hi, i'm using requestbuilder to communicate with php.
i used a XMLWriter to place the sql result in xml:
$writer = new XMLWriter();
$writer->openMemory();
$writer->startDocument('1.0', 'UTF-8');
$writer->setIndent(4);
$writer->startElement("result");
for($row = 0; $rowdata = mysql_fetch_array($result); $row++){
$writer->startElement("row");
$writer->writeAttribute("index", $row);
for($col = 0; $col < count($rowdata)/2; $col++){
$writer->startElement("column");
$writer->writeAttribute("index", $col);
$writer->text($rowdata[$col]);
$writer->endElement();
}
$writer->endElement();
}
$writer->endElement();
$writer->endDocument();
echo $writer->outputMemory();
when i view it in a browser it perfectly fine, this is the page source
content:
<?xml version="1.0" encoding="UTF-8"?>
<result>
<row index="0">
<column index="0">1</column>
<column index="1">abc</column>
<column index="2">123</column>
</row>
<row index="1">
<column index="0">2</column>
<column index="1">def</column>
<column index="2">456</column>
</row>
<row index="2">
<column index="0">3</column>
<column index="1">ghi</column>
<column index="2">789</column>
</row>
</result>
it looks fine. but when i try to get the data using request builder
and use Window.alert:
RequestBuilder builder = new RequestBuilder(RequestBuilder.POST,
script);
builder.setHeader("Content-Type", "application/x-www-form-
urlencoded");
builder.sendRequest("", new RequestCallback() {
public void onResponseReceived(Request request, Response response)
{
Window.alert(response.getText());
}
public void onError(Request request, Throwable exception) {
Window.alert("Error: " + exception.toString());
}
});
the output i get is:
<?xml version="1.0" encoding="UTF-8"?>
<result/>
any idea what happened to the content of the document?
i even tried to make the script simple:
$output = "";
$output = $output . '<?xml version="1.0" encoding="UTF-8"?>';
$output = $output . '<result>';
for($row = 0; $rowdata = mysql_fetch_array($result); $row++){
$output = $output . '<row index="' . $row .'">';
for($col = 0; $col < count($rowdata)/2; $col++){
$output = $output . '<column index="' . $col .'">';
$output = $output . $rowdata[$col];
$output = $output . '</column>';
}
$output = $output . '</row>';
}
$output = $output . '</result>';
echo $output;
i get the correct output in php but i still get the same empty
document
in the response
