解析xml文件的郁闷问题

[epeoer]

这是我的xml文件内容
<?xml version="1.0" encoding="UTF-8"?>
<sitech-version-manager>
<!-- -->
<system name="name1">
<watch-path>/score/verman</watch-path>
<watch-path>/home/b</watch-path>
<watch-path>/home/c</watch-path>
<watch-path>/home/d</watch-path>
<watch-path>/home/e</watch-path>
</system>
<system name="name2">
<watch-path>/home/a</watch-path>
<watch-path>/home/b</watch-path>
<watch-path>/home/c</watch-path>
<watch-path>/home/d</watch-path>
<watch-path>/home/e</watch-path>
</system>
<system name="name3">
<watch-path>/home/a</watch-path>
<watch-path>/home/b</watch-path>
<watch-path>/home/c</watch-path>
<watch-path>/home/d</watch-path>
<watch-path>/home/e</watch-path>
</system>
<dbcfg>
<url>aaaaaaaaaa</url>
<username>/home/c</username>
<password>/home/d</password>
<name>/home/e</name>
</dbcfg>
</sitech-version-manager>

这是我的解析程序
#include <libxml/xmlmemory.h>

问题： 关于dbcfg下面的所有东西都解析不出来

[tailzhou]

sprintf(dbcfgPnt->url,key,sizeof(key));
格式错误！！

sprintf(dbcfgPnt->url,"%s",key);

[jixingzhong]

看你其他散 sprintf 不都是正确的么...

楼主改过来上面的错误吧

[tailzhou]

不过不应该是sprintf的问题。
memset(dbcfgPnt,0x0,sizeof(dbcfgPnt)); //这里初试化也有点问题；
memset(dbcfgPnt,0x0,sizeof(dbcfg));
你的dbcfg 的定义？？

你的printf打印出来的信息？parseSys是否能正常读取？

libxml没用过,
一直只用过Apache的xerces-c
