(), parse-xml-fragment(string-join((1 to 3) ! ('<item>' || . || '</item>')))/node(), array { 1 to 5 }, map { 'key1' : 1, 'key2' : 'foo' }");
if(resultValues == nullptr) {
printf("result is null \n");
SaxonApiException * exception = xpath->getException();
if(exception != nullptr) {
const char *message = xpath->getErrorMessage();
cout << "Error Message = " << message << endl;
xpath->exceptionClear();
}
sresult->failure++;
sresult->failureList.push_back("testXPathValues2");
} else {
cout<<"Number of items="<<resultValues->size()<<endl;
cout<<"toString()="<<resultValues->toString()<<endl;
gives a long, hard to read line of all items concatenated without any separator:
Number of items=8
toString()=1stringtrue<item>1</item><item>2</item><item>3</item>[1,2,3,4,5]map{"key1":1,"key2":"foo"}
This also trickles down to the Python API where the print(somePyXdmValue)
also shows a long line without any item separator.
It is kind of hard to read the C++ or Python result, can it be improved to use an item separator, like Java seems to do?

It is not intended for the XdmValue.toString()
to be different in SaxonC and SaxonJ. SaxonC constructs the string from the individual XdmItems in the C++ code. I will look at aligning the output of SaxonC with SaxonJ.

I hope to add a patch to this issue in the next maintenance release. Bug issue added: #5305
