如何通過從SQL表獲取數據來製作帶有custome標記xml文件的DGML圖

Question

我想通過從SQL表中獲取數據來構建帶有自定義標記的DGML。

表：

UCId UCPre       UCPost       UCNext 
----------------------------------------------------------------------------------------------- 
UC01 User must be Registerd   User is Loggined sucessfully UC02  
UC02 User is Loggined sucessfully User is added     UC03  
UC03 File must be selected   File is added     NULL  
UC04 File is added     File is deleted     NULL 
UC05 User is Loggined sucessfully User is deleted     NULL  

我想在節點下面的標籤我想從UCID柱和UCNext列讀取UCID

<?xml version="1.0" encoding="utf-8"?> 
<DirectedGraph Title="TestT" xmlns="http://schemas.microsoft.com/vs/2009/dgml"> 
    <Nodes> 
    <Node Id="UC01" Label="UC01" /> 
    <Node Id="UC02" Label="UC02" /> 
    <Node Id="UC03" Label="UC03" /> 
    </Nodes> 

我想要的節點之間的鏈接的XML在作爲TABEL以上UC01數據的基礎上，下一狀態是UCO 2。如何我可以設置此通過編碼使得正確鏈路節點之間創建

<Links> 
    <Link Source="UC01" Target="UC02" Label="1"/> 
    <Link Source="UC02" Target="UC03" Label="2" /> 
    </Links> 
    <Properties> 
    <Property Id="Background" Label="Background" Description="The background color" DataType="System.Windows.Media.Brush" /> 
    <Property Id="Bounds" DataType="System.Windows.Rect" /> 
    <Property Id="Label" Label="Label" Description="Displayable label of an Annotatable object" DataType="System.String" /> 
    <Property Id="LabelBounds" DataType="System.Windows.Rect" /> 
    <Property Id="Stroke" DataType="System.Windows.Media.Brush" /> 
    <Property Id="Title" DataType="System.String" /> 
    <Property Id="UseManualLocation" DataType="System.Boolean" /> 
    </Properties> 
</DirectedGraph> 

如何通過c＃或java來實現這一點請幫忙？通過所有記錄循環創建節點：

Answer 1

請參閱此代碼示例：https://gist.github.com/azukipochette/4644291

第1步。

步驟2：再次遍歷所有記錄以創建鏈接（找到由標籤在步驟1中創建的節點對）。
