HOWTO: Parsing multiple IPTC data

Hi,

I'm extracting the IptcKeyword field from the following image:

http://www.getjealous.com/01_sRGB.jpg

There are multiple keywords for the image:

black and white
blonde
classic
fireplace
floor
interior
living room
romantic
Sheller
terrace house
timber
timber floor
white

When I get the keywords out of the request (using php: $HTTP_POST_VARS[IptcKeyword_1]) they are one long string, with each keyword seperated by a string:

black and white blonde classic fireplace floor interior living room romantic Sheller terrace house timber timber floor white

Since there are keywords with spaces, there is no way to find out what they individual keywords are. Is there anyway to get this list. Is there any way you know that I can get around this so that i can loop through each keyword?

Thanks,

George

Thanks Fedor,

I have achieved this by parsing the image on the server side. For anyone else using Java who needs to acomplish this, you can use the MetaData Extraction library from http://www.drewnoakes.com/code/exif/ and the following code:


File jpegFile = new File("C:/stuff/My Documents/Content/01_adobeRGB.jpg");
try {

Metadata metadata = JpegMetadataReader.readMetadata(jpegFile);

// iterate through metadata directories
Iterator directories = metadata.getDirectoryIterator();
while (directories.hasNext()) {

Directory directory = (Directory) directories.next();

if (directory.containsTag(IptcDirectory.TAG_KEYWORDS)) {

try {

for (String s:directory.getStringArray(IptcDirectory.TAG_KEYWORDS)) {

System.out.println(s);
}
} catch (MetadataException e) {

e.printStackTrace();
}
}
}

} catch (JpegProcessingException e) {

e.printStackTrace();
}

Now the ImageUploader.MetaDataSeparator property can be used to define separator symbol for multiple tags.
