XML文档:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <array>
    <dict>
      <key>name</key> <string>名字</string>
    </dict>
  </array>
</plist>

解析:

ValueVector p_map = FileUtils::getInstance()->getValueVectorFromFile(xml Flie);  

ValueMap  map=p_map.at(0).asValueMap();

string str=map.at("name").asString();

使用过程中没有问题 希望对你有帮助

======== 文档开头是array的要用ValueVector接收，是Dict开头的采用ValueMap接收
