This XQuery Module contains functions to handle ZIP archives. New ZIP archives can be created, existing archives can be updated, and the archive entries can be listed and extracted. This module may eventually replace the existing ZIP Module as soon as it is finalized and adopted by other XQuery implementations.
Conventions
All functions in this module are assigned to the http://basex.org/modules/zip2
namespace, which is statically bound to the zip2
prefix.
All errors are assigned to the http://basex.org/errors
namespace, which is statically bound to the bxerr
prefix.
Functions
zip2:create
Signatures | zip2:create($entries as element(entry)*, $contents as item()*) as xs:base64Binary |
Summary | Creates a new ZIP archive from the specified entries and contents. The $entries elements contain meta information required to create new ZIP entries. Beside the mandatory entry name, optional attributes can be specified, which contain the timestamp, compression level and encoding of textual entries. An Example:
<entry last-modified='2011-11-11T11:11:11' compression-level='9' encoding='US-ASCII'>hello.txt</entry> The actual |
Errors | FOZ20001 : the number of entries and contents differs.FOZ20002 : (some of) the contents are not of type xs:string or xs:base64Binary .FOZ20003 : entries elements contain invalid data.FOZ20004 : the specified encoding is invalid or not supported.FOZ29999 : archive processing failed for some other reason.
|
Examples | The following function creates an archive archive.zip with one file file.txt :
zip2:create(<entry>file.txt</entry>, 'Hello World') |
