replaceregexp ant not inserting tabulation - regex

Question

I want to replace a tabulation when I have a match in a file. I have this code:
<property name="line.separator" location="\r" />
<property name="tab.separator" location="\t" />
<target name="replace">
<replaceregexp
match='#WebMethod([\s\S]*?(?=public))public\s+(\w+)\s+(\w*)[\s\S]+?(?=\))[\s\S]+?(?=MSE)(\w+)\s+(\w*)[\s\S+]+?(?=throws)throws\s+(\w*)'
replace='#WebMethod(operationName="\$4")${line.separator}${tab.separator}#RequestWrapper(localName = "\$3")${line.separator}\r#ResponseWrapper(localName = "\$2")${line.separator}\rpublic \$2 \$3\(${line.separator}\r\r\$4 \$5)${line.separator}\r\rthrows MSFWebServiceException' flags="g,m">
<fileset dir="${project.dir}" />
</replaceregexp>
But the part of
#WebMethod(operationName="\$4")${line.separator}${tab.separator}#RequestWrapper
returns this:
#WebMethod(operationName="MSEPDetalleFigPartDTO")
C:t#RequestWrapper
So the \n goes ok, but the \t doesn't work because it replace the \t with C:t instead of a tabulation.
Any help would be appreciate.
kindest regards

Answer 1

This is cause by location instead of value and \t instead of :
<property name="tab.separator" location="\t" />
instead of
<property name="tab.separator" value=" " />
The property line.separator is already set (because it is an Ant built-in property), so your first line is just ignored.
location="\t" means the file location of the file t in the root directory, in your case it is the drive C:
