Merge the content of multiple XML files in SCML format.


scxmlmerge reads all SeisComP elements from one or more XML files in SCML format. It merges the content and prints the result to standard output. The input can contain and SeisComP element and the content can be filtered to print only some elements such as EventParameters. The output can be redirected into one single file and used by other applications.

The supported SeisComP elements are:

  • Config

  • DataAvailability

  • EventParameters

  • Inventory

  • QualityControl

  • Routing

By default all supported elements will be parsed and merged. Duplicates are removed. Use options to restrict the element types.

There are alternative modules for processing inventory XML files:

  • scinv: Merge inventory XML files, extract inventory information.

  • invextr: Extract and filter inventory information.


  1. Merge the all SeisComP elements from 2 XML files into a single XML file:

    scxmlmerge file1.xml file2.xml > file.xml
  2. Merge the all EventParameters and all Config elements from 2 XML files into a single XML file. Other element types will be ignored:

    scxmlmerge -E -C file1.xml file2.xml > file.xml
