## Usage Information

The Extract Text processor provides different results based on whether named capture groups are enabled.

## Example

Here is a like for like example that illustrates this.

#### Data

`
            foo\r\nbar1\r\nbar2\r\nbar3\r\nhello\r\nworld\r\n
`

### Without named capture groups

#### Configuration

Property Name | Property Value
regex.result1 | (?s)(.*)
regex.result2 | (?s).*(bar1).*
regex.result3 | (?s).*?(bar\\d).*
regex.result4 | (?s).*?(?:bar\\d).*?(bar\\d).*?(bar3).*
regex.result5 | (?s).*(bar\\d).*
regex.result6 | (?s)^(.*)$
regex.result7 | (?s)(XXX)

#### Results

Attribute Name | Attribute Value
regex.result1 | `
    foo\r\nbar1\r\nbar2\r\nbar3\r\nhello\r\nworld\r\n
`
regex.result2 | bar1
regex.result3 | bar1
regex.result4 | bar2
regex.result4.0 | `
    foo\r\nbar1\r\nbar2\r\nbar3\r\nhello\r\nworld\r\n
`
regex.result4.1 | bar2
regex.result4.2 | bar3
regex.result5 | bar3
regex.result6 | `
    foo\r\nbar1\r\nbar2\r\nbar3\r\nhello\r\nworld\r\n
`
regex.result7 |

### With named capture groups

#### Configuration

Property Name | Property Value
Enable named group support | True
regex.result1 | (?s)(?<ALL>.*
regex.result2 | (?s).*(?<BAR1>bar1).*
regex.result3 | (?s).*?(?<BAR1>bar\d).*
regex.result4 | (?s).*?(?:bar\d).*?(?<BAR2>bar\d).*?(?<BAR3>bar3).*
regex.result5 | (?s).*(?<BAR3>bar\d).*
regex.result6 | (?s)^(?<ALL>.*)$
regex.result7 | (?s)(?<MISS>XXX)

#### Results

Attribute Name | Attribute Value
regex.result1 | `
    foo\r\nbar1\r\nbar2\r\nbar3\r\nhello\r\nworld\r\n
`
regex.result2.BAR1 | bar1
regex.result3.BAR1 | bar1
regex.result4.BAR2 | bar2
regex.result4.BAR2 | bar2
regex.result4.BAR3 | bar3
regex.result5.BAR3 | bar3
regex.result6.ALL | `
    foo\r\nbar1\r\nbar2\r\nbar3\r\nhello\r\nworld\r\n
