CMarkup解析XML获得IP的问题

沧海1梦 2016-09-30 10:17:21

<cameras>

	<camera ip="192.127.66.98" id="b16f71e0-ffff-ffff-bf36-9d863ee5445" status="0" hasptz="0"/>

	<camera ip="192.127.66.99" id="b16f71e0-ffff-ffff-bf36-9d863ee5446" status="0" hasptz="0"/>

	<camera ip="192.127.66.100" id="b16f71e0-ffff-ffff-bf36-9d863ee5447" status="0" hasptz="0"/>

</cameras>

我的xml文件如上所示，我想解析得到所有的ip和id信息，现在只实现了获取单个ip和id 的信息，

strip=xml.GetChildAttrib("ip");

			strid=xml.GetChildAttrib("id");

			xml.FindChildElem( "ip" );

			cout<<"strip="<<strip<<endl;

			cout<<"strid="<<strid<<endl;

			xml.OutOfElem();

请大家帮我看看，提供一些思路，不胜感激。

[quote=引用 9 楼 lianshaohua 的回复:] http://www.firstobject.com/fast-start-to-xml-in-c++.htm 这个网页在底部有详细的使用：


To find the item with a particular serial number, you can loop through the ITEM elements and compare the SN element data to the serial number you are searching for. By specifying the "ITEM" element tag name in the FindElem method we ignore all other sibling elements such as the SHIPMENT element. Also, instead of going into and out of the ITEM element to look for the SN child element, we use the FindChildElem and GetChildData methods for convenience.

xml.ResetPos(); // top of document
xml.FindElem(); // ORDER element is root
xml.IntoElem(); // inside ORDER
while ( xml.FindElem("ITEM") )
{
    xml.FindChildElem( "SN" );
    if ( xml.GetChildData() == strFindSN )
        break; // found
}

CMarkup xml;
    //bool flag;
	xml.Load(_T("F:\\1.xml"));
	xml.ResetMainPos();
	string strFindcamera;
	//xml.FindElem();
	//xml.IntoElem();   //进入根节点
	while (xml.FindElem("cameras"))
	{
		xml.FindChildElem("camera");
		if (xml.GetChildData()==strFindcamera)
		{		
				string strip;
				string strid;
				strip=xml.GetChildAttrib("ip");
				strid=xml.GetChildAttrib("id");
				g_CameraInfo.insert(pair<string,string>(strip,strid));		
		}

	}

版主，再次打扰你下，我看了那个网站，然后写了上面的代码，但现在还是只能获取单个IP和ID，循环一次就断了，最近才用这个，恳请版主空闲的时候帮我看看，不甚感激！谢谢版主！[/quote] 你运行一下他的例子，看有没有问题

首先获取cameras结点所有子结点的集合，然后再遍历取得，都有对应的方法

谢谢版主，这方面还是小白，我再找找
