5.检查XML是否有效
<?php
//创建XML解析器
$xml_parser = xml_parser_create();
//使用大小写折叠来保证能在元素数组中找到这些元素名称
xml_parser_set_option($xml_parser, XML_OPTION_CASE_FOLDING, true);
//读取XML文件
$xmlfile = "bb.xml";
if (!($fp = fopen($xmlfile, "r")))
{
die("无法读取XML文件$xmlfile");
}
//解析XML文件
$has_error = false; //标志位
while ($data = fread($fp, 4096))
{
//循环地读入XML文档，只到文档的EOF，同时停止解析
if (!xml_parse($xml_parser, $data, feof($fp)))
{
$has_error = true;
break;
}
}
if($has_error)
{
echo "该XML文档是错误的！<br />";
//输出错误行，列及其错误信息
$error_line = xml_get_current_line_number($xml_parser);
$error_row = xml_get_current_column_number($xml_parser);
$error_string = xml_error_string(xml_get_error_code($xml_parser));
$message = sprintf("［第%d行，%d列］：%s",
$error_line,
$error_row,
$error_string);
echo $message;
}
else
{
echo "该XML文档是结构良好的。";
}
//关闭XML解析器指针，释放资源
xml_parser_free($xml_parser);
?>
6.可用于精确的读取XML
test.xml
<?xml version="1.0" encoding="UTF-8" ?>
<SBMP_MO_MESSAGE>
<CONNECT_ID>100</CONNECT_ID>
<MO_MESSAGE_ID>123456</MO_MESSAGE_ID>
<RECEIVE_DATE>20040605</RECEIVE_DATE>
<RECEIVE_TIME>153020</RECEIVE_TIME>
<GATEWAY_ID>1</GATEWAY_ID>
<VALID>1</VALID>
<CITY_CODE>010</CITY_CODE>
<CITY_NAME>北京</CITY_NAME>
<STATE_CODE>010</STATE_CODE>
<STATE_NAME>北京</STATE_NAME>
<TP_PID>0</TP_PID>
<TP_UDHI>0</TP_UDHI>
<MSISDN>15933626501</MSISDN>
<MESSAGE_TYPE>8</MESSAGE_TYPE>
<MESSAGE>5618常年供应苗木，品种有玉兰、黄叶杨等。联系人：张三，电话：1234567890。</MESSAGE>
<LONG_CODE>100</LONG_CODE>
<SERVICE_CODE>9588</SERVICE_CODE>
</SBMP_MO_MESSAGE>
test.php:
<?php
$myData = array();

if(strpos($file, '<?xml') > -1) {
try {

if($xml) {

//获取节点值
$CONNECT_ID = $xml->CONNECT_ID;
$MO_MESSAGE_ID = $xml->MO_MESSAGE_ID;

$MSISDN = $xml->MSISDN;
$MESSAGE_TYPE = $xml->MESSAGE_TYPE;
