I have an application that relies on JSON, and I realized yesterday
that I when the user types at least some of these characters (most
likely all, haven't had time to verify) that the parser has problems:
, { } [ ] " '
How can I escape these characters so that it is in the file, but can
still be parsed?
For example:
{data: ["I want a quote, 'and so here it is', [with something in
brackets]'", "and {more data}"]}
I also had a problem when a newline ('\n') was entered, so I turn those
into '<br>'.
Thanx for any help.

The JSON libraries should do all escaping for your, for instance for
JavaScript <http://www.json.org/js.html> there is the JSON.stringify
function which should do all escaping.
And if you want to create JSON with other programming languages then
there are libraries as well.
Note that brackets [] and {} inside of string literals do not need to be
escaped.

Thank you for the response.
I am not using the stringify function, so I will try using that on
Monday and see if the problem goes away.

Of the characters in the set
, { } [ ] " '
the only one requiring escapement is the ". This can be done by giving it a \
prefix. http://JSON.org/
Thank you. On Monday I will try these ideas.
I find JSON to be the best way for my Ajax application to transfer
data, but I am still getting used to it.

Just wondering... ...
Is there a class or method in the API that will automatically 'escape' all
the HTML special characters in a String, or a file? Something like the
'URLEncoder' class where the space character " " is converted into a plus
sign "+", for URL complience....
Example:
String myString = "<TD VALIGN=\"top\" CLASS=\"NavBarCell3\"><FONT
SIZE=\"-2\">";

Howdy,
Is there a way to explicitly escape special characters (particularly &
(&) and ' (')) when writing a data set with the WriteXml
method?
I know this is supposed to happen automatically (according to MS), but
in my case, it doesn't. I'm pulling data from MS-SQL with c#, filling
data tables with SqlDataAdapter and a query, adding tables to a
DataSet, then WriteXml to a file.

Hi,
I used XslCompiledTransform with the following Xsl file. The <xsl:text
disable-output-escaping="yes"does not work when using XslCompiledTransform
to do the trnasform (namely the output contain < not <), while it works when
using MSXML2 to do the transform. Does anyone have the same problem and how
to make the escape work? Thanks.

Yes, eval is a tool of the devil and I'll burn for using it. However,
in this instance it's quite handy and I'm quite lazy.
So, here's a weird one, and I'm wondering if anyone has a workaround.
I am pulling data off a server via AJAX, and some of that data has
non-English characters in it. The data is in the form of a json:
{"exitCode":1,"className":"clientRecords"
,"strAccountId":"100"
,"strName":"Dr. Gary A. Martin"

Hi everyone,
I'm having a bit of trouble understanding the purpose of escaping
nulls, and the use of addcslashes.
Firstly, the manual states that:
"Strictly speaking, MySQL requires only that backslash and the quote
character used to quote the string in the query be escaped. This
function quotes the other characters to make them easier to read in

We are dynamically changing the title property of nodes in our sitemappath to

optparse seems to be escaping control characters that I pass as
arguments on the command line. Is this a bug? Am I missing
something? Can this be prevented, or worked around?
This behaviour doesn't occur with non-control characters.
For example, if this program (called test.py):
from optparse import OptionParser
parser = OptionParser()
parser.add_option("-d", dest="delimiter", action="store")

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
