Hi folks,
I'm a student working on my bachelor thesis. I use BaseX to read large XML files and forward them to a PostgreSQL database. Additionally I want to fetch images via URI and add them to the database-records. While fetching these images, I have to test three different file extensions for each image, as my source does not use one single image format (but jpg, png and gif). First I tried checking with fn:doc-available($uri) weather that certain URI is available, but this obviously only works for XML-documents. Then I wanted to catch the err:BXFE0001 that is thrown by fetch:binary($uri), but this does not work, either; the error-message is displayed and the script stops. > declare variable $baseuri := 'http://www.bricklink.com/ML/'; > declare variable $itemid := 'sw008'; > > try { > fetch:binary($baseuri || $itemid || '.png') > } > catch err:BXFE0001 { > try { > fetch:binary($baseuri || $itemid || '.gif') > } > catch err:BXFE0001 { > try { > fetch:binary($baseuri || $itemid || '.jpg') > } > catch err:BXFE0001 { > 0 > } > } > } In this example, only the .jpg-image exists. But all I get is > [BXFE0001] Resource "http://www.bricklink.com/ML/sw008.png"; not found. > Information: > <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" > "http://www.w3.org/TR/html4/strict.dtd";> > <HTML><HEAD><TITLE>The page cannot be found</TITLE> … and so on I would be very glad if you could help me with this, either by pointing out my coding-error or by showing me another, better solution for doing this. Thank you and have a nice day, Alex PS: My sources on Try/Catch and fetching -- | Alexander von Bernuth | [email protected]
