我试图理解需要使用一些VB.net代码写入数据库的XML的大数据转储。我正在寻找解析代码入门的一些帮助,特别是如何访问属性值。用VB.net解析XML
<Product ID="523233" UserTypeID="Property" ParentID="523232">
<Name>My Property Name</Name>
<AssetCrossReference AssetID="173501" Type=" Non Print old">
</AssetCrossReference>
<AssetCrossReference AssetID="554740" Type=" Non Print old">
</AssetCrossReference>
<AssetCrossReference AssetID="566495" Type=" Non Print old">
</AssetCrossReference>
<AssetCrossReference AssetID="553014" Type="Non Print">
</AssetCrossReference>
<AssetCrossReference AssetID="553015" Type="Non Print">
</AssetCrossReference>
<AssetCrossReference AssetID="553016" Type="Non Print">
</AssetCrossReference>
<AssetCrossReference AssetID="553017" Type="Non Print">
</AssetCrossReference>
<AssetCrossReference AssetID="553018" Type="Non Print">
</AssetCrossReference>
<Values>
<Value AttributeID="5115">Section of main pool</Value>
<Value AttributeID="5137">114 apartments, four floors, no lifts</Value>
<Value AttributeID="5170">Property location</Value>
<Value AttributeID="5164">2 key</Value>
<Value AttributeID="5134">A comfortable property, the apartment is set on a pine-covered hillside - a scenic and peaceful location.</Value>
<Value AttributeID="5200">PROPERTY_ID</Value>
<Value AttributeID="5148">facilities include X,Y,Z</Value>
<Value AttributeID="5067">Self Catering. </Value>
<Value AttributeID="5221">Frequent organised daytime activities</Value>
</Values>
</Product>
</Product>
基本上我想在具有特定属性ID的xml文件中找到属性。所以它会像下面列出的代码一样,这是我对它应该是什么的解释。该代码不起作用,所以我会在某处出错。
这是相关行,我需要能够访问:
<Value AttributeID="5200">PROPERTY_ID</Value>
Dim productsXML As XElement = XElement.Load("C:\myFile.xml")
Dim foundNode As XElement
Dim query = From p In productsXML.Elements("Product").Descendants("Values") Where p.Attributes("attribute").ToString = "PROPERTY_ID"
foundNode = query.FirstOrDefault()
我能找到一个单独的节点使用下面的代码,但我需要找出一种方法来遍历属性值所以我可以将它们读入一个对象。 昏暗productsXML作为的XElement = XElement.Load(XMLFILE) 昏暗ParentNode作为的XElement 昏暗ChildNode作为的XElement 昏暗查询=从p在productsXML ... _ 凡p.Value = “PROPERTY_ID” ParentNode =查询。 FirstOrDefault() –
