把所有的数据当做一个字符串

收到数据后先strstr(buffer,"<?xml version=\"1.0\" encoding=\"UTF-8\"?>")

如果返回的是NULL则表示没有这段 退出

buffer是你收到的数据起始地址

我上次才给人写过

xml文件内容

<?xml version="1.0" encoding="UTF-8" ?>

- <aicomoa_response>

- <country_list>

- <country>

<id>7</id>

<pid>0</pid>

<continent_id>1</continent_id>

<guohao>93</guohao>

<cntitle>阿富汗</cntitle>

<entitle>Afghanistan</entitle>

<hztitle>阿富汗</hztitle>

<jptitle>アフガニスタン</jptitle>

<kotitle>??????</kotitle>

<jp_pinyin>ア</jp_pinyin>

<pinyin>AFuHan</pinyin>

<sid>0</sid>

<jibie>1</jibie>

</country>

- <country>

<id>8</id>

<pid>0</pid>

<continent_id>2</continent_id>

<guohao>355</guohao>

<cntitle>阿尔巴尼亚</cntitle>

<entitle>Albania</entitle>

<pinyin>AErBaNiYa</pinyin>

</country>

</country_list>

运行结果

Info[0]=[id:7|pid:0|continent_id:1|guohao:93|cntitle:阿富汗|entitle:Afghanistan|

hztitle:阿富汗|jptitle:アフガニスタン|kotitle:??????|jp_pinyin:ア|pinyin:AFuHan|

补充：你这个就说得太笼统了，

1 你上传的xml文件具体格式是什么？

2 要在网页上显示的具体格式是什么

3 你根本不知道怎么做 所以也不知道怎么问

我不用关心你的c语言的cgi吧？我才不管是用什么上传的

只有你说的嵌入式三个字 给我一点有用信息 就是解析这个xml用插件恐怕是不行

只能C语言

4 我现在只要求你的xml文件格式和 网页上要显示哪些xml中解析出来的信息

只要知道这些 我只需要在我的程序上加上生成html文件就行了
