Hi,
I need to add this string as an appsetting in the config file

^<(?<alarmNumber>\d{3})=(?<alarmStatus>[01])>$

This string has some characters that conflicts with the XML/config file
format....I don't remember the XML rules....

Any suggestion ?

Thanks & Regards,
Ashutosh

Hi Ashutosh,

^<(?<alarmNumber>\d{3})=(?<alarmStatus>[01])>$

> ^<(?<alarmNumber>\d{3})=(?<alarmStatus>[01])>$

Use the Settings of project's properties to generate this stuff.

Thanks for Alex's accurate answer to your question.

In the meanwhile, I would provide some additional information for you to
learn how to escape string embedded in xml file.
1. Using escaped characters.
The following table shows the invalid XML characters and their escaped
equivalents.
invalid XML Character : Replaced With
"<" : "<"
">" : ">"
"\"" : """
"\'" : "'"
"&" : "&"
In .NET Framework, we use " SecurityElement.Escape" method to do this job.
It is documented at
http://msdn.microsoft.com/en-us/library/system.security.securityel...
pe.aspx.

2. The other way is using CDATA Sections.
As documented as CDATA Sections [XML Standards]
(http://msdn.microsoft.com/en-us/library/ms2...)
"CDATA sections provide a way to tell the parser that there is no markup in
the characters contained by the CDATA section."
However, it has some restrictions for CDATA.
a. The sequence ]]> cannot appear within a CDATA section because this
sequence signals the end of the section.
b. CDATA can only be interpreted as element or entity markup, but not
attribute.

Please feel free to let me know if you have any question. It's our pleasure

Hi Hongye,
Thanks for the update...

I have read a lot about XML but it was around 1.5 years back so don't
remember anything....:)

Thanks again.
