Yini i-parsing ne-parser inentshisekelo kubantu abaningi. Ukuphathisa kufanele kuqondwe njengenqubo lapho kuhlaziywa khona umbhalo othile ngokubuka kwesilulumagama ne-syntax. I-Parser (i-syntactic analyzer) - ingxenye yohlelo olubhekele ukutadisha okuqukethwe ngemodi ezenzakalelayo nokuthola izingcezu ezidingekayo.
Kusetshenziselwani?
Ukuhlwaya kukuvumela ukuthi ucubungule inani elikhulu lolwazi ngesikhathi esifushane kakhulu. Lokhu kubhekisa ekuhlelweni okwenziwe ngokuhlelekile kwedatha ethunyelwe kumakhasi we-Intanethi. Ngakho-ke, ukuncozulula kusebenza kakhulu kunomsebenzi wezandla odinga isikhathi esiningi nomzamo.
Abahlinzeki banamakhono alandelayo:
- Ibuyekeza idatha, ikuvumela ukuthi ube nemininingwane yakamuva (amazinga wokushintshaniswa, izindaba, isibikezelo sezulu).
- Ukuqoqwa nokuphindwa ngokushesha kwezinto ezivela kwamanye amasayithi ukuze kuboniswe kuphrojekthi yakho ye-Intanethi. Izinto ezihluphayo zivame ukubhalwa kabusha.
- Ixhuma imifudlana yedatha. Inani elikhulu lolwazi litholwa lisuka kuzinsizakusebenza ezahlukahlukene, ezilula kakhulu lapho ugcwalisa amasayithi ezindaba.
- Ukubhangqa kusheshisa kakhulu umsebenzi ngamagama angukhiye noma amabinzana. Ngenxa yalokhu, kungenzeka ukukhetha ngokushesha izicelo ezidingekayo zokuphakanyiswa kwephrojekthi.
Izinhlobo ze-Parser
Ukuthola imininingwane kwi-Intanethi kuyinkambiso enzima kakhulu, ejwayelekile neyesikhathi eside. Abahlinzeki ngosuku olulodwa bayakwazi ukucubungula, ukuzenzekelayo nokuhlunga isabelo sengonyama semithombo yewebhu befuna imininingwane edingekayo.
Ukuhlwaya kukuvumela ukuthi ulawule ukwehluka kwama-athikili ngokufanisa ngokushesha nangokunembile okuqukethwe kwezinkulungwane zamakhasi we-Intanethi nombhalo onikeziwe.
Namuhla, ungalanda noma uthenge izinhlelo eziningi ezisebenzayo zokukhuhla, kufaka phakathi i-Ixt.io, iWebhose.io, iScrapinghub, iParseHub, iSpinn3r nezinye.
Uyini umhloli wesiza
Isikhombi sendawo senziwa ngokuya ngohlelo olufakiwe, ngokuqhathanisa inhlanganisela ethile yamagama nalokho okutholwe kuwebhu.
Ungasebenza kanjani ngolwazi olutholile kubhalwe kulayini womyalo obizwa nge- "expression ejwayelekile". Yakhiwa ngezimpawu futhi ihlela umgomo wokusesha.
Isihloli sesayithi sihamba ngezigaba eziningana:
- Isesha imininingwane edingekayo kunguqulo yoqobo: ukuthola ukufinyelela kwikhodi yesiza se-Intanethi, ukulanda, ukulanda.
- Ukuthola imisebenzi kusuka kwikhodi yekhasi lewebhu, ngokukhishwa kwento edingekayo kusuka kukhodi yohlelo yekhasi.
- Ukwenziwa kombiko ngokuya ngezidingo ezisunguliwe (ukurekhoda imininingwane ngqo kuzizinda zolwazi, izindatshana).
