I am sterilizing a JSON.Net object, and it contains many arrays. Here is the output I currently get:
"children": [
{
"children": [
{
},
{
}
}
However, just for the ease of reading and comparing, I would like to remove the line breaks between each brace and bracket and between the comma and next brace, so it looks like this:
"children": [ {
"children": [ {
}, {
}
}
I am already sterilizing my JSON with the Formatting.Indented argument, so I would like to know if there is another setting I can change so that JSON.Net sterilizes without the extra line brakes, but retaining the indented formatting.
There is no feature in Json.NET to give you that kind of indentation. You'll either have to do it yourself outside of Json.NET or modify the source code.
Can you split on '{' and then join the array again by spaces?

so I want to be able to extract and ID based on whether that object has a particular property. I NEED this to be done via Regex. Here is an example of the JSON I am working with:
{
"workspaceid": ws01,
"data": {
"workspacetitle": "My Workspace"
},
"collections": {
"projects": [{
"id": 01,
"data": {
"title": "My Project 01",
"enddateperiod": "2020-02-20T23:59:59",
"profilecomplete": true,
"synced": false
},
"lists": {
"projectcode": [{
"id": pcodered,
"data": {
"code": "myproject123",
"name": "OffshoreProject"
}
}]
}
}, {
"id": 02,
"data": {
"title": "My Project 02",
"enddateperiod": "2020-02-20T23:59:59",
"profilecomplete": false,
"synced": false
},
"lists": {
"projectcode": [{
"id": pcodered,
"data": {
"code": "myproject123",
"name": "OffshoreProject"
}
}]
}
}]
}}
So what I want to extract is the ID of the project whose profile is not complete ("profilecomplete":false). So in this case, I want to select Project 2's id (which is 02).
How can I do this via Regex? I've managed to remove all of the whitespace and new lines as well so the JSON is essentially all one long line. Would it be easier to extract the Regex like this? Either way, I could use some help on how to get this ID.
NOTE: The format of the JSON cannot change.
This one works
/"id": ([^,]*?)(?=,[^{]*{[^}]*"profilecomplete": false)/
Explanations :
Read all these chars first "id":[space]
Then read in a group chars that aren't ","
And then a lookahead : you expect "," then chars that aren't "{", then "{"; and finally, before matching the closing "}", you want to read "profilecomplete": false
But I agree that a JSON parser would have been my preferred option!
Using Jtoken.FromObject results in double curly brackets which results in a JSON parse error, here is a simple example
object jtokenObject = new { Data = JToken.FromObject(new {Name="some name"}) };
Console.WriteLine(jtokenObject);
//{ Data = {{ "Name": "some name"}} }
JToken anotherToken = JToken.FromObject(jtokenObject);
Console.WriteLine(anotherToken);
//{{ "Data": { "Name": "some name" }}}
Does anyone know about a quick fix that does not require converting to string and removing or serializing / deserializing?
I'm working on a regular expression and I just can't figure out what the problem is. I've tried several helping sites like http://derekslager.com/blog/posts/2007/09/a-better-dotnet-regular-expression-tester.ashx and http://gskinner.com/RegExr/ but somehow when I put the tested regular expression in c# it is not processed correctly

