. NET general operations for XML

For directly creating an XML file this, skip directly. Assume that the initial content of the XML is the following side:

<? XML version= "1.0" ?> < Conf > </ Conf >

Where the root node is CONF.

Adding nodes

 Public Static BOOLaddconfig (Commonconfig conf) {Try{XmlDocument doc=NewXmlDocument (); Doc.                Load (Configpath); XmlElement Root=Doc.                DocumentElement; XmlElement Body= Doc. CreateElement ("Config"); XmlElement commoncontent= Doc. CreateElement ("commoncontent"); Commoncontent.innertext=conf.commoncontent; XmlElement commonpriority= Doc. CreateElement ("commonpriority"); Commonpriority.innertext=conf.CommonPriority.ToString (); Body.                AppendChild (commoncontent); Body.                                AppendChild (commonpriority); XmlAttribute Attr= Doc. CreateAttribute ("CommonName"); Attr.innertext=Conf.commonname; Body.                Attributes.append (ATTR); Root.                AppendChild (body); Doc.                Save (Configpath); return true; }            Catch(Exception ex) {Logmsg.writelog ("General Configuration Add configuration information exception:"+Ex.                ToString ()); return false; }        }        #endregion

Edit Node

 Public Static BOOLmodifyconfig (Commonconfig conf) {Try{XmlDocument doc=NewXmlDocument (); Doc.                Load (Configpath); XmlElement Root=Doc.                DocumentElement; XmlNode Commoncontentnode= root. selectSingleNode ("/conf/config[@CommonName = '"+ Conf.commonname +"']/commoncontent"); Commoncontentnode.innertext=conf.commoncontent; //because the attribute commonname is used to determine the node, the modified action is placed at the end, otherwise the child node will not getXmlNode Confnode = root. selectSingleNode ("/conf/config[@CommonName = '"+ Conf.commonname +"']"); confnode.attributes["CommonName"]. Value =Conf.                Newcommonname; Doc.                Save (Configpath); return true; }            Catch(Exception ex) {Logmsg.writelog ("Common Configuration Modify configuration information exception:"+Ex.                ToString ()); return false; }        }

Get all nodes

 Public StaticList<commonconfig>Getallconfig () {List<CommonConfig> listconf =NewList<commonconfig>(); stringCacheKey ="Commonconfig_cache"; System.Web.Caching.Cache Objcache=Httpruntime.cache; if(Objcache[cachekey] = =NULL) {XmlDocument doc=NewXmlDocument (); Doc.                Load (Configpath); XmlElement Root=Doc.                DocumentElement; XmlNodeList NodeList=Root.                ChildNodes; foreach(XmlNode CurnodeinchnodeList) {Commonconfig conf=NewCommonconfig (); Conf.commonname= curnode.attributes["CommonName"].                    Value; XmlNode Contentnode=curnode.selectsinglenode ("commoncontent"); Conf.commoncontent=Contentnode.innertext; XmlNode Prioritynode= Curnode.selectsinglenode ("commonpriority"); Conf.commonpriority=Convert.ToInt32 (Prioritynode.innertext);                Listconf.add (conf); } System.Web.Caching.CacheDependency DEP=NewSystem.Web.Caching.CacheDependency (Configpath);                Datacache.setcache (CacheKey, listconf, DEP); returnlistconf; }            Else            {                returnObjcache[cachekey] asList<commonconfig>; }        }

The end result is this:

<?XML version= "1.0"?><Conf>  <ConfigCommonName= "website logo">    <commoncontent>Website logo</commoncontent>    <commonpriority>1</commonpriority>  </Config></Conf>

The above need to use the XPath syntax, I also can not remember, so put a link here, later used to go to see on the line.

You might want to add some operations to the XML later ...
