Oracle APEX: How to extract text from inside a PDF or Word Doc
In this video we will show you how to quickly extract all the text from inside a pdf or word document and store the information inside a CLOB for quick retrieval.
Our video begins with a table containing a BLOB column with several pdf's and .doc's. We will start by creating a filter on the table to index the documents leveraging CTXSYS.CONTEXT and CTXSYS.AUTO_FILTER.
Next we will create a table with a CLOB column to store the text inside of the pdf. Once created we showcase a short segment of code leveraging the ctx_doc.filter API to process all the BLOBs extracting the raw text into the CLOB.
With the information inside a CLOB Oracle APEX can now easily display and process the text to users at a fraction of the time it would take to display or download the BLOB.
