Java XML parsing.

Whats the quickest way to convert a doc like:

<customermodel:Customer>
    <creditCards>
     <cardNumber>@0</cardNumber>
     <provider>@HSBC</provider>
     <xsi:type>@customermodel:CreditCard</xsi:type>
             23242552
    </creditCards>
    .
    .

So that the elements with @ become attributes for the parent element.

ie get to:

<customermodel:Customer>
    <creditCards cardNumber="0" provider="HSBC" xsi-type="customermodel:CreditCard>
         232323232
    </creditCards>
        .
        .

Using a dom? or Sax parser or manually? and i can move the @ into the <>'s

From stackoverflow

• The best way to work directly with XML data is to use XQuery. It is not the easiest thing to learn, but if you work a lot with XML it is very useful.

  Some IDE even support XQuery editing (like Oxygen XML).

• I think XSLT is the way to go.

  And use a SAX parser, unless you have very good reasons.

• If you decide to use XSLT, it will look something like

    <!-- process element and attributes first so that whitespace doesn't interfere -->
    <xsl:template match="creditCards">
      <xsl:copy>
        <xsl:apply-templates select="* | @*"/>
        <xsl:apply-templates select="text()"/>
      </xsl:copy>    
    </xsl:template>
  
    <!-- change childrent of creditCards to attributes and strip first charcter from value -->
    <xsl:template match="creditCards/*">
      <xsl:attribute name="{name()}">
        <xsl:value-of select="substring(., 2)"/>
      </xsl:attribute>
    </xsl:template>
  
    <!-- rename xsi:type -->
    <xsl:template match="creditCards/xsi:type">
      <xsl:attribute name="xsi-type">
        <xsl:value-of select="substring(., 2)"/>
      </xsl:attribute>
    </xsl:template>
  
    <!-- identity transform -->
    <xsl:template match="node() | @*">
      <xsl:copy>
        <xsl:apply-templates select="node() | @*"/>
      </xsl:copy>
    </xsl:template>
