For direct access, we want to have a button that will validate the current document. The method is similar to that used in the previous section.
First comes the button:
<input type="button" value="Validate" onclick="BtnValidate()">
|
Then we provide the script that will validate the current document.
// ----------------------------------------------------------------------
// check validity of current document.
// if validation fails, show validation result in alert box .
function BtnValidate()
{
// get top-level object of automation interface
var objApp = objXMLSpyControl.Application;
// get the active document
var objDocument = objApp.ActiveDocument;
if ( objDocument == null )
alert( "no active document found" );
else
{
// define as arrays to support their usage as return parameters
var errorText = new Array(1);
var errorPos = new Array(1);
var badData = new Array(1);
var valid = objDocument.IsValid(errorText, errorPos, badData);
if (! valid)
{
// compose the error description
var text = errorText;
// access that XMLData object only if filled in
if (badData[0] != null)
text += "(" + badData[0].Name + "/" + badData[0].TextValue + ")";
alert("Validation error[" + errorPos + "]: " + text);
}
else
alert("Document is valid");
}
}
