| # input_transform.sh |
| # sample input transformation, demonstrating use of Java and Joost STX |
| # to convert MeF XML into escaped text suitable for loading into GPDB. |
| # |
| # java arguments: |
| # -jar data/joost.jar joost STX engine |
| # -nodecl don't generate an <?xml?> declaration |
| # $1 (or -) filename to process (or stdin) |
| # mef/input_transform.stx STX transformation |
| # |
| # This first step extracts interesting attributes from the input document |
| # (the "id" column in this example). |
| # |
| java \ |
| -jar data/joost.jar \ |
| -nodecl \ |
| $1 \ |
| mef/input_transform.stx | \ |
| awk 'NF>0 {printf "%s|", $0}' |
| |
| # This second awk command escapes newlines in the input document before |
| # sending it to GPDB so that the entire document ends up in our xml 'doc' column. |

| awk '{ printf "%s\\n",$0 }' $1 |
