XSLT Transformation issue - how to populate attribute

I am using xslt first time. I have to 开发者_如何转开发create an element based on some criteria.

here is i/p xml:

<FirstUser>
   <User id="2" description="ABC" Type="HR"/>
</FirstUser>
<SecondUser>
  <User id="3" description="ABC" Type="HR"/>
  <User id="4" description="xyz" Type="Admin"/>
  <User id="5" description="LMN" Type="Payroll"/>
</SecondUser>

Final O/P

<AllUsers isFromHR='true'>
  <User id="2" description="ABC" Type="HR"/>
  <User id="3" description="ABC" Type="HR"/>
  <User id="4" description="xyz" Type="Admin"/>
  <User id="5" description="LMN" Type="Payroll"/>
</AllUsers>

Business Rule: AllUsers element has 1 attribute isFromHR - Its value w'd be true if value in type attribute of <FirstUser> or <SecondUser> is HR else it will be false

How to populate the value of isFromHR ? Rest of xml creation I am done.

Thanks in advance.

What about

<AllUsers isFromHR="{ count((//FirstUser | //SecondUser)[@type='HR']) &gt; 0 }">

or

<AllUsers>
    <xsl:attribute 
         name="isFromHR"
         value="count((//FirstUser | //SecondUser)[@type='HR']) &gt; 0" />

  <xsl:template match="/">
    <AllUsers>
      <xsl:attribute name="isFromHR">
        <xsl:choose>
            <xsl:when test="//*[local-name(.)='FirstUser' or local-name(.)='SecondUser']/*/@Type[.='HR']">true</xsl:when>
        <xsl:otherwise>false</xsl:otherwise>
      </xsl:choose>
        </xsl:attribute>
      <xsl:apply-templates />
    </AllUsers >
  </xsl:template>

<AllUsers isFromHR="{descendant::@type = 'HR'}">

The input XML is missing elements:

<FirstUser>
   <User id="2" description="ABC" Type="HqR"/>
</FirstUser>
<SecondUser>
  <User id="3" description="ABC" Type="H2R"/>
  <User id="4" description="xyz" Type="Admin"/>
  <User id="5" description="LMN" Type="Payroll"/>
</SecondUser>

In any case, I'd go for:

<AllUsers isFromHR="{//FirstUser/User/@Type = 'HR' or //SecondUser/User/@Type = 'HR'}">

This gives you "true" in case either FirstUser or SecondUser contains a User of type 'HR'.
