Insert xml after any element in needed order

[marcencov]

Hi.

Can you realize to add new element after 1 or for example after 3?

For example

<modules> <module>1</module> <module>3</module> </modules>

I need to insert after 1 and before 3.

Thanks.

Hi there -- this looks possible. What XPath expression have you tried?

[marcencov]

I'm not understand how realize this inserting. Can you help?

[martinb3]

Hello! Can you show a before and after? I'm happy to help troubleshoot, but please show us what you have already tried too.

Closing since I haven't gotten a response.

Example.

Input: <modules><module>1</module><module>3</module></modules> (I have 1,3).

I need insert after 1, before 3 (must receive output
<modules><module>1</module><module>2</module><module>3</module></modules>
).

If I use append and prepend: false I receive: <modules><module>1</module><module>3</module><module>2</module></modules> - not correct order 1,3,2.

If I use append and prepend: true I receive: <modules><module>1</module><module>3</module><module>2</module></modules> - not correct order 2,1,3.

How I can receive 1,2,3 in correct order <modules><module>1</module><module>2</module><module>3</module></modules> (append after 1 and before 3)?

Please show us the exact chef code you've tried 👍

Input xml:

<?xml version="1.0" encoding="UTF-8"?>
<Root version="2">
  <Server>
    <Modules>
    </Modules>
  </Server>
</Root>

Input chef:

include_recipe 'xmledit'

 xml_edit "test_append1" do
   path "/home/msasha/test.xml"
   parent '/Root/Server/Modules'
   target "/Root/Server/Modules/Module[Name=\'module1\']"
   fragment "<Module>
               <Name>module1</Name>
             </Module>"
   action :append_if_missing
 end

 xml_edit "test_append2" do
   path "/home/msasha/test.xml"
   parent '/Root/Server/Modules'
   target "/Root/Server/Modules/Module[Name=\'module2\']"
   fragment "<Module>
               <Name>module2</Name>
             </Module>"
   action :append_if_missing
 end

 xml_edit "test_append4" do
   path "/home/msasha/test.xml"
   parent '/Root/Server/Modules'
   target "/Root/Server/Modules/Module[Name=\'module4\']"
   fragment "<Module>
               <Name>module4</Name>
             </Module>"
   action :append_if_missing
 end

 xml_edit "test_append5" do
   path "/home/msasha/test.xml"
   parent '/Root/Server/Modules'
   target "/Root/Server/Modules/Module[Name=\'module5\']"
   fragment "<Module>
               <Name>module5</Name>
             </Module>"
   action :append_if_missing
 end

After execute I receive modules in order: module1, module2, module4, module5.
How I can insert next 'module3' after module2 and before module4?

Thanks

Have you tried something like?

 xml_edit "test_append3" do
   path "/home/msasha/test.xml"
   parent '/Root/Server/Modules'
   target "/Root/Server/Modules/Module[Name=\'module2\']"
   fragment "<Module>
               <Name>module2</Name>
             </Module>
             <Module>
               <Name>module3</Name>
             </Module>"
   action :replace
 end

Martin - I've run 2 times chef-client and recive next:
every time that I run chef-client this changes applied.
module3 - 2 times and more....

<?xml version="1.0" encoding="UTF-8"?> <Root version="2"> <Server> <Modules> <Module> <Name>module1</Name> </Module> <Module> <Name>module2</Name> </Module> <Module> <Name>module3</Name> </Module> <Module> <Name>module3</Name> </Module> <Module> <Name>module4</Name> </Module> <Module> <Name>module5</Name> </Module> </Modules> </Server> </Root>

You probably need to add an only_if or not_if to that resource, to prevent insertion too many times, if you only want it to happen once. Maybe not_if 'grep module2 /home/msasha/test.xml'?
