a simple problem

Hi all,

I know my question is very basic. I am a newbie and couldn't find a similar code.
I have the original xml like this:
<gxl>
     <graph>
             <node id="0"
                    <attr name = "label">
                            <string>something</string>
                    </attr>
                    <attr name = "font"
                     ...
              </node>
              <node id =
               ...
      </graph>
</gxl>

And I'd like to make an xslt to output an xml like
<state>
      <Name>Node id</Name>
      <Condition>something</Condition>
</state>
<state>
..
</state>

I mean i want to get the Node id to place in the <Name> tag of state.
Each Node is a State in my out xml. If the attr name of Node is label, I get the string and put in tag Condition.
How can I do that ?

Please help me with this small example.
Thank you very much !
Suzy.

Well if your xml is

Code:

<gxl>
  <graph>
    <node id="0">
      <attr name="label">
        <string>label0</string>
      </attr>
      <attr name="font">
        <string>font</string>
      </attr>
    </node>             
    <node id="1">
      <attr name="label">
        <string>label1</string>
      </attr>
      <attr name="font">
        <string>font</string>
      </attr>
    </node>             
    <node id="2">
      <attr name="font">
        <string>font</string>
      </attr>
    </node>             
    <node id="3">
      <attr name="label">
        <string>label3</string>
      </attr>
      <attr name="font">
        <string>font</string>
      </attr>
    </node>             
  </graph>
</gxl>

then you want something along the lines of

Code:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/">
    <states>
      <xsl:apply-templates select="gxl/graph/node"/>
    </states>
  </xsl:template>

  <xsl:template match="node">
    <state>
      <name><xsl:value-of select="@id"/></name>
      <xsl:if test="attr[@name = 'label']">
        <condition><xsl:value-of select="attr[@name = 'label']/string"/></condition>
      </xsl:if>
    </state>  
  </xsl:template>
</xsl:stylesheet>

which selects all the node eleemnts and adds the surrounding markup. There is also a conditional test for an attr with a attribute name of label.
