hi!

generic xml:
<obrazac>
<odjeljak sifra="G.5">
    <red num="1">
      <text id="1">neki text</text>
    </red>
    <red num="2">
      <stupac>
        <checkbox id="5-1">text koji ide sa checkboxom</checkbox>
      </stupac>
      <stupac>
        <text id="5-2">sfdgygasg</text>
        <br />
        <unos id="5-3" />
      </stupac>
    </red>
  </odjeljak>
  <odjeljak sifra="G.6" />
</obrazac>

other xml:, i have 20 xml like this. structure is sabe, but elements are in
different order
<obrazac>
  <odjeljak>
    <text>sudjelovanje</text>
    <br />
    <text>Datum: </text>
    <unos id="29" />
    <text>vrijeme: </text>
    <unos id="30" />
  </odjeljak>
  <odjeljak sifra="G.5" />
  <odjeljak>
    <text>Ostali: </text>
    <unos id=".31" />
  </odjeljak>
  <odjeljak>
    <text>ponuda</text>
    <br />
    <text>Datum: </text>
    <unos id="32" />
    <br />
    <checkbox id="C.14">Da</checkbox>
    <checkbox id="C.15">Ne</checkbox>
    <br />
    <unos id="35" />
  </odjeljak>
  <odjeljak sifra="I.1">
    <redovi od="1" do="7" />
  </odjeljak>
</obrazac>

all i just want is to go trough other xml and check <odjeljak> for attribute.
if there is attribute, but no child i write from generic xml <odjeljak> with
same attribute to third xml, if there is child i do some processing and than
write it to third xml. if <odjeljak> from other xml doesnt have attribute i
write him to third xml.

what is the best approach to do that?

i have tried with XPath and XmlTextWriter
