Re: [xsl] How to unescape slash character using xml-to-json ?

["Matthieu RICAUD-DUSSARGET m.ricaud-dussarget@xxxxxxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi Tim, Hi Michael,

Thanks for your answers, links and explanations.

I applied Martinbs solution as suggested:

xml-to-json(.) => parse-json() => serialize(map {'method': 'json',
'use-character-maps' : map {'/' : '/'}})

Parsing the json to serialize it back with character-maps looks quite
bcomplexb for such a serialization option.
I understand the debate on this subject. Maybe having an option to let the
user choosing could have been a good compromiss ?
Anyway this method works well b:
Except it applies to the whole json : I canbt say this key value has to be
solidus escaped and this one not (I could maybe work within the map for this)

Therebs also an unexpected side effect : the output json is not in the same
order.
I also loose the indent option (which I had to move to the serialize method)

For example, for this input :
<fn:map xmlns:fn="http://www.w3.org/2005/xpath-functions";>
   <fn:string key="format">text/xml</fn:string>
   <fn:string key="contentType">text</fn:string>
   <fn:string key="rights">public</fn:string>
   <fn:string key="source">flash</fn:string>
   <fn:array key="altKeys">
      <fn:string>flash:id:d28073e1005</fn:string>
   </fn:array>
</fn:map>>

When using: xslLib:xjson2json(*, map{'indent':true()})
I get this json output:


  { "format" : "text\/xml",
    "contentType" : "text",
    "rights" : "public",
    "source" : "flash",
    "altKeys" :
    [ "flash:id:d28073e1005" ] }

And when using:
xslLib:xjson2json(*) => parse-json() => serialize(map {'method': 'json',
'indent':true(), 'use-character-maps' : map {'/' : '/'}})
I get this json output:
{
  "contentType":"text",
  "rights":"public",
  "format":"text/xml",
  "source":"flash",
  "altKeys": [
    "flash:id:d28073e1005"
   ]
 }

Which is not a probem as json properties order doesn't matter, just wondering
why actually ?

Cheers

ObjetB : Re: [xsl] How to unescape slash character using xml-to-json ?

Note: the reason that solidus is escaped by default is because the JSON can
then be embedded in an HTML5 script tag. See explanation here:

ped

There was considerable debate about this decision, as you can imagine: it's
one that suits some use cases and not others.

Hi all,
B 
I need to generate this json output :
B 
{"test":"foo/bar"}
B 
I use XSLT3 function fn:xml-to-json to do this.
My input is :
B 
<fn:map xmlns:fn="http://www.w3.org/2005/xpath-functions";>
B B B  <fn:string key="test" escaped="false">foo/bar</fn:string>
</fn:map>
B 
But I always get this result with escaped slash :
B 
{"test":"foo\/bar"}
B 
Reading the spec at https://www.w3.org/TR/xslt-30/#func-xml-to-json at
paragraph bStrings are escaped as follows:b it looks like I canbt
unescape b/b (solidus?) character.
B 
Is there really no way to do that using XSLT3 B json functionality ? Did I
missed something obvious ?
B 
Here is a running test : https://xsltfiddle.liberty-development.net/bwdwrV
B 
Thanks in advance,
B
