# -*- coding: utf-8 -*- obspy.xseed - Dataless SEED, RESP and XML-SEED read and write support for ObsPy =============================================================================== `XML-SEED` was introduced by Tsuboi, Tromp and Komatitsch (2004), it is a XML representation of `Dataless SEED`. This module contains converters from `Dataless SEED` to `XML-SEED` and vice versa as well as a converter from `Dataless SEED` to `RESP` files. The :mod:`~obspy.xseed` module is tested against the complete ORFEUS Dataless SEED archive, the IRIS (US) Dataless SEED archive and against ArcLink response requests.

Allocate a Parser object and read/write ---------------------------------------
>>> from obspy.xseed import Parser >>> sp = Parser("/path/to/dataless.seed.BW_FURT") >>> sp.writeXSEED("dataless.seed.BW_RJOB.xml") #doctest: +SKIP
The lines above will convert `Dataless SEED`, e.g.::
000001V 010009402.3121970,001,00:00:00.0000~2038,001,00:00:00.0000~ 2009,037,04:32:41.0000~BayernNetz~~0110032002RJOB 000003RJOB 000008 ...
to the `XML-SEED` representation, e.g.::
<?xml version='1.0' encoding='utf-8'?> <xseed version="1.0"> <volume_index_control_header> <volume_identifier blockette="010"> <version_of_format>2.4</version_of_format> <logical_record_length>12</logical_record_length> <beginning_time>1970-01-01T00:00:00</beginning_time> <end_time>2038-01-01T00:00:00</end_time> <volume_time>2009-02-06T04:32:41</volume_time> <originating_organization>BayernNetz</originating_organization> ...
A response file can be written in a similar manner, just replace :meth:`~obspy.xseed.parser.Parser.writeXSEED` by :meth:`~obspy.xseed.parser.Parser.writeRESP`:
>>> sp.writeRESP(folder="BW_FURT", zipped=False) #doctest: +SKIP
The Parser Object -----------------
`SEED` files as well as its derived format `XML-SEED` will be parsed in a :class:`~obspy.xseed.parser.Parser` structure.
`SEED` volumes have four different volume types:
* Volume Index Control Headers * Abbreviation Dictionary Control Headers * Station Control Headers * Time Span Control Headers (currently not supported by ObsPy. Some dummy headers will be written in case they are needed by SEED/XSEED conventions.)
After parsing a `SEED` or `XML-SEED` file the Blockette objects for each volume will be stored in the attributes``Parser.volume``, ``Parser.abbreviations`` and ``Parser.stations``. Each item is a list of all related Blockettes and ``Parser.stations`` is a list of stations which contains all related Blockettes. """
