I have a batch file that I need to extract switches from.
The switches are in this format.
/Switch1=Value1 /Switch2="Value 2" /Switch3 /Switch4="C:\Program Files\DIR"
I need Switch=Value or Switch (only if it doesn't have any value for e.g. Switch3) extracted.
I am a beginner to regex. So far I have tried \/\w+=|\/\w+ this expression. But that doesn't give me a value.
Seems like you want this,
\/\w+(?:=(?:(["'])(?:(?!\1).)*\1|\S+))?
DEMO
Not much information, but here is something in perl to get you going:
perl -p -i -e 'print "$1=$3\n" if /\/(\w+)(=((\"[^"]*\")|\S+))?/;'
you use the lookback searching "switch." and look ahead for the first slash you will have to trim the values after but you got the values
(?<=Switch.=).+(?=/)
It can get hairy to parse a command line with switches.
Something like below.
# /([^ =]+)(?:=(?|"((?:[^"\\]*(?:\\.|[^"\\]*)*))"|([^ ]*)))?
/
( [^ =]+ ) # (1)
(?:
=
(?|
"
( # (2 start)
(?:
[^"\\]*
(?:
\\ .
|
[^"\\]*
)*
)
) # (2 end)
"
|
( [^ ]* ) # (2)
)
)?
Output

I have a regular expression to capture three fields in a HTML tag using boost::regex
"\\/\\/(.{1,3}?)\\.wikipedia\\.[a-z]+\\/wiki\\/(.*?)\\s*>(.*?)<"
So, from
Deutsch
I get
de
Porky%E2%80%99s" title="Porky’s – German" lang="de" hreflang="de"
Deutsch
But I´d like to have {de, Porky%E2%80%99s, Deutsch} instead.
How can I make my regex to stop matching the second field as soon as it finds the first white space?
I tried
"\\/\\/(.{1,3}?)\\.wikipedia\\.[a-z]+\\/wiki\\/(\\S*?)*>(.*?)<"
So the second field matches everything but whitespace but I get this crash report
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error> >'
what(): Ran out of stack space trying to match the regular expression.
This might work -
"//(.{1,3}?)\\.wikipedia\\.[a-z]+/wiki/([^\\s>\"]*).*?>(.*?)<"
I would use this instead -
"//(.{1,3}?)\\.wikipedia\\.[a-z]+/wiki/([^\\s>\"]*)[^>]*>(.*?)<"
Formatted:
//
( .{1,3}? ) # (1)
\.
wikipedia
\.
[a-z]+
/wiki/
( [^\s>"]* ) # (2)
[^>]*

( .*? ) # (3)

Here is the regular expression I was using that won't seem to match up. Can anyone identify why?
if ($allData =~ /(\d+)\s+(\d+|[N])\s+(\[\d+\])(.+)\s+(\[\d+\])(.+)\s+(\$\.+)\s+(\-|\+\d+\.\d+%|\-\d+\.\d+%)\s+(\d+)\s+(\-\d+|\-|\+\d+)\s+(\$\.+)\s+(\$\.+)\s+(\.+)\s+(\d+)/g)
{
$current[$i] = $1;
$last[$i] = $2;
$title[$i] = $4;
$week[$i] = $7;
$cume[$i] = $12;
printf("%-4s%-4s%-35s%-10s%-10s", $current[$i], $last[$i], $title[$i], $week[$i], $cume[$i]);
if ($last[$i] ne '-'){
$gain = $last[$i] - $current[$i];
}
if ($gain < $bigloss){
$bigloss = $gain;
$losstitle = $title[$i];
}
if ($gain > $biggain){
$biggain = $gain;
$gaintitle = $title[$i];
}
if ($last[$i] eq '-'){
if ($current[$i] < $bigdebut){
$bigdebut = $current[$i];
$bigdebuttitle = $title[$i];
}
if ($current[$i] > $weakdebut){
$weakdebut = $current[$i];
$weakdebuttitle = $title[$i];
}
}
$i++;
}
Could be the fix -
# /(\d+)\s+(\d+|[N])\s+(\[\d+\])(.+?)\s+(\[\d+\])(.+?)\s+(\$.+?)\s+(\-|\+\d+\.\d+%|\-\d+\.\d+%)\s+([\d,]+)\s+(\-\d+|\-|\+\d+)\s+(\$.+?)\s+(\$.+?)\s+(.+?)\s+(\d+)/g

Try this regex:
\d\s[A-Z0-9]\s\[\d\d\][A-Z][a-z]+(\s\b\w+\b){0,}\s(\(\d+\)\s)?\[\d\d\][A-Z]+[a-z]*\s(\(\w+\)\s)?\$(\d{1,3},){2}\d{3}\s-\s?\d+[,.]\d+((%\s\d,\d{1,3}\s-\s?\$?\d{1,3}(,\d{1,3}\s)?)|\s-\s\$\d{1,3},\d{1,3}\s)\s?\$\d{1,3},\d{1,3}(,\d{1,3})*\s\$\d{1,3}(,\d{1,3})*(\.\d+)?(\s\$\d+(\.)?\d+)?\s\d

