Say I have the below xml string : 

<root>  
 <a>  
     <c>  </c>
 </a>

 <b>  </b>

</root>

Say i want immediate children of 'root' my approach :

  1. Extract tags inside root by using regex:

    extractedString = myXmlString.match(/<(\w+)([^>])>([\s\S])</\1>/g)[3]

  2. use a regex to get the child tags , but it gives me all the children i use this regex on the extracted string (i.e. the string between the root tags)

    childArray = extractedString.match(/<\w+/g)

but the above one also returns me c which is obvious , is there any way of extracting only a and b . or is this approach wrong? I am not looking forward to use any library please do correct me if my approach is wrong towards this (i.e. using regex) and suggest the correct way of doing this.

  • What is the language you are using? If it is JS, this post might be helpful: http://stackoverflow.com/questions/17604071/parse-xml-using-javascript – nhahtdh Nov 03 '14 at 10:14
  • It might be possible to do it by checking for a single TAB at the beginning of the line. – Bifrost Nov 03 '14 at 10:15
  • I am using javascript true but I do not want to use DOM parser am just trying this out as an exercise. So I want to know about the approach and code behind it. – Rishul Matta Nov 03 '14 at 10:19
  • @RishulMatta: If you are not using the DOM parser, then you are left with the option of reinventing the wheel or write a brittle regex that can break at the slightest change. – nhahtdh Nov 03 '14 at 10:20
