fit-serialize()

string fit-serialize(string|number|boolean|node-set argument [, boolean pretty-print = true()])

The XPath function fit-serialize generates a storable and human readable representation of the given node-set. For example, you could use this function to obtain a string representation of an XML DOM and log it via the fit-log() function for debugging.

If the type of the argument is scalar (string, number or boolean), the argument is cast to string and output as is.

If the pretty-print parameter is set to true() (which is the default), the fit-serialize function will try to generate nicely formatted output for a node-set. If set to false() the argument is output as is.

An empty node-set results in an empty string.

Examples

<flow>
  <default-request />
  ...
  <dump if="fit-log(fit-serialize(server))" />
  ...
</flow>

Example output of the server Delivery Context properties in the fit_engine.log:

[23-Mar-2017 06:56:33 UTC] WNNxoX8AAAEAAAMKKZQAAACW:myProject <server>
  <fit-version>14.6.3</fit-version>
  <project>myProject</project>
  <role>production</role>
  <site>mySite</site>
  <ucm>3dd4288fa57c4d192785d3dda3b05a73</ucm>
</server>

Using XSLT:

...
  <xsl:variable name="myVar">
    <foo>
      <bar>value</bar>
    </foo>
  </xsl:variable>
...
  <xsl:value-of select="fit-log(fit-serialize($myVar))" />
...

Example output in the fit_engine.log:

[27-Mar-2017 09:06:54 UTC] WNNxoX8AAAEAAAMKKZQAAACW:myProject  <?xml version="1.0"?>
<foo>
  <bar>value</bar>
</foo>
