XML tagname starting with number is not working

Question

I want to update the component 870Jars atrribute values using Jenkins build. When i open the xml file in IE, I am getting the below error

Error:- The XML page cannot be displayed

Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.

A name was started with an invalid character. Error processing resource 'https://svn.retailerinfo.com/svn/Stores/Po...

<870Jars> ---^

XML file:-

<?xml version="1.0" encoding="UTF-8"?><Application> 
<app-name>Regist</app-name>
<baseline-version>Regist_R11.6.0.51</baseline-version>
<app-version>v11.6.0.51</app-version>
<defversion>1.0.0</defversion>
<component>
    <870Jars>
    <filename>v10.3.0-870Jars.zip</filename> 
    <targetfilename/> 
    <version>v10.3.0</version> 
    </870Jars>
</component>
</Application>

Is there any way where i can start a tag name with a number ?

I used </870Jars> in place of <870Jars> but it is just printing the value rather than working as tag

Answer 1

An XML element whose name starts with a number is illegal XML. You should not start with numbers.

XML elements must follow these naming rules:

• Names can contain letters, numbers, and other characters
• Names cannot start with a number or punctuation character
• Names cannot start with the letters xml (or XML, or Xml, etc)
• Names cannot contain spaces

Any name can be used, no words are reserved.
