Question

我在将数据插入MySQL数据库时使用mysql_real_escape_string函数。我正在

“结束标记'test_field'与开始标记'结束'不匹配。错误处理资源“

生成XML时。它看起来像特殊字符或小于或大于导致此问题的符号。这是我的代码。如果有任何建议，请告诉我。

这是PHP代码。

$result = mysql_query("SELECT * from table1");

header("Content-Type: application/xml");
echo sqlToXml($result, "SalesOrder", "sales");

function sqlToXml($queryResult, $rootElementName, $childElementName)
{

$xmlData = "<?xml version=\"1.0\" encoding=\"ISO-8859-1\" ?>\n"; 
$xmlData .= "<" . $rootElementName . ">";

while($record = mysql_fetch_object($queryResult))
{ 
    $xmlData .= "<" . $childElementName . ">";
    for ($i = 0; $i < mysql_num_fields($queryResult); $i++)
    { 
        $fieldName = mysql_field_name($queryResult, $i); 
        $xmlData .= "<" . $fieldName . ">";
        if(!empty($record->$fieldName))
            $xmlData .= $record->$fieldName; 
        else
            $xmlData .= "null"; 

        $xmlData .= "</" . $fieldName . ">"; 
    } 

        $detail = mysql_query("SELECT * from table2 WHERE salesordernumber = '".$record->SalesOrderNumber."'");
while ($row = mysql_fetch_object($detail)) { 
   $xmlData .= "<Details>";
   $xmlData .= "<SalesOrderDetailID>" . $row->SalesOrderDetailID . "</SalesOrderDetailID>";
   $xmlData .= "<Name>" . $row->Name . "</Name>";
   $xmlData .= "<CarrierTrackingNumber>" . $row->CarrierTrackingNumber . "</CarrierTrackingNumber>";
   $xmlData .= "</Details>";
}



    $xmlData .= "</" . $childElementName . ">"; 
} 
$xmlData .= "</" . $rootElementName . ">"; 
}

我建议使用PHP XMLWriter来生成XML。您可以使用它轻松生成有效的XML文件，并且它更具可读性：

function sqlToXml($queryResult, $rootElementName, $childElementName) {
    $w = new XMLWriter();
    $w->openMemory();
    $w->setIndent(true);
    // use tabs as indents
    $w->setIndentString("   ");
    $w->startDocument("1.0", 'ISO-8859-1');
    $w->startElement($rootElementName);

    while($record = mysql_fetch_object($queryResult)) {
        $w->startElement($childElementName);
        for ($i = 0; $i < mysql_num_fields($queryResult); $i++) { 
            $fieldName = mysql_field_name($queryResult, $i); 
            $w->startElement($fieldName);
            if(!empty($record->$fieldName)) {
                $w->writeCData($record->$fieldName);
            }
            else {
                $w->writeCData("null");
            }
            $w->endElement(); // $fieldName
        } 
        $w->endElement(); // $childElementName
    } 
    $w->endElement(); // $rootElementName
    $w->endDocument();
    return $w->outputMemory();
}
