Hi, Matt
thx for your suggestion!
Well, the txtfile i have to alter has actually >40 lines
so with your solution i would have a lot of <echo ...</echo>
And there's also another detail i forgot to mention.
The pattern 'bla' exists 2 times in that txtfile.
the first match is
...
bla
1234
...
and some lines below its :
...
bla
...
So the second match is always followed by a blank line.
That blank line after the second match has to be filled with
a property i get of another script.
The solution must be something like :
<copy file="${mytxtfile}" toFile="newtxtfile">
<filterchain>
<tokenfilter>
<replaceregex pattern="(bla\r\n)(\s\r\n)" replace="helloworld\2"
flags="gm"/>
</tokenfilter>
</filterchain>
</copy>
-> i don't know the exact syntax here ?!,
first group should be the pattern itself, followed by a linebreak,
second group the next (blank) line.
When running, ant shows no syntax error, but the file stays the same.
I've tried with and without flag multiline.

All you have to match is the line break count, so assuming you know what
those are (use fixcrlf worst
case) tokenfilter + filetokenizer + replaceregex works. My
self-contained example (with Jakarta ORO as my regexp engine):
<project>
<property name="br" value="${line.separator}" />
<property name="insert" value="hello world" />
<echo file="foo.txt" append="false">01 bla${br}</echo>
<echo file="foo.txt" append="true">02
bla${br}</echo>
<echo file="foo.txt" append="true">03
bla${br}</echo>
<echo file="foo.txt" append="true">04 ${br}</echo>
<echo file="foo.txt" append="true">05 ${br}</echo>
<echo file="foo.txt" append="true">06 ${br}</echo>
<echo file="foo.txt" append="true">07
bla${br}</echo>
<echo file="foo.txt" append="true">08
bla${br}</echo>
<echo file="foo.txt" append="true">09
bla${br}</echo>
<copy file="foo.txt" tofile="bar.txt">
<filterchain>
<tokenfilter>
<filetokenizer />
<replaceregex
pattern="^(.*${br}.*${br}.*${br}.*)(${br}.*)"
replace="\1${insert}\2" />
</tokenfilter>
</filterchain>
</copy>
</project>