I need to convert this JSON to a XML of course this is not directly possible because of the "16x16", "24x24", "32x32" and "48x48" bits inside the json which would be transformed into <16x16 />, <24x24 />, <32x32 /> and <48x48 /> tags which are invalid tags.
The receiver of the XML doesn't even need those avatar urls so I was thinking about stripping out the entire "avatarUrls":"{ ..... }, bit before handing the json over to JSON.NET for converting.
I was thinking about doing this using a regular expression. After some testing on the mentioned websites I came to the following regular expression:
("avatarUrls)(.*?)("displayName")
The Regex.Replace method should remove all found results instead of the third groep (a.k.a. "displayName")
The website http://derekslager.com/blog/posts/2007/09/a-better-dotnet-regular-expression-tester.ashx shows me the correct groups and find results and says that the mentioned regular expression should be used inside C# is:
#"(""avatarUrls)(.*?)(""displayName"")"
So inside C# I wrote the following:
string expression = #"(""avatarUrls)(.*?)(""displayName"")";
string result = Regex.Replace(json, expression, "$3");
return result;
When I look at the result after the RegexReplace nothing has been replaced. Does anyone see what I did wrong here?
I wouldn't use regular expressions to remove these nodes. I'd instead use JSON .Net to remove the nodes you don't want.
I refer to the quote:
Some people, when confronted with a problem, think “I know, I'll use
regular expressions.” Now they have two problems.
Using the answer found here, you could write:
var jsonObject = (JObject)JsonConvert.DeserializeObject(yourJsonString);
removeFields(jsonObject.Root, new[]{"avatarUrls"});
(Note that I was not sure if you wanted to delete both "avatarUrls" nodes.)
There's an overload of Regex.Replace that takes RegexOptions that you may need to look into. For example, for . to matches every character (instead of every character except \n), you'd need to specify RegexOptions.Singleline. Also, it looks like you're trying to replace every match of #"(""avatarUrls)(.*?)(""displayName"")" with $3 is that intended? You might be better off doing something like this:
var match = Regex.Match(json, pattern, options);
while (match.Success) {
// Do stuff with match.Groups(1)
match = match.NextMatch();
}
However... I'm not really sure that's going to replace it in the source string.
The problem is something completely different:
Inside the following string:
{"16x16":"http://www.gravatar.com/avatar/88994b13ab4916972ff1861f9cccd4ed?d=mm&s=16, "32.32"
There is an '&' the magic symbol that indicates a next parameter is started. Therefor no complete JSON is read and therefor it cannot convert it properly. It also indicates why nothing is being replaced inside the regular expression I used because "displayName" is not inside the string, so nothing matches.
I have been using Json.NET to serialize my objects in memory to json. When I call the following lines of code:
string json = JsonConvert.SerializeObject(template, Formatting.Indented);
System.IO.File.WriteAllText(file, json);
I get the following in a text file:
{
"template": {
"title": "_platform",
"description": "Platform",
"queries": [
{
"query": "// *******************************\n// -- Remove from DurationWindow at the end \n// *******************************\t\n"
}
],
"metadata": ""
}
}
a query is an object I pulled out of the database, that has a string value. When I use xml and write to file (Using XDocument), the new lines in the string (as well as the \t) are properly resolved into tabs and new lines in the file. Is it possible to get the same effect here with json.Net ?
The line-break and tab chars are not valid in JSON values, and JSON.net won't render \t and \n into tab & line break characters actually. To display this nicely, you could do:
var withLineBreaks = json.Replace("\\n", "\n").Replace("\\t", "\t");
However if you do that, the text that you're writing will be invalid JSON, and you'll have to strip out tab and line breaks when you read it back if you want to deserialize it.
I'm using Json.NET in a .NET 4.0 application in order to convert a JSON RESTful response into XML. I am running into issues converting JSON into XML if a JSON child key has a space.
So far, I am able to convert most JSON responses.
Here are example responses along with the code which I am using to generate the XML.
{
num_reviews: "2",
page_id: "17816",
merchant_id: 7165
}
And here is the response which is causing an error:

So far, I have been considering on creating a mapping of the JSON data to a C# object and generating XML for that class. However, is there a way to keep this dynamic? Or is there a way to treat spaces as %20 encodings?
This question is same as how to validate JSON string before converting to XML in C#
If you have any further queries, please let me know.
You can call XmlConvert.EncodeName, which will escape any invalid characters using _s.
For example, a space would become _x0020_.
You cannot have an XMLElement Name with a space in it. You would need to replace the space with an Underscore or anyother element. If that is not feasible for you, try putting that value as an attribute for that Node.
I hope this makes sense.
