.Net Regex to parse Excel header / footer strings -

-

I am trying to create a .NET Regex which will separate the Excel header data string in its component parts. The following example shows the format of the raw data string I needed to parse: 

  & amp; LLeft-side text & amp; CCenter text and RRight-side text

Tags & amp; L, & amp; C & amp; R uses the left, center and right sections of header data respectively. Therefore, I need a regigax which will separate the above string into several sub-strings, each of which is & amp; L, & amp; C & amp; R will start with

Notes: Left, center, right square can be zero or more times in a header (where many opportunities for a given section will be added to the client code). The ampersand escape character is also used for formatting in each section, so reggax should use more than the above mentioned margin.

Thank you, in advance, for your suggestions.

((? & Lt; = & amp; nbsp;) (? [\ W \ W] +?) (? ((& Amp; c | Amp; R | $))))

This will match the text between A & L and C & L & R. (If & amp; c does not exist) or & amp; L and end (if & amp; si & amp; nbsp; does not exist), called in a designated match, LeftText gives you the A & For A & amp; By changing l and from the end section & amp; By removing c, and doing the same for the right section. It could be or maybe what you want, it is difficult to say this from a simple example given. The central part [\ w \ W] may need to be covered with loud because it can catch too much, but it works for example given.

SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
