xml如何解析一个变量，不是文件

[peterspace]

this_page.php
$xml_temp_string被form提交过来到这个页面，
以前解析一个文件的代码，我会简单组织编写，如下：
...
$parser = xml_parser_create();
xml_set_element_handler($parser, "startElement", "endElement");
xml_set_character_data_handler($parser, "characterData");
if (!($filehandler = fopen($xml_file, "r"))) { die("could not open XML input"); }
while ($data = fread($filehandler, 4096))
{ if (!xml_parse($parser, $data, feof($filehandler)))
{ die(sprintf("XML error: %s at line %d",
xml_error_string(xml_get_error_code($parser)),
xml_get_current_line_number($parser)));
}
}
fclose($filehandler); xml_parser_free($parser);
...
运行正常。
但现在要解析一个变量，修改如下：
$parser = xml_parser_create();
xml_set_element_handler($parser, "startElement", "endElement");
xml_set_character_data_handler($parser, "characterData");
xml_parse($parser, $xml_temp_string, true);
xml_parser_free($parser);
调试不能通过。
烦！请哪位高手，拔笔相助！

形如<resultfields id=\"1\">的节点肯定是错了
应该是<resultfields id="1">

你有两颗星星！果然有两下子。
那怎么办？
原文本来也是没有被转义的： ...<resultfields id="1 ">...
但提交过来后就变了，怎么办？


上个页面中提交前的javascript代码：
function checkseries(m,seriesname)
{
var xmlhttp=new ActiveXObject("Msxml2.xmlhttp");
xmlhttp.open("GET","http://62.173.95.224/xmla/dll_results.asp?m="+m+"&CID=apasin&DBM=trial&FIELDS=default,jacket&ST_01="+seriesname+"&SF_01=series",false);
xmlhttp.send();
document.formseries.seriestext.innerText = xmlhttp.ResponseText;
document.formseries.submit();
return true;
}

$xml_temp_string = StripSlashes($xml_temp_string);

也可关闭magic_quotes_gpc开关
1、php.ini中
magic_quotes_gpc=off

2、接收表单的程序中
if(get_magic_quotes_gpc() == 1)
set_magic_quotes_gpc(0);

php.ini的设置是不是可以随便改的？我是用www.51.net网站的空间。
好烦！
不行啦，不做这个项目，我拿着工资回家过年去，上海不好玩。

$xml_temp_string
的内容是什么？

你echo出来看看~~~

还有表单提交过来的应该用$_POST["..."]
不知道是不是你前面给$xml_temp_string赋$_POST["..."]值了？

[xuzuning]

请确保$xml_temp_string的内容是合法的xml格式

在this_page中echo $xml_temp_string
