## DESCRIPTION

### The String Parser is used to search and replace substrings.

## OCCURRENCE

### TREE/Species/Search:PARSE FIELD

### TREE/Properties/NDS

## SYNTAX

    'search=replace'        means search all occurrences of 'search'
                            and replace it by 'replace'

### Different search/replace commands can be separated by ':':

'search1=replace1:search2=replace2: ... :searchn=replacen'

## SPECIAL CHARACTERS

### Search && Replace string:

    ':'                separates two commands
    '='                separates the search from the replace string
    '\'                Escape symbol
    '\\'               the '\' symbol itself
    '\n'               newline
    '\t'               tabulator
    '\:'               ':'
    '\='               '='
    '\?'               '?'
    '\*'               '*'

### Search string:

    '?'                single letter wildcard
    '*'                multi letter wildcard

### Replace string:

    '?'                a reference to the corresponding single
                       letter wildcard in the search string
                       (if no digit or '(' follows).
    '?n'               n = { 1,...,9 }
                       a reference to the n'th single letter wildcard
                       in the search string
    '*'                a reference to the corresponding multi
                       letter wildcard in the search string
                       (no digit or '(' follows).
    '*n'               n = { 1,...,9 }
                       a reference to the n'th multi letter wildcard
                       in the search string
    '*(key)'           the value of a database field named <key>
                       if this field does not exits then the string ''
    '*(key#mystring)'  the value of a database field named <key>
                       if this field does not exits then the string 'mystring'
    '*(key\:nsrt)'     invokes the SRT recursively on the value of the
                       database field 'key'
                       NOTE: All ':' have to be 'escaped'
    '*([key]|ACI)'     starts ACI (see ´ARB Command Interpreter (ACI)´)
                       on the value of '[key]' (which may be empty).

## EXAMPLES

### 'p?r=p?w'

    replaces all    par to paw
                    pbr to pbw
                    pcr to pcw ...

### 'p??r=p?2?1r'

swaps the two letters between p and r

### 'a*=b*'

replaces only the first 'a' by 'b'

### '?* *=?. *2'

Replaces the first word by its first letter + '.'

### '\:=\n'

replaces all ':' by <newline>

### '*=* *(key1)'

appends the database field <key1>. if <key1> does not exists append nothing

### '*=* *(key1#no info)'

appends the database field <key1> if <key1> does not exists append 'no info'

### '*=*(key2\: =)'

The value of 'key2' with all spaces removed

### '*=*(key2|remove(.-))'

the value of the database entry 'key2', but all '.' and '-' characters removed

## WARNINGS

### Be careful when search or replace string contain special characters (such as ':'). Avoid to write too complicated commands.

## BUGS

### None
