ASKER
Sorry, I should have asked you describe with string.format()
ASKER
The problem, I need to read XML from a file and write to a second file with changes. I had a real problem with this... I tried... \' and '' (double single quote) and the 2008 compiler complained.
Please show what does the sample xml looks like and what you want the change to be and we can go from there.

which .net version u using?
Please explain your question and also if it is possible give sample code ..
>>I need to read XML from a file and write to a second file with changes.
what changes?
after reading the xml, what manipulations you wish to do before writing to the 2nd file?

'ABC' as a string ====> '\ABC\'
So you are reading an xml something like this:
<Test>'ABC'</Test>
and you want to write this to some other place as \'ABC\'. Is my understanding correct and also what is the 2nd file type - a text file, database or another xml?

this is what need to read, manipulate, then write to a new file. This xml is sourced to a .resx file.

Microsoft ResX Schema
Version 2.0
The primary goals of this format is to allow a simple XML format
that is mostly human readable. The generation and parsing of the
various data types are done through the TypeConverter classes
associated with the data types.
Example:
... ado.net/XML headers & schema ...
<resheader name="resmimetype">text/mi crosoft-re sx</reshea der>
<resheader name="version">2.0</reshea der>
<resheader name="reader">System.Resou rces.ResXR esourceRea der, System.Windows.Forms, ...</resheader>
<resheader name="writer">System.Resou rces.ResXR esourceWri ter, System.Windows.Forms, ...</resheader>
<data name="Name1"><value>this is my long string</value><comment>thi s is a comment</comment></data>
<data name="Color1" type="System.Drawing.Color , System.Drawing">Blue</data >
<data name="Bitmap1" mimetype="application/x-mi crosoft.ne t.object.b inary.base 64">
<value>[base64 mime encoded serialized .NET Framework object]</value>
</data>
<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-mi crosoft.ne t.object.b ytearray.b ase64">
<value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
<comment>This is a comment</comment>
</data>
There are any number of "resheader" rows that contain simple
name/value pairs.
Each data row contains a name, and value. The row also contains a
type or mimetype. Type corresponds to a .NET class that support
text/value conversion through the TypeConverter architecture.
Classes that don't support this are serialized and stored with the
mimetype set.
The mimetype is used for serialized objects, and tells the
ResXResourceReader how to depersist the object. This is currently not
extensible. For a given mimetype the value must be set accordingly:
Note - application/x-microsoft.ne t.object.b inary.base 64 is the format
that the ResXResourceWriter will generate, however the reader can
read any of the formats listed below.
mimetype: application/x-microsoft.ne t.object.b inary.base 64
value : The object must be serialized with
: System.Runtime.Serializati on.Formatt ers.Binary .BinaryFor matter
: and then encoded with base64 encoding.
mimetype: application/x-microsoft.ne t.object.s oap.base64
value : The object must be serialized with
: System.Runtime.Serializati on.Formatt ers.Soap.S oapFormatt er
: and then encoded with base64 encoding.
mimetype: application/x-microsoft.ne t.object.b ytearray.b ase64
value : The object must be serialized into a byte array
: using a System.ComponentModel.Type Converter
: and then encoded with base64 encoding.

A followup question, perhaps it might be best to work with the xml as a document structure (when manipulating) rather than text? The strategy that I considered was to read the file and add the notes to the schema and write it out again.
Perhaps I should be reading the "template" xml schema, and add the data as an xml node and write it again. If this is the recommended approach, I am not clear on how to do this.

I may have mistakenly misrepresented the problem. The problem, how to handle double quotes as in the above RESX file example.
Thanks!
Tim
Thanks!

The string.Format statement reports compiler errors. Spending too much time on XMLwriters... and will just write out the XML using a stringbuilder class and validate the XML using XMLDocument. Why would the string.Format throw compiler errors?
System.Text.Stringbuilder sb = new StringBuilder();
sb.AppendLine(string.Forma
;
ASKER
A solution which I found on other sources. This method seemed to correct all compiler errors. Thanks all for suggestions.
Stringbuilder LocalResourceXML = new StringBuilder();
LocalResourceXML.AppendLin e(@" <?xml version=""1.0"" encoding=""utf-8"" ?>");
Stringbuilder LocalResourceXML = new StringBuilder();
LocalResourceXML.AppendLin

Many many thanks. This is exactly what I needed. I implemente the prototype: string xx = string.format(@"zigglywigg ets are "'{0}"" ", annoying") which worked. Your solutions describe options which are seemingly easier to implement in code.
Many thanks. The points are yours!
