XQueryParseException

Exception thrown when XQuery parsing fails due to syntax errors in the source text.

#XQueryParseException

Namespace: PhoenixmlDb.XQuery.Parser

Exception thrown when XQuery parsing fails due to syntax errors in the source text.

This exception is thrown by XQueryParserFacade.Parse when the input contains one or more syntax errors. The XQueryParseException.Errors property provides structured error information including line and column numbers for each error.

To avoid exceptions for expected invalid input, use XQueryParserFacade.TryParse instead, which returns errors through an out parameter.

#Example

csharp

try
{
    var ast = parser.Parse("for $x in (1,2,3) return");  // missing return expression
}
catch (XQueryParseException ex)
{
    foreach (var error in ex.Errors)
        Console.Error.WriteLine($"Line {error.Line}, Column {error.Column}: {error.Message}");
}
