Импорт файла XML, связывающего количество родительских узлов с их атрибутами

Question

У меня есть следующий код для импорта XML-файла и преобразования в табличную форму в Excel 2016 qith Power Query.

let
    Source = Xml.Tables(File.Contents("D:\XML\file.xml")),
    Table0 = Source{0}[Table],
    #"Changed Type" = Table.TransformColumnTypes(Table0,{{"Attribute:index", Int64.Type}}),
    #"Expanded row" = Table.ExpandTableColumn(#"Changed Type", "row", {"column"}, {"row.column"}),
    #"Expanded row.column" = Table.ExpandTableColumn(#"Expanded row", "row.column", {"text"}, {"row.column.text"}),
    #"Expanded row.column.text" = Table.ExpandTableColumn(#"Expanded row.column", "row.column.text", {"Element:Text", "Attribute:fontName", "Attribute:fontSize", "Attribute:x", "Attribute:y", "Attribute:width", "Attribute:height"}, {"row.column.text.Element:Text", "row.column.text.Attribute:fontName", "row.column.text.Attribute:fontSize", "row.column.text.Attribute:x", "row.column.text.Attribute:y", "row.column.text.Attribute:width", "row.column.text.Attribute:height"})
in
    #"Expanded row.column.text"

Я получаю почти нужный вывод (индекс и остальные столбцы атрибутов), но я не знаю, как добавить столбец для страницы, строки и столбца, соответствующих каждому атрибуту.

Может кто-нибудь помочь мне с этим, пожалуйста.

Это вывод, который я получаю с моим кодом.

Так как эти номера строк и столбцов не являются частью XML, вам придется вычислять их самостоятельно, пока вы углубляетесь в уровни.

let
    Source = Xml.Tables(File.Contents("<Path to XML file>")),
    #"Expanded Table" = Table.ExpandTableColumn(Source, "Table", {"Attribute:index", "row"}, {"index", "row"}),
    #"Changed Type" = Table.TransformColumnTypes(#"Expanded Table",{{"index", Int64.Type}}),
    #"Expanded row" = Table.ExpandTableColumn(#"Changed Type", "row", {"column"}, {"column"}),
    #"Added Index" = Table.AddIndexColumn(#"Expanded row", "row_index", 0, 1),
    #"Added Custom" = Table.AddColumn(#"Added Index", "row", (C) => if C[column] = null then null else Table.RowCount(Table.SelectRows(#"Added Index", each [index] = C[index] and [row_index] <= C[row_index]))-1, Int64.Type),
    #"Expanded column" = Table.ExpandTableColumn(#"Added Custom", "column", {"text"}, {"text"}),
    #"Expanded text" = Table.ExpandTableColumn(#"Expanded column", "text", {"Element:Text", "Attribute:fontName", "Attribute:fontSize", "Attribute:x", "Attribute:y", "Attribute:width", "Attribute:height", "Attribute:fontStyle"}, {"Text", "fontName", "fontSize", "x", "y", "width", "height", "fontStyle"}),
    #"Added Index1" = Table.AddIndexColumn(#"Expanded text", "col_index", 0, 1),
    #"Added Custom1" = Table.AddColumn(#"Added Index1", "column", (C) => if C[row] = null then null else Table.RowCount(Table.SelectRows(#"Added Index1", each [index] = C[index] and [row] = C[row] and [col_index] <= C[col_index]))-1, Int64.Type),
    #"Removed Other Columns" = Table.SelectColumns(#"Added Custom1",{"index", "Text", "fontName", "fontSize", "x", "y", "width", "height", "row", "column", "fontStyle"}),
    #"Reordered Columns" = Table.ReorderColumns(#"Removed Other Columns",{"index", "row", "column", "Text", "fontName", "fontSize", "fontStyle", "x", "y", "width", "height"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Reordered Columns",{{"fontName", type text}, {"fontSize", type number}, {"x", type number}, {"y", type number}, {"width", type number}, {"height", type number}, {"Text", type text}, {"fontStyle", type text}})
