XML stands for eXtensinble Markup Language. It is very similar to HTML except it doesn't have any predefined tags. It's a meta language that allows you to define your own markup language which then can be used to store and share data in a structured manner.


A Prisjakt offer feed should use two namespaces, the g namespace which most fields belong to that are defined by the Google Product Specification and then the pj namespace which contains some additional Prisjakt specific fields defined by us.


<rss xmlns:pj="" xmlns:g="" version="3.0">


<rss xmlns:pj="" xmlns:g="" version="3.0">

Namespace Priority When Parsed

If multiple fields with the same name but different namespaces exist, the field will be parsed with the following priority:

  1. pj: first eg. <pj:some_field>Some pj field</pj:some_field>
  2. g: second eg. <g:some_field>Gome g field</g:some_field>
  3. no namespace third eg. <some_field>Some field</some_field>
  4. other/unknown in undefined order eg. <xyz:some_field>Some xyz field</xyz:some_field>


Use UTF-8

All XML feeds should start with the following header and the files should be properly UTF-8 encoded.

Do not use control characters in feed file. We support some of them trying to follow XML spec but not guarantee to fully support it.

<?xml version='1.0' encoding='UTF-8'?>


You should lower the risk of your data causing xml parsers to fail because of invalid data by encoding your data correctly. Take a look on our CDATA article to achieve this.
