Cara terbaik untuk menghapus tag html dari string di server sql?

Saya punya data di SQL Server 2005 yang berisi tag html dan saya ingin menghapus semua itu, meninggalkan hanya teks di antara tag. Idealnya juga mengganti hal-hal seperti <dengan< , dll.

Apakah ada cara mudah untuk melakukan ini atau apakah seseorang sudah mendapatkan beberapa contoh kode t-sql?

Saya tidak memiliki kemampuan untuk menambahkan procs tersimpan yang diperpanjang dan sejenisnya, jadi saya lebih memilih pendekatan t-sql murni (lebih disukai yang kompatibel dengan sql 2000).

Saya hanya ingin mengambil data dengan html yang telah dilucuti, bukan memperbaruinya, jadi idealnya itu akan ditulis sebagai fungsi yang ditentukan pengguna, agar mudah digunakan kembali.

Jadi misalnya mengubah ini:

<B>Some useful text</B>&nbsp;
<A onclick="return openInfo(this)"
   href="http://there.com/3ce984e88d0531bac5349"
   target=globalhelp>
   <IMG title="Source Description" height=15 alt="Source Description" 
        src="/ri/new_info.gif" width=15 align=top border=0>
</A>&gt;&nbsp;<b>more text</b></TD></TR>

untuk ini:

Some useful text > more text

Ada UDF yang akan melakukan itu yang dijelaskan di sini:

Fungsi Buatan Pengguna untuk Menghapus HTML

CREATE FUNCTION [dbo].[udf_StripHTML] (@HTMLText VARCHAR(MAX))
RETURNS VARCHAR(MAX) AS
BEGIN
    DECLARE @Start INT
    DECLARE @End INT
    DECLARE @Length INT
    SET @Start = CHARINDEX('<',@HTMLText)
    SET @End = CHARINDEX('>',@HTMLText,CHARINDEX('<',@HTMLText))
    SET @Length = (@End - @Start) + 1
    WHILE @Start > 0 AND @End > 0 AND @Length > 0
    BEGIN
        SET @HTMLText = STUFF(@HTMLText,@Start,@Length,'')
        SET @Start = CHARINDEX('<',@HTMLText)
        SET @End = CHARINDEX('>',@HTMLText,CHARINDEX('<',@HTMLText))
        SET @Length = (@End - @Start) + 1
    END
    RETURN LTRIM(RTRIM(@HTMLText))
END
GO

Edit: catat ini untuk SQL Server 2005, tetapi jika Anda mengubah kata kunci MAX menjadi 4000, ini akan berfungsi di SQL Server 2000 juga.

Berasal dari jawaban @Goner Doug, dengan beberapa hal yang diperbarui:
- menggunakan REPLACE jika memungkinkan
- konversi entitas yang telah ditentukan sebelumnya seperti é(saya memilih yang saya butuhkan :-)
- beberapa konversi tag daftar<ul> and <li>

Jika HTML Anda terbentuk dengan baik, saya pikir ini adalah solusi yang lebih baik:

create function dbo.StripHTML( @text varchar(max) ) returns varchar(max) as
begin
    declare @textXML xml
    declare @result varchar(max)
    set @textXML = REPLACE( @text, '&', '' );
    with doc(contents) as
    (
        select chunks.chunk.query('.') from @textXML.nodes('/') as chunks(chunk)
    )
    select @result = contents.value('.', 'varchar(max)') from doc
    return @result
end
go

select dbo.StripHTML('This <i>is</i> an <b>html</b> test')

Ini bukan solusi baru yang lengkap tetapi koreksi untuk solusi afwebservant :

Coba ini. Ini adalah versi modifikasi dari yang diposting oleh RedFilter ... SQL ini menghapus semua tag kecuali BR, B, dan P dengan atribut yang menyertainya:

CREATE FUNCTION [dbo].[StripHtml] (@HTMLText VARCHAR(MAX))
RETURNS VARCHAR(MAX)
AS
BEGIN
 DECLARE @Start  INT
 DECLARE @End    INT
 DECLARE @Length INT
 DECLARE @TempStr varchar(255)

 SET @Start = CHARINDEX('<',@HTMLText)
 SET @End = CHARINDEX('>',@HTMLText,CHARINDEX('<',@HTMLText))
 SET @Length = (@End - @Start) + 1

