One of the main features of the product I work on is data extraction from a specific type of PDF. If you want to build something similar these are my recommendations for you:
- Use a good text parsing library. Regexes are probably not enough for your use case. In case you are not aware of the limitations of regexes you may want to learn about Chomsky hierarchy of formal languages.
Here is the section of our Dockerfile that builds pdf2json for those of you that might need it:
# Download and install pdf2json
ARG PDF2JSON_VERSION=0.70
RUN mkdir -p $HOME/pdf2json-$PDF2JSON_VERSION \
&& cd $HOME/pdf2json-$PDF2JSON_VERSION \
&& wget -q https://github.com/flexpaper/pdf2json/releases/download/$PDF... \
&& tar xzf pdf2json-$PDF2JSON_VERSION.tar.gz \
&& ./configure > /dev/null 2>&1 \
&& make > /dev/null 2>&1 \
&& make install > /dev/null \
&& rm -Rf $HOME/pdf2json-$PDF2JSON_VERSION \
&& cd
- Use https://github.com/flexpaper/pdf2json to convert the PDF in an array of (x, y, text) tuples
