With the help of absolute path and relative path my question is how i will get into testing element then i have to select import element from there.

Actually, there is no need to specify a complete path to testing and check that it has an import child.

The XSLT processing model (built-in templates), combined with your templates and proper template match patterns, does the navigation for you.

The built-in templates are selected for execution if there is no explicit template that matches a particular node. he cumulative result of applying the built-in templates is that the document tree is traversed and only text nodes are output.

One can specify templates to override the built-in ones only for nodes that should be processed in a different, specific way. When the built-in templates apply templates for a child of a node and there is explicit (user-provided) template matching that node, this explicit template is selected for execution/processing of that node.

This short XSLT 1.0 transformation:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:template match="/">
     <maindocument>
        <xsl:apply-templates/>
     </maindocument>
 </xsl:template>

 <xsl:template match="import/downloading">
  <import>
    <doctype><xsl:value-of select="substring-before(., ' ')"/></doctype>
    <docint><xsl:value-of select="substring-after(., ' ')"/></docint>
  </import>
 </xsl:template>
 <xsl:template match="text()"/>
</xsl:stylesheet>

when applied on the provided XMLdocument:

<maindocument>
    <first>
        <testing>random text</testing>
        <checking>random test</checking>
    </first>
    <testing>
        <testing>sample</testing>
        <checking>welcome</checking>
        <import>
            <downloading>valuable text</downloading>
        </import>
    </testing>
</maindocument>

produces the wanted, correct result:

<maindocument>
   <import>
      <doctype>valuable</doctype>
      <docint>text</docint>
   </import>
</maindocument>
