我有一个从Excel导出的XML文件,该文件存储在SQL Server的表中的XML列中。 Excel文件有很多工作表,我只想存储一些工作表。有没有办法删除那些没有我要保留的名称的节点,类似于NOT IN
?
XML文件有这个标题:
<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:html="http://www.w3.org/TR/REC-html40">
这是XML的基本结构:
<Workbook>
<DocumentProperties>
</DocumentProperties>
<ExcelWorkbook>
</ExcelWorkbook>
<Styles>
<Style>
</Style>
</Styles>
<Worksheet ss:Name="Worksheet1">
<Table>
<Column.../>
<Column.../>
<Column.../>
<Row>
<Cell.../>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
<Cell.../>
</Row>
...
</Table>
</Worksheet>
并且节点重复几次。让我们说我只想保留&#34;工作表3&#34;,&#34;工作表4&#34;和&#34;工作表8&#34;。我怎么能这样做?我想我想在这种情况下使用update
和modify()
,类似于this question。唯一的区别是我想保留某些值,并删除其余值。
答案 0 :(得分:1)
试试这样:
DECLARE @xml XML=
'<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:html="http://www.w3.org/TR/REC-html40">
<DocumentProperties>
</DocumentProperties>
<ExcelWorkbook>
</ExcelWorkbook>
<Styles>
<Style>
</Style>
</Styles>
<Worksheet ss:Name="Worksheet1">
<Table>
<Column/>
<Column/>
<Column/>
<Row>
<Cell.../>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
</Row>
</Table>
</Worksheet>
<Worksheet ss:Name="Worksheet2">
<Table>
<Column/>
<Column/>
<Column/>
<Row>
<Cell.../>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
</Row>
</Table>
</Worksheet>
<Worksheet ss:Name="Worksheet3">
<Table>
<Column/>
<Column/>
<Column/>
<Row>
<Cell.../>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
<Cell><Data>...</Data></Cell>
</Row>
</Table>
</Worksheet>
</Workbook>';
SET @xml.modify('declare namespace dflt="urn:schemas-microsoft-com:office:spreadsheet";
declare namespace ss="urn:schemas-microsoft-com:office:spreadsheet";
delete /dflt:Workbook/dflt:Worksheet[@ss:Name="Worksheet2"]');
SELECT @xml;
您可以将多个过滤器表达式与&#34;或&#34; ...
组合在一起
