Extract Data from Invoices to XML or CSV?

Hi Community,

I’m trying to understand if the basic version of KNIME as an open-source solution meets my requirements and is the right tool for me or not. We receive digital PDF security invoices and want to extract specific information from these invoices (account number, security number, price, price value…) and output them as CSV or XML files. Unfortunately, these are not proper tables but are more or less always presented as free text somewhere and somehow on the forms. Additionally, there are dozens of banks, each sending completely different invoices, which makes it difficult, in my opinion, to write individual regex patterns for hundreds of banks. A tool that can learn or guess parameters from new banks would be a significant relief. Can KNIME do this in any way, or am I completely off track here? Thanks!
