<div><p>When validating XPCML schema documents, a fully validating XML
|
||
|
|
parser may generate warnings, non-fatal parse errors, and fatal parse errors.</p>
|
||
|
|
<div class="section"><p>Warnings and non-fatal parse errors do not cause the parse
|
||
|
|
to fail. You might want to examine warnings and non-fatal errors to help you
|
||
|
|
determine problems with your XPCML source. Fatal parse errors cause the parse
|
||
|
|
to terminate with an exception.</p>
|
||
|
|
<p>To display warnings and non-fatal parser
|
||
|
|
errors when parsing an XPCML document, turn tracing on in your application
|
||
|
|
and set the trace category to PCML.</p>

<div class="section"><h4 class="sectiontitle">Example</h4><p>A fully validating XML parser generates
|
||
|
|
an error for any numeric parameter type that does not have a value. The following
|
||
|
|
example shows sample XPCML source and the resulting non-fatal parse error:</p>
|
||
|
|
<p><strong>XPCML

||
|
|
source</strong></p>
|
||
|
|
<pre> <program name="prog1"/>

<parameterList>
|
||
|
|
<intParm name="parm1"/>
|

</parameterList>

</program></pre>
|
||
|
|
<p><strong>Resulting error</strong></p>
|
||
|
|
<pre> Tue Mar 25 15:21:44 CST 2003 [Error]: cvc-complex-type.2.2: Element
|
||
|
|
'intParm' must have no element [children], and the value must be valid.</pre>
|
||
|
|
<p>To
|
||
|
|
prevent logging this kind of error, add the nil=true attribute to the intParm
|
||
|
|
element. The nil=true atttribute signals to the parser that you have deliberately
|
||
|
|
left the element empty.. Here is the previous XPCML source with the nil=true
|
||
|
|
atttribute added:</p>
