[xml] How do I escape double quotes in attributes in an XML String in T-SQL?

Pretty simple question - I have an attribute that I would like to have double quotes in. How do I escape them? I've tried

• \"
• ""
• \\"

And I've made the @xml variable both xml type and varchar(max) for all of them.

 declare @xml xml --(or varchar(max) tried both)

 set @xml = '<transaction><item value="hi "mom" lol" 
    ItemId="106"  ItemType="2"  instanceId="215923801"  dataSetId="1" /></transaction>'

 declare @xh int
 exec sp_xml_preparedocument @xh OUTPUT, @xml

 insert into @commits --I declare the table, just removed it for brevity
 select
    x.*
 from openxml(@xh,'/transaction/item')
  WITH (
    dataItemId int,
     dataItemType int,
    instanceId int,
    dataSetId int,
    value varchar(max)
  ) x

Cannot comment anymore but voted it up and wanted to let folks know that " works very well for the xml config files when forming regex expressions for RegexTransformer in Solr like so: regex=".*img src="(.*)".*" using the escaped version instead of double-quotes.

tSql escapes a double quote with another double quote. So if you wanted it to be part of your sql string literal you would do this:

declare @xml xml 
set @xml = "<transaction><item value=""hi"" /></transaction>"

If you want to include a quote inside a value in the xml itself, you use an entity, which would look like this:

declare @xml xml
set @xml = "<transaction><item value=""hi &quot;mom&quot; lol"" /></transaction>"

In Jelly.core to test a literal string one would use:

<core:when test="${ name == 'ABC' }"> 

But if I have to check for string "Toy's R Us":

<core:when test="${ name == "Toy's R Us" }">

It would be like this, if the double quotes were allowed inside:

<core:when test="${ name == "Toy's R Us" }">
