Hi, I have a problem with key specification for cwb-align-import tool. I have corpus with two structural tags. Sample file might look like this: <file id="filename"> <s num="1"> Hello World ! </s> </file> I'd like to use key consisting both from file id and s num. Any ideas how I could achieve this with cwb-align-import tools (in aligment file) Bests, Konrad Goluchowski
