返回（pd.数据帧（数据））

在这种情况下，如果单元格索引为空或null，如何处理？（在这种情况下，单元格索引7并不总是存在）。Win32库无法帮助我在这种情况下，我尝试过，但它没有处理数千个文件所需的性能

尝试使用“索引”属性而不是单元格元素索引：

# add "ss" namespace declaration to the namespaces map
ns = {"doc": "urn:schemas-microsoft-com:office:spreadsheet", "ss": "urn:schemas-microsoft-com:office:spreadsheet"}

# in function call reference element "Cell" having an attribute "Index" with value "7"
getvalueofnode(node.find('doc:Cell[@ss:Index="7"]/doc:Data', ns))

同样的方法也可以用于其他细胞

此代码将尝试查找具有给定索引属性的单元格元素。如果未找到，函数getvalueofnode（）将返回None

# add "ss" namespace declaration to the namespaces map
ns = {"doc": "urn:schemas-microsoft-com:office:spreadsheet", "ss": "urn:schemas-microsoft-com:office:spreadsheet"}

# in function call reference element "Cell" having an attribute "Index" with value "7"
getvalueofnode(node.find('doc:Cell[@ss:Index="7"]/doc:Data', ns))
