Hi,
I've seen some postings on this but not exactly relating to this
posting. I'm reading in a large mail message as a string. In the
string is an xml attachment that I need to parse out and remove from
the message once processed. I have to do this as a string and not
using any CDO libraries. My problem is that there's normally a large
pdf in the file so when I read the file in it's massive and I don't
knwo if the XML is at the start/middle or end of the string. My regex
is as follows:
Regex rXMLPart = new Regex(
@"(?<Start>.*)(?<Middle>Content-Type:[^.*?]text\/xml.*?finaldistributeinformation.*?\<\/distributionList\>)(?<End>.*)",
RegexOptions.IgnoreCase |
RegexOptions.Singleline |
RegexOptions.IgnorePatternWhitespace);
and a sample of the string is:

I've cut the string short but that is the jist of it. If I were to run
against this attached string it all works fine but when really large
(with the rest of the pdf in) the match hangs:
Match mXMLPersonalisation = rXMLPart.Match(data);
Could anyone suggest a better way that I should do this. I need to get
the first part and the last part and join thus removing the XML part.
I also need to work on the XML to creat the new messages.
i.e.
string sStartPartOfEmailMessage =
mXMLPersonalisation.Groups["Start"].ToString();
string sXMLPartOfMessage =
mXMLPersonalisation.Groups["Middle"].ToString();;
string sEndPartOfEmailMessage =
mXMLPersonalisation.Groups["End"].ToString();;
SendXMLEmail(sStartPartOfEmailMessage, sXMLPartOfMessage,
sEndPartOfEmailMessage);
Any help would be much appreciated.
