"[SOLVED] Separating CapitalizedString into single words"

monami555

Hi all

I have been trying for quite a long time  to solve the following problem but cannot find any way, maybe someone had a similar issue:

I have a set of examples which have attribute values like:

"CapitalizedStringIntoSingleWords"

but I want them in the form of "Capitalized String Into Single Words" (separate them by capital letter, I don't mind if the result words are capitalized or not). I could use Regular Expressions, I can easily filter out the capital letters, but then I get only something like:

" apitalized tring nto ingle ords"

... huh, that seems to be a more general problem, and I cannot get my thinking out of the box..  :-[
Any ideas, help? ???

Cheers,
Monika

Hi,

you can use the operator Replace with a reg exp and capturing groups like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.1.017">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="5.1.017" expanded="true" name="Process">
    <process expanded="true" height="145" width="413">
      <operator activated="true" class="generate_data_user_specification" compatibility="5.1.017" expanded="true" height="60" name="Generate Data by User Specification" width="90" x="45" y="30">
        <list key="attribute_values">
          <parameter key="text" value="&quot;CapitalizedStringIntoSingleWords&quot;"/>
        </list>
        <list key="set_additional_roles"/>
      </operator>
      <operator activated="true" class="replace" compatibility="5.1.017" expanded="true" height="76" name="Replace" width="90" x="179" y="30">
        <parameter key="attribute_filter_type" value="single"/>
        <parameter key="attribute" value="text"/>
        <parameter key="replace_what" value="([A-Z])"/>
        <parameter key="replace_by" value=" $1"/>
      </operator>
      <operator activated="true" class="trim" compatibility="5.1.017" expanded="true" height="76" name="Trim" width="90" x="313" y="30">
        <parameter key="attribute_filter_type" value="single"/>
        <parameter key="attribute" value="text"/>
      </operator>
      <connect from_op="Generate Data by User Specification" from_port="output" to_op="Replace" to_port="example set input"/>
      <connect from_op="Replace" from_port="example set output" to_op="Trim" to_port="example set input"/>
      <connect from_op="Trim" from_port="example set output" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>

The operator "Trim" is just for removing the first space if there is one. If this is not desired, you could also define the reg exp in a way that only Capitals not at the start of the line will be replaced. This looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.1.017">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="5.1.017" expanded="true" name="Process">
    <process expanded="true" height="145" width="413">
      <operator activated="true" class="generate_data_user_specification" compatibility="5.1.017" expanded="true" height="60" name="Generate Data by User Specification" width="90" x="45" y="30">
        <list key="attribute_values">
          <parameter key="text" value="&quot;CapitalizedStringIntoSingleWords&quot;"/>
        </list>
        <list key="set_additional_roles"/>
      </operator>
      <operator activated="true" class="replace" compatibility="5.1.017" expanded="true" height="76" name="Replace" width="90" x="179" y="30">
        <parameter key="attribute_filter_type" value="single"/>
        <parameter key="attribute" value="text"/>
        <parameter key="replace_what" value="((?&lt;!^)[A-Z])"/>
        <parameter key="replace_by" value=" $1"/>
      </operator>
      <connect from_op="Generate Data by User Specification" from_port="output" to_op="Replace" to_port="example set input"/>
      <connect from_op="Replace" from_port="example set output" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>

The reg exp for the parameter "replace what" is '((?<!^)[A-Z])' (without the quotes), and the reg exp for "replace by" is ' $1' (note the leading space).

Hope that helps,
Ingo
