将 HTML 符号小数解码为 Power BI 中的实际符号

Question

数据在文本中有 HTML 个值：

col1
-------------------------------------------------------------
Drell-Yan Process Background Estimation Using e&#956; Method
Expressions of constant &#960;
Computational Analysis of Protein &#946;-Structure
&#948;13C and 14C Measurements in Aerosol Particles

我需要获取实际符号而不是所有 HTML 十进制值。

Answer 1

powerquery-m中的

Html.Table可以将HTML十进制值解码为可见符号：

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("PY7BCsIwDIZfJcyrg03nUHaa06MwEA8ydyg1arFrR5KCvr1l4C7JId/3/+m65EBobXpVDlryGplhr/T7ST64OxxZzKDEeAcXNu4JeAtZtioXu01ZwQnl5e9Jv+yS42ek6EaQwT9Axy3KCfzxMqsmrvHDGGRKVBbqOL5sJiW2Cxo3G0VZpWehoCUQTu582Vb5ugFDkBdNfEJxJAZ0whD9Gsmzt9AqEqMtctL3Pw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [col1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"col1", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "HtmlTable", each Html.Table([col1],{{"HtmlDecoded",":root"}})),
    #"Expanded HtmlTable" = Table.ExpandTableColumn(#"Added Custom", "HtmlTable", {"HtmlDecoded"}, {"HtmlDecoded"})
in
    #"Expanded HtmlTable"

或到位：

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("PY7BCsIwDIZfJcyrg03nUHaa06MwEA8ydyg1arFrR5KCvr1l4C7JId/3/+m65EBobXpVDlryGplhr/T7ST64OxxZzKDEeAcXNu4JeAtZtioXu01ZwQnl5e9Jv+yS42ek6EaQwT9Axy3KCfzxMqsmrvHDGGRKVBbqOL5sJiW2Cxo3G0VZpWehoCUQTu582Vb5ugFDkBdNfEJxJAZ0whD9Gsmzt9AqEqMtctL3Pw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [col1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"col1", type text}}),
    Decoded = Table.TransformColumns(#"Changed Type", {{"col1", each Table.FirstValue(Html.Table(_,{{"HtmlDecoded",":root"}})) }} )
in
    Decoded
