|

| 52 | The QXmlErrorHandler class provides an interface to report
|
|---|
| 53 | errors in XML data.
|
|---|
| 54 |
|
|---|
| 55 | <p>
|
|---|
| 56 |
|
|---|
| 57 | <p> If you want your application to report errors to the user or to
|
|---|
| 58 | perform customized error handling, you should subclass this class.
|
|---|
| 59 | <p> You can set the error handler with <a href="qxmlreader.html#setErrorHandler">QXmlReader::setErrorHandler</a>().
|
|---|
| 60 | <p> Errors can be reported using <a href="#warning">warning</a>(), <a href="#error">error</a>() and <a href="#fatalError">fatalError</a>(),
|
|---|
| 61 | with the error text being reported with <a href="#errorString">errorString</a>().
|
|---|
| 62 | <p> See also the <a href="xml.html#sax2Intro">Introduction to SAX2</a>.

|

| 68 |
|
|---|
| 69 | <p> A reader might use this function to report a recoverable error. A
|
|---|
| 70 | recoverable error corresponds to the definiton of "error" in
|
|---|
| 71 | section 1.2 of the XML 1.0 specification. Details of the error are
|
|---|
| 72 | stored in <em>exception</em>.
|
|---|
| 73 | <p> The reader must continue to provide normal parsing events after
|
|---|
| 74 | invoking this function.
|
|---|
| 75 | <p> If this function returns FALSE the reader stops parsing and
|
|---|
| 76 | reports an error. The reader uses the function <a href="#errorString">errorString</a>() to
|
|---|
| 77 | get the error message.
|
|---|
| 78 |
|

| 79 | <h3 class=fn><a href="qstring.html">QString</a> <a name="errorString"></a>QXmlErrorHandler::errorString ()<tt> [pure virtual]</tt>
|
|---|
| 80 | </h3>
|
|---|
| 81 |
|
|---|
| 82 | <p> The reader calls this function to get an error string if any of
|
|---|
| 83 | the handler functions returns FALSE.
|
|---|
| 84 |
|
|---|
| 85 | <h3 class=fn>bool <a name="fatalError"></a>QXmlErrorHandler::fatalError ( const <a href="qxmlparseexception.html">QXmlParseException</a> & exception )<tt> [pure virtual]</tt>
|
|---|
| 86 | </h3>
|
|---|
| 87 |
|
|---|
| 88 | <p> A reader must use this function to report a non-recoverable error.
|
|---|
| 89 | Details of the error are stored in <em>exception</em>.
|
|---|
| 90 | <p> If this function returns TRUE the reader might try to go on
|
|---|
| 91 | parsing and reporting further errors; but no regular parsing
|
|---|
| 92 | events are reported.
|
|---|
| 93 |
|
|---|
| 94 | <h3 class=fn>bool <a name="warning"></a>QXmlErrorHandler::warning ( const <a href="qxmlparseexception.html">QXmlParseException</a> & exception )<tt> [pure virtual]</tt>
|
|---|
| 95 | </h3>
|
|---|
| 96 |
|
|---|
| 97 | <p> A reader might use this function to report a warning. Warnings are
|
|---|
| 98 | conditions that are not errors or fatal errors as defined by the
|
|---|
| 99 | XML 1.0 specification. Details of the warning are stored in <em>exception</em>.
|
|---|
| 100 | <p> If this function returns FALSE the reader stops parsing and
|
|---|
| 101 | reports an error. The reader uses the function <a href="#errorString">errorString</a>() to
|
|---|
| 102 | get the error message.
