3659 | *
|
---|
3660 | * Patternist is designed to do all name resolution at parse time so the subsequent code only has to
|
---|
3661 | * deal with expanded QNames(which the QName class represents), and this presents a problem since
|
---|
3662 | * the parser haven't even encountered the @c xmlns:prefix when resolving @c prefix in the name test.
|
---|
3663 | *
|
---|
3664 | * This is solved as follows:
|
---|
3665 | *
|
---|
3666 | * <ol>
|
---|
3667 | * <li>Just before starting parsing the attributes, we call Tokenizer::commenceScanOnly().
|
---|
3668 | * This switches the tokenizer to not tokenize embedded expressions in attributes,
|
---|
3669 | * but to return them as strings, token type STRING_LITERAL.</li>
|
---|
3670 | * <li>We parse all the attributes, and iterates over them, only caring about
|
---|
3671 | * namespace bindings, and validates and adds them to the context.</li>
|
---|
3672 | * <li>We call Tokenizer::resumeTokenizationFrom() from the previous position
|
---|
3673 | * returned from Tokenizer::commenceScanOnly() and parses the attributes once more,
|
---|
3674 | * but this time with tokenization of embedded expressions. Since we this time
|
---|
3675 | * have the namespace bindings in place, everything resolves.</li>
|
---|
3676 | * </ol>
|
---|
3677 | *
|
---|
3678 | * Saxon does this in a similar way. Study net.sf.saxon.expr.QueryParser::parseDirectElementConstructor().
|
---|
