Split (extract section)

{{ split | start: "" | end: "" | removeHeaders: "true" }}
Parameters:
-
Start: Match string to begin the split. Included in the result. Case-sensitive.
-
End: The match string to end the split. Excluded from the result. Case-sensitive.
-
Remove Headers: If true, remove repeating lines of text (e.g. headers or footers). If false, do not remove repeating text.
Returns: The resulting split chunk of text.
Example:
I have 20 cats and 40 dogs.
{{ split | start: "20" | end: "40" | removeHeaders: false }}

20 cats and
Split (on delimiter)
Split a string on the specified delimiter, and store it in the variable name you choose for later use (eg, take a list of comma-separated names, and run a loop with each value).
{{ splitDelim | delimiter: "," | outputJson: "" | variable: "" }}
Parameters:
- Delimiter: The delimiting string or regex on which to split the input text.
- Output Json: If true, outputs the split result as a JSON array. Otherwise, this sets the mAIstro variables for the resulting split.
- Variable: The base variable name to use for the array.
Returns: If Output Json is set to true, returns an array split based on your delimiter.
Example:
I have 20 cats and 40 dogs.
{{ splitDelim | delimiter: "cats" | outputJson: "true" | variable: "" }}
Would yield:
["I have 20 "," and 40 dogs.\n"]
Regular Expression
Performs regular expression on input data. Regular expression can be a powerful feature to extract or replace certain data.
{{ regex | match: "" | replace: "" | group: "" }}
Parameters:
- Match: The match regex to use. E.g.
/[^0-9A-Za-z\s]/g - Replace: The string to substitute for matches.
- Group: The group to extract. This is useful when multiple strings match the regex defined in the Match parameter, and you are only looking for one specific string.
Returns: The replaced text, or in case of using the group parameter, the group match.
Example 1:
If you have a text that you need to replace with something else, you can use the following expression:
my name is howardyoo
{{ regex | match: "yoo" | replace: "yu" }}
Which yields:
my name is howardyu
Example 2:
Regex also supports extraction. For example, if you want to extract the email address in a text message, you can do so:
my name is [email protected]
{{ regex | match: "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}" | group: "0" }}
This will extract the email address (group 0). The result is:
Example 3:
Regex also supports groups, so in case you want to get the last digits of a phone number, you can do so:
my phone number is 213-292-3322
{{ regex | match: "([0-9]+)-([0-9]+)-([0-9]+)" | group: "3" }}
which will result in:
3322
Escape a String
Escapes a string for use within a JSON object.
{{ jsonEscape }}
Parameters: None - Data should be "chained" into this function.
Returns: Escapes a string by inserting backslashes next to special characters, in order to overcome programming limitations.
Example:
"I saw my mother today, and I told her "I have 20 cats and 40 dogs"."
{{ jsonEscape }}
Would yield:
\"I saw my mother today, and I told her \"I have 20 cats and 40 dogs\".\"\n
