Changes the <meta name="productname"> content

[tomschr]

In an assembly file, you can add or remove <productname> elements from <meta name="productname">.

The stylesheet CAN NOT preserve entities! This needs to be done outside, usually with sed.

The stylesheet contains several checks:

• Checks if the root element is an <assembly> element and belongs to the DocBook 5 namespace.
  If not, the stylesheet returns an error messages and refuses to continue.
• Checks if the required XSLT parameters version, product, and op are set.
  If not set, the stylesheet returns an error message and refuses to continue.
• Checks if there are more than one <structure> element.
  If yes, it's expected that the structure.id parameter points to the ID. If not, the stylesheet returns a error message and refuses to continue.
• Checks if the ID of the <structure xml:id="ID"> is there.
  If not, the stylesheet returns a error message and refuses to continue
• Checks, if there is a <meta name="productname"> element.
  If not, the stylesheet returns a warning and continues.
• When op = "add" and there is already a <productname> with the same content, return a warning and continue
• When op = "remove" and there is no <productname> with the requested content, return a warning and continue.

Examples

Adding content

$ xsltproc --stringparam op add \
           --stringparam version "16-SP1" \
           --stringparam product "SLES" \
           $DAPS_PATH/daps-xslt/contrib/change-products-on-assembly.xsl \
           articles/Micro-upgrade.asm.xml

Removing content

You can also use remove or r for the op XSLT parameter:

$ xsltproc --stringparam op rm \
           --stringparam version "16-SP1" \
           --stringparam product "SLES" \
           $DAPS_PATH/daps-xslt/contrib/change-products-on-assembly.xsl \
