I want to replace a string such "how r u" in file test.xml with a string "i am fine" in another file xy.xml.using regular expression in ms build.
ie i have to read string from one file(xy.xml) and replace it in another file test.xml. so please provide necessary steps to solve this issue with example
EDIT: This answer is obsolete. Use solution below...
Use ReadLinesFromFile task to get replacement string from the xy.xml file. Check this
Then use value from xy.xml as a replacement string for FileUpdate task. Check this
And put it all together ;)
