un man vajag atlasīt pirmo urli ar type primary. kāds gudrāk prāts varētu man izpalidzēt kā to norealizēt?

[xPtv45z]

public function primary_url() {
foreach($this->data){
 if($type == 'primary'){
return $url;
 }
}
}

nu labi vinsh noker to type primary bet, ka zinās ka vajag tieshi to urli, kas ir virs viņa?

[indoom]

Varbūt kas šitāds

  $result = $xml_data->xpath("//wct_Seed[contains(wct_SeedType,'Primary')]");
  $data_row['url'] = !empty($result[0]) ? (string)$result[0]->wct_SeedURL : '';
  $data_row['type'] = 'Primary';

Kāpēc pirms, tu jau rakstīji - "man vajag atlasīt pirmo urli ar type primary"

 

Tev jau tur masīvā tiek salikti dati pa seediem, kam ir type un ir url parametri. Nav jau svarīgi vai xmlā, url atrodas pirms type vai pēc, kamēr viņi ir iekš viena seed.

Varbūt šis tev kaut kādu apgaismību dos, kā ko dabūt, no masīva - var_dump($this->data)

   	</wct:Seed>

bet tavs variants panem urli no secondary ša vai ta un tie type primary var but ari vairāki, tapēc vajag atlasit 1 ko atrod.

Parādi, ko izvada, $this->data, pēc loadXmlData izpildes.

[oskars21]

atrisināju savu sāpi ar, bet nu paldies par to pašu

 

if (count($xml_data->mets_dmdSec->mets_mdWrap->mets_xmlData->wct_wct->wct_Target->wct_Seeds->wct_Seed) > 0) {
  foreach ($xml_data->mets_dmdSec->mets_mdWrap->mets_xmlData->wct_wct->wct_Target->wct_Seeds->wct_Seed as $node) {

  if($node->wct_SeedType=='Primary')
$data_row['url']= $node->wct_SeedURL;

  }

[indoom]

Kāpēc xpath nederēja?
