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。
静候佳音......
