"grep" in C#

Hi All,

I am trying to make two changes to the block of C# code at the bottom of this page. Any help would be greatly appreciated!

1) the input files are not currently valid XML files, so I used to run the following script first. Is there anyway to replicate the exact functionality of this script in the C# code (such that as the C# app opens each file, it first performs this modification)?

Code:

while read THISFILE
do
    echo '<uspto>' > /tmp/patentconversion.xml
    cat $THISFILE \
        | grep -v '<?xml' \
        | grep -v '<!DOCTYPE' \
        | grep -v '<!ENTITY' \
	| grep -v ']>' \
        | tr '\n#&\t' ' ' \
        >> /tmp/patentconversion.xml
    echo '</uspto>' >> /tmp/patentconversion.xml
done

2) Instead of creating a separate output file for each file, how can I modify the C# code such that each additional output is appended to the first output file (i.e. all files get outputted to the same c:\code-gen\output\" + file.Name file)?

Code:

// create directory object

System.IO.DirectoryInfo dirCustom = new System.IO.DirectoryInfo(@"c:\code-gen\employees");

//use GetFiles method to get all the files in the directory

System.IO.FileInfo[] filCustom = dirCustom.GetFiles();

//create the "output" directory

System.IO.Directory.CreateDirectory(@"C:\code-gen\output");

//iterate through each file in turn, create a source and target object for each file, then pass this to the Run method

foreach (System.IO.FileInfo file in filCustom)

{
Altova.IO.Input source2Source = new Altova.IO.FileInput(@"C:\code-gen\employees" + file.Name);

Altova.IO.Output target2Target = new Altova.IO.FileOutput(@"c:\code-gen\output\" + file.Name);

MappingMapTotargetObject.Run(
source2Source,
target2Target);
}
