php解析xml在5.2版本环境报错，5.3版本正常。
if (isset($_post['xmldata'])) {
$string=.$_post['xmldata'].;
$doc=$xml = new domdocument();
$xml->loadxml($string);
...
为什么我表单提交过来的xml文件，页面报错呢？
页面提示信息：
warning: domdocument::loadxml() [domdocument.loadxml]: attvalue: or ' expected in entity, line: 2 in /usr/local/apache2/htdocs/dbmanage/xmlfile.php on line 126
warning: domdocument::loadxml() [domdocument.loadxml]: attributes construct error in entity, line: 2 in /usr/local/apache2/htdocs/dbmanage/xmlfile.php on line 126

xml格式如下：
php版本：
#php -v
php 5.2.12 (cli) (built: apr 25 2012 21:12:31)
------解决方案--------------------
var_dump($string); // 加上这句，贴出结果来。
$xml->loadxml($string);
------解决方案--------------------
表单post上来的？enctype是什么? 还是ajax提上来的？ content-type设置了什么？ 看看http_raw_post_data？
