TrimFromEnd, TrimFromStart, TrimToEnd and TromToStart
These four rules all remove some text from the source container. They all take the same parameter, SearchText. The rules differ in whether they trim the beginning or end of a string, and whether or not they include the SearchText value in the result.
Parameters:
•SearchText: The first occurrence of this string will form the basis of the trimming.
Examples:
Suppose the Source container contains "Mary had a little lamb". The following rule places " little lamb" (note the leading space!) in the MaryStuff container.
<ParsingRule Type="TrimToEnd" Source="Source" Result="MaryStuff"> <SearchText>had a</SearchText>
</ParsingRule>
The following rule places "ry had a little lamb" (everything after the first "a") in the MaryStuff container.
<ParsingRule Type="TrimToEnd" Source="Source" Result="MaryStuff"> <SearchText>a</SearchText>
</ParsingRule>
The following rule places "Mary " (note the trailing space!) in the MaryStuff container.
<ParsingRule Type="TrimFromStart" Source="Source" Result="MaryStuff"> <SearchText>had a</SearchText>
</ParsingRule>
The following rule places "M" (everything before the first "a") in the MaryStuff container.
<ParsingRule Type="TrimFromStart" Source="Source" Result="MaryStuff"> <SearchText>a</SearchText>
</ParsingRule>
