Uyini XML uvula futhi kanjani ukuyisebenzisa.

Lezi zinkinga nkinga ivame kakhulu phakathi yabasebenzisi ezithangamini ezehlukene anikezelwe izilimi izinhlelo web diayna. Ukuze uqale nge siyowuqonda, lokho xml format kuka ukuze uyivule ukuhlela.

Ngakho, i-XML siwulimi izinhlelo Olwandisekayo esikhethekile sakhiwo. Ngakho-ke, amafayela we-XML usebenzisa tags ukuthi ichaze izimfanelo lezinto. Ngokubukeka, ulimi kakhulu efana ulimi evamile izinhlelo HTML. Nokho, i-XML Umehluko amandla wabasebenzisi ukusetha tags zabo futhi uwasebenzise esikhathini esizayo.

Ngo oyiyo, idokhumenti ye-XML kungumuthi izakhi. Ezinye izici eziningana ezinjengolwazi kunjalo nge-HTML banezidingo izimfanelo yabo enwetshiwe, futhi ingaqukatha iyiphi amagugu. Ngokwesibonelo emgqeni: Inani, kukhona tags sidabukile kanye lokuvala yonkana umugqa. Inani ATTR yisibaluli, kodwa attrval - lena ukubaluleka imfanelo ngenhla. Nokho, kungxenye yokugcina yenani bentsambo okuqukethwe.

Okwamanje, ifayela le-XML ziye kabanzi futhi ezidume phakathi kwabasebenzisi. Ngaphezu kwalokho, nezimo of ulimi lokwakha izinhlelo ikuvumela ukuthi usebenzise amafayela ezifana izinhlelo zokusebenza ukwenza izilungiselelo ezahlukene kanye nokudala yolwazi ehlukene. Nakuba inhloso yokuqala ulimi yomdwebo kuyinto ukuyisebenzisa ifayela ngokwabelana ngolwazi phakathi izinhlelo kwi-World Wide Web.

Ngakho, xml format kuka ukuze uyivule futhi kanjani uyihlele. Indlela elula ukukwenza - ukuvula ifayela le-XML ne sombhalo efana amafayela HTML. Nokho, ukuhlela Amafayela e-XML lokhu format kudinga ubungoti umsebenzisi nolwazi zokusebenza ze-XML ulimi yomdwebo. Okusho ukuthi, lapho uvula ifayela e incwajana ekhasini lakho, uthola iqoqo imigqa yekhodi saphinde yomdwebo umbhalo ngokwawo. Futhi udinga ukuhlela ke kancane ukuqonda ukubalekela imithwalo yemfanelo yokuba ithegi othize, futhi lapho udinga ukwenza ukuhlela lokho ulwazi ufuna ukubonisa kahle.

Labo abazi-XML ulimi noma ufuna ngokushesha ubone umphumela uma uhlela ingakwazi izinhlelo ezikhethekile ezikuvumela ukuvula amafayela nge extension XML. Ngakho-ke, ngenxa engaqaliwe kulezi zindaba xml format ulivula, izinhlelo ezinjalo kuyoba insindiso yangempela. Phakathi abahleli eziningi ezinjalo, lapho mabi kakhulu nezobuchwepheshe, kanye uhlelo elula kubasebenzisi imfundamakhwela. Nakuba izimiso ka bahlela nokudala Amafayela e-XML kubo zifana. Zonke izinhlelo kuhluke kuphela ukusebenza yabo, kanye iqoqo imisebenzi namathuluzi wokuhlela nokudala amafayela we-XML.

Phakathi izinhlelo elula khulula ukuvula ifayela le-XML futhi ihlelwe kahle ngokwengeziwe noma ukudala ngokuphelele amafayela amasha ungabahlukanisa umhleli SERNA Mahhala yomthombo ovulekile. Kuyinto enamandla kodwa ngesikhathi esifanayo elula futhi okulula isofthiwe evumela ukuthi wena kalula ukudala izihloko kanye nezincwadi, ezihlukahlukene imibhalo yokusebenza, umsebenzisi nokunye okuningi. Ngaphezu kwalokho, ukusebenza phezu kwendalo kanye ukuhlela in the umhleli-XML bebutha kakhulu umsebenzi sombhalo elula njengoba iZwi nokunye, nokunye akudingi ulwazi abalulekile-XML ulimi yomdwebo. Ngakho-ke, usebenzisa le nezindaba software efana kanjani ukuze usebenze ngamafayela kokuba xml format ulivula ngeke usakwazi kuphakama.

izici engeziwe SERNA Mahhala Umhleli ugqamise khona Olwandisekayo-FO Olwandisekayo kanye XSLT, esinikela isibonisi enengqondo kakhulu ngezinto ezinyathelisiwe, futhi likuvumela ukudala ukubukwa futhi profiled integrally kumephu amafayela we-XML, yakhiwa inqwaba izingxenye.
