Question

I am working something at the moment and need to extract an attribute from a big list tags, they are formatted like this:

<appid="928" appname="extractapp" supportemail="[e-mail]" /><appid="928" appname="extractapp" supportemail="[e-mail]" />

The tags are repeated one after another and all have different appid, appname, supportemail.

I need to just extract all of the support emails, just the email address, without the supportemail=

Will I need to use two regex statements, one to seperate each individual tag, then loop through the result and pull out the emails?

I would then go through and Add the emails to a list, then loop through the list and write each one to a txt file, with a comma after it.

I’ve never really used Regex too much, so don’t know if it’s suitable for the above?

I would spend more time trying it myself but it’s quite urgent. So hopefully somebody can help.

Answer 1

Using XML is better, perhaps, but here’s the regular expression you’d use (in case there’s a particular reason you need/want to use regular expressions to read XML):

(appid="(?<AppID>[^"]+)" appname="(?<AppName>[^"]+)" supportemail="(?<SupportEmail>[^"]+)")

You can just take the last bit there for the support email but this will extract all of the attributes you mentioned and they will be “grouped” within each tag.