 WHILE @Start > 0 AND @End > 0 AND @Length > 0
 BEGIN
   IF (UPPER(SUBSTRING(@HTMLText, @Start, 3)) <> '<BR') AND (UPPER(SUBSTRING(@HTMLText, @Start, 2)) <> '<P') AND (UPPER(SUBSTRING(@HTMLText, @Start, 2)) <> '<B') AND (UPPER(SUBSTRING(@HTMLText, @Start, 3)) <> '</B')
   BEGIN
      SET @HTMLText = STUFF(@HTMLText,@Start,@Length,'')
   END

   SET @Start = CHARINDEX('<',@HTMLText, @End)
   SET @End = CHARINDEX('>',@HTMLText,CHARINDEX('<',@HTMLText, @Start))
   SET @Length = (@End - @Start) - 1
 END

 RETURN RTRIM(LTRIM(@HTMLText))
END

Bagaimana jika menggunakan XQuery dengan satu liner:

DECLARE @MalformedXML xml, @StrippedText varchar(max)
SET @MalformedXML = @xml.query('for $x in //. return ($x)//text()')
SET @StrippedText = CAST(@MalformedXML as varchar(max))

Ini mengulang semua elemen dan mengembalikan teks () saja.

Untuk menghindari teks di antara elemen yang digabungkan tanpa spasi, gunakan:

DECLARE @MalformedXML xml, @StrippedText varchar(max)
SET @MalformedXML = @xml.query('for $x in //. return concat((($x)//text())[1]," ")')
SET @StrippedText = CAST(@MalformedXML as varchar(max))

Dan untuk menanggapi "Bagaimana Anda menggunakan ini untuk kolom:

  SELECT CAST(html_column.query('for $x in //. return concat((($x)//text()) as varchar(max))
  FROM table

Untuk kode di atas, pastikan Anda html_columnadalah tipe data xml, jika tidak, Anda perlu menyimpan html versi cast sebagaixml . Saya akan melakukan ini sebagai latihan terpisah ketika Anda memuat data HTML, karena SQL akan membuat kesalahan jika menemukan xml dalam format yang salah, misalnya tag awal / akhir tidak cocok, karakter tidak valid.

Ini sangat bagus saat Anda ingin membuat frasa pencarian, menghapus HTML, dll.

Perhatikan bahwa ini mengembalikan tipe xml, jadi CAST atau COVERT ke teks jika sesuai. Versi xml dari tipe data ini tidak berguna, karena ini bukan XML yang dibentuk dengan baik.

Ini adalah versi yang tidak memerlukan UDF dan berfungsi meskipun HTML berisi tag tanpa mencocokkan tag penutup.

TRY_CAST(REPLACE(REPLACE(REPLACE([HtmlCol], '>', '/> '), '</', '<'), '--/>', '-->') AS XML).value('.', 'NVARCHAR(MAX)')

Sementara jawaban Arvin Amir mendekati solusi satu baris penuh, Anda dapat mampir di mana saja; dia mendapat sedikit bug dalam pernyataan pilihnya (kehilangan akhir baris), dan saya ingin menangani referensi karakter yang paling umum.

Apa yang akhirnya saya lakukan adalah ini:

SELECT replace(replace(replace(CAST(CAST(replace([columnNameHere], '&', '&') as xml).query('for $x in //. return concat((($x)//text())[1]," ")') as varchar(max)), '&', '&'), ' ', ' '), ' ', ' ')
FROM [tableName]

Tanpa kode referensi karakter, dapat disederhanakan menjadi ini:

SELECT CAST(CAST([columnNameHere] as xml).query('for $x in //. return concat((($x)//text())[1]," ")') as varchar(max))
FROM [tableName]

Kode Patrick Honorez perlu sedikit perubahan.

Ini mengembalikan hasil yang tidak lengkap untuk html yang berisi <atau>

Ini karena kode di bawah bagian tersebut

- Hapus apa pun di antara tag

sebenarnya akan menggantikan <> menjadi tidak ada. Cara mengatasinya adalah dengan menerapkan dua baris di bawah ini di akhir:

set @HTMLText = replace(@htmlText, '&lt;' collate Latin1_General_CS_AS, '<'  collate Latin1_General_CS_AS)
set @HTMLText = replace(@htmlText, '&gt;' collate Latin1_General_CS_AS, '>'  collate Latin1_General_CS_AS)
