Zwei neue Funktionen pdf2txt und parseJson für Text-Extraktion aus PDF und parsen von JSON-Strukturen aus Text.

Die notwendigen externen Tools können auf einem Debian-System mit

apt install poppler-utils
apt install python3-pdfminer
apt install tesseract-ocr

installiert werden.

Test

• /com.top_logic.demo/src/test/java/test/com/top_logic/demo/scripted/tlscript/TestParseJson.script.xml

Für pdf2txt: Es werden externe Tools benötigt, die auf dem Applikationsserver installiert sein mussen: pdf2txt, pdftopmn, und tesseract.

Wenn diese Tools installiert sind, kann, z.B. der folgende Ausdruck ausgewertet werden:
