concat, quotation mark and apostrophe combination problems

Question

I tried different ways and also looked around but can\'t get this running. I need to concat the following:

\"concat( 
    \'this is; \\\"a sample\',
    //XM         


        

Answer 1

No variable is necessary:

Here is an example how to produce the wanted output in two ways:

 

 
  this is "a sample XML_NODE_VALUE"; "using an apostrophe ' in text"
  =============
  
 

When this transformation is applied on any XML document (not used), the wanted output is produced:

this is "a sample XML_NODE_VALUE"; "using an apostrophe ' in text"
=============
this is "a sample XML_NODE_VALUE"; "using an apostrophe ' in text"
