The code below

 
IEnumerator Date_SingleSIOPropertySave (string SIOName Dictionary ValueDic) 
{
//first traversal root xmlnode target node 
XmlNode lookForNode=null; 
Foreach (XmlNode item in currnetSIOXml. FirstChild..childnodes) 
{
The if (item Name==SIOName) 
{
LookForNode=item; 
break; 
} 
} 
Yield return 0; 
//find the target entry after traversal entry under the properties of the entry 

Foreach (XmlNode child in lookForNode..childnodes) 
{
//traverse a property would traverse a dictionary key to find corresponding key attribute node and at the end of the processing time of break end cycle 
Foreach (var Key in valueDic. Keys) 
{
If (Key==child. Name) 
{
XmlElement newProperty=currnetSIOXml. The CreateElement method (Key); 
LookForNode. ReplaceChild (newProperty, child); 
break; 
} 
} 
} 
}