How can I parse a maven filename into the artifact and and version?
The filenames look like this:
test-file-12.2.2-SNAPSHOT.jar
test-lookup-1.0.16.jar
I need to get
test-file
12.2.2-SNAPSHOT
test-lookup
1.0.16
So the artifactId is the text before the first instance of a dash and a number and the version is the text after the first instance of a number up to .jar.
I could probably do it with split and several loops and checks but it feels like there should be a simpler way.
EDIT:
Actually, the regex wasn't as complicated as I thought!
new File("test").eachFile() { file ->
String fileName = file.name[0..file.name.lastIndexOf('.') - 1]
//Split at the first instance of a dash and a number
def split = fileName.split("-[\\d]")
String artifactId = split[0]
String version = fileName.substring(artifactId.length() + 1, fileName.length())
println(artifactId)
println(version)
}
EDIT2: Hmm. It fails on examples such as this:
http://mvnrepository.com/artifact/org.xhtmlrenderer/core-renderer/R8
core-renderer-R8.jar
Basically its just this ^(.+?)-(\d.*?)\.jar$
used in multi-line mode if there is more than one line.
^
( .+? )
-
( \d .*? )

** Grp 0 - ( pos 0 , len 29 )

** Grp 1 - ( pos 0 , len 9 )

I have a string that contains a bunch of function calls within it. I need to extract every occurrence of the VariableSet function call. Functions can appear in any order. Here is an example:
parsedExpression = "VariableSet(b, 999)If(a = 0,"Black",SetColor(a,b,c))VariableSet("a" ,1.573) VariableSet( c,-2387)"
I need to find every match that starts with "VariableSet(" and ends with the first close parenthesis that follows it. So, for the example above, I need a list like this:
VariableSet(b, 999)
VariableSet("a" ,1.573)
VariableSet( c,-2387)
I planned to use the code below but I have not been able to determine the correct regex pattern. The best I could come up with is "VariableSet(.*(?i:)\b)" but it does not produce the list above.
Dim matches As MatchCollection = Regex.Matches(parsedExpression, "VariableSet\(.*(?i:\)\b)")
' Loop over matches.
For Each m As Match In matches
' Loop over captures.
For Each c As Capture In m.Captures
Dim varName As String = ""
Dim varValue As String = ""
Dim firstCommaPosition As Integer
'For every VariableSet that was found do the following:
'Parse the captured string to get the variable name and value
varName = c.Value.Replace("VariableSet(", "").Replace(")", "")
firstCommaPosition = varName.IndexOf(",")
varValue = varName.Substring(firstCommaPosition + 1)
varName = varName.Substring(0, firstCommaPosition).Replace("""", "")
'Set the variable
ce.Variables(varName) = ce.Evaluate(varValue)
'Remove this instance of VariableSet() function from parsedExpression
parsedExpression = parsedExpression.Replace(c.Value, "")
Next
Next
I would greatly appreciate it if someone could provide the correct regex pattern.
Maybe this will help you:
Dim strMatch As String = ""
Dim strVar1 As String = ""
Dim strVar2 As String = ""
Dim strExpression As String = "VariableSet(b, 999)If(a = 0,""Black"",SetColor(a,b,c))VariableSet(""a"" ,1.573) VariableSet( c,-2387)"
Dim rx As New RegularExpressions.Regex("VariableSet\((?<V1>.*?),(?<V2>.*?)\)", RegularExpressions.RegexOptions.IgnoreCase)
Dim rxMatch As RegularExpressions.MatchCollection = rx.Matches(strExpression)
For intI As Integer = 0 To rxMatch.Count - 1
strMatch = rxMatch(intI).Value 'VariableSet(b, 999)
strVar1 = rxMatch(intI).Groups("V1").ToString 'b
strVar2 = rxMatch(intI).Groups("V2").ToString ' 999
Next
VariableSet\([^)]*\) should be a direct replacement.
If you wanted to get fancy, all your code could be done using a single regex.
# VariableSet\((\s*"?\s*([^,")]*?)\s*"?\s*(?:,\s*"?\s*([^,")]*?)\s*"?\s*)?)\)
VariableSet
\( # Open paren
( # (1 start), Inside paren's
\s*
"? \s*
( [^,")]*? ) # (2), Var
\s*
"? \s*
(?:
, # Comma
\s*
"? \s*
( [^,")]*? ) # (3), Value
\s*
"? \s*
)?
) # (1 end)
\) # Close paren
Example input string:
VariableSet(b, 999)
VariableSet("a" ,1.573)
VariableSet( c,-2387)
VariableSet( , 999)
VariableSet( "aadsfasdf")
VariableSet( )
Output matches ( Var / Value ):
** Grp 2 - ( pos 12 , len 1 )
b
** Grp 3 - ( pos 16 , len 3 )
999
----------------
** Grp 2 - ( pos 35 , len 1 )

Expecting in the below way
comp_name= "hello", offset_min="24092014",offset_max="25092014"
In reality it is

What wrong did I do here??
Thanks in advance!!

You're missing a capture group 1.
Edit: Also note that groups 2 and 3 should be done like below, unless I'm reading you
wrong and you intend to retrieve the last part of particular number groups.
# '^/?company_data/([A-Za-z]+)/((?:(?:0?[1-9]|[12][0-9]|3[01])(?:0?[1-9]|1[012])(?:20)?[0-9]{2})*)/((?:(?:0?[1-9]|[12][0-9]|3[01])(?:0?[1-9]|1[012])(?:20)?[0-9]{2})*)$'
