SlowCheetah transformations of QuartzNet config

问题

I am trying to set up transformation, using SlowCheetah, of a QuartzNet job configuration file. QuartzNet requires the xmlns attribute to be present on the job-scheduling-data node, but the presence of this attribute seems to stop SlowCheetah from running the transformations.

Simplified, this is what my scheduling config looks like:

<?xml version="1.0" encoding="UTF-8"?>
  <job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0">
<schedule>
<job>
  <name>Job1</name>
  <group>Group1</group>
  <description>Description</description>
  <job-type>MySample.MyJob, MySample</job-type>
</job>

<trigger>
  <cron>
    <name>DefaultTrigger</name>
    <job-name>Job1</job-name>
    <job-group>Group1</job-group>
    <cron-expression>0 0 4 * * ? *</cron-expression>
    <time-zone>GMT Standard Time</time-zone>
  </cron>
</trigger>
</schedule>
</job-scheduling-data>

The config transformation looks like this:

<job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform" >
<cron-expression xdt:Transform="Replace" xdt:Locator="XPath(/job-scheduling-data/schedule/trigger/cron/cron-expression[../name/text() = 'DefaultTrigger'])">"##DAILY_SCHEDULE##</cron-expression>
</job-scheduling-data>

The transformation doesn't work unless I either remove

xmlns="http://quartznet.sourceforge.net/JobSchedulingData"

from the original config file and the transformation file, or specify the namespace as, for example xmlns:ns1. The problem with either of these two approaches is that Quartz requires xmlns="http://quartznet.sourceforge.net/JobSchedulingData" to be present.

I have also tried using XPath expressions with local-name() in an effort to ignore the namespace in the expression syntax, but to no avail.

Any ideas how to get around this?

回答1:

It seems to me that your XPath expression should be:

/job-scheduling-data/schedule/trigger/cron/cron-expression[../job-name/text() = 'Job1']

Since it was matching name and not job-name.

The scary namespace-ignoring XPath expression below should also work:

/*[local-name()='job-scheduling-data']/*[local-name()='schedule']/*[local-name()='trigger']/*[local-name()='cron']/*[local-name()='cron-expression'][../*[local-name()='job-name']/text() = 'Job1']
