关于读取XML
XML格式如下:   
   <?xml   version= "1.0 "   standalone= "yes "?>  
  <DocumentElement>  
        <Sheet>  
              <Catalog> 01 </Catalog>  
              <TableName> 01-ASIC </TableName>  
              <SearchField> Part   Type </SearchField>  
              <SearchField> IC   Package </SearchField>  
              <SearchField> PCB   Footprint </SearchField>  
              <Specification> PCB   Footprint </Specification>  
              <Specification> Maker </Specification>  
              <Specification> Maker   Part   Number </Specification>  
  </Sheet>  
        <Sheet>  
              <Catalog> 02 </Catalog>  
              <TableName> 02-Memory   IC </TableName>  
              <SearchField> Part   Type </SearchField>  
              <SearchField> Address   Access   Time   (Unit   :   ns) </SearchField>  
              <SearchField> Package </SearchField>  
              <SearchField> PCB   Footprint </SearchField>  
              <Specification> PCB   Footprint </Specification>  
              <Specification> Maker </Specification>  
              <Specification> Maker   Part   Number </Specification>  
        </Sheet>  
        <Sheet>  
              <Catalog> 06 </Catalog>  
              <TableName> 06-Virtual   Capacitance </TableName>  
              <Specification> Value </Specification>  
              <Specification> Temperature   Characteristics </Specification>  
        </Sheet>  
  </DocumentElement>  
 采用ReadXml()读取,数据存放到Dataset中便是三个表,格式分别如下: 
 表一: 
 Catalog TableName   
 01    01-ASIC 
 02    02-Memory   IC 
 06    06-Virtual   Capacitance   
 表二: 
 SearchField_text   
 Part   Type 
 IC   Package 
 PCB   Footprint 
 Part   Type 
 Address   Access   Time   (Unit   :   ns) 
 Package 
 PCB   Footprint   
 表三: 
 Specification_text   
 PCB   Footprint 
 Maker 
 Maker   Part   Number 
 PCB   Footprint 
 Maker 
 Maker   Part   Number 
 Value 
 Temperature   Characteristics   
 现在问题是:怎么在这三个表之间建立关系呢?关系如下,当我读取“表一”的“01”时,那么“表二”的“Part   Type”,“IC   Package”,“PCB   Footprint”以及“表三”的“PCB   Footprint”,“Maker”,“Maker   Part   Number”的内容也能够同时获取。
