XML er et verktøy for deling av strukturerte data mellom informasjonssystemer, særlig over internett. XML brukes imidlertid også til koding av dokumenter og som kommunikasjonsmiddel mellom ulike informasjonssystemer og dataformater. Filformatet .xml organiserer data i en hierarkisk struktur. Formatet er et vanlig tekstformat, leselig for mennesker, der <i>merker</i>, eller <i>tagger</i>, gir informasjon om hva innholdet er.<sup id="cite_ref-XmlOriginsGoals_1-0" class="reference"><a href="#cite_note-XmlOriginsGoals-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>Spesifikasjonen av XML, som gis ut av <a href="/wiki/World_Wide_Web_Consortium" title="World Wide Web Consortium">W3C</a>, fastsetter et metaspråk som andre språk kan defineres ut fra.

For at et dokument skal regnes for å være «velformet» (<a rel="nofollow" class="external text" href="http://www.w3.org/TR/REC-xml#sec-well-formed">W3C Recommendation XML 1.0 (Third Edition)</a>), må det som minimum oppfylle følgende: </p> <ul><li>Det må ha ett og bare ett rotelement.</li> <li>Ikke-tomme elementer må begrenses av en starttagg og en sluttagg med samme navn: <code><avsnitt>...</avsnitt></code>.

Det betyr at alle ikke-rotelementer må være fullstendig inneholdt i et annet element.</li> <li>Det er forskjell på store og små bokstaver i elementnavn.

Dette krevde videre utvikling av spesiell lese- og skrivekode samt detaljerte formatbeskrivelser. </p><p>XMLs regelmessige struktur og strenge syntaksregler gjør at programvareutviklere kan bruke standard kode for lesing og skriving.

XSD har langt sterkere uttrykksevne enn DTD til å beskrive XML-språk. Dessuten bruker XSD et XML-basert format som gjør det mulig å anvende XML-verktøy til å prosessere XSD-dokumenter.

RELAX NG har to hovedretninger for syntaksen, en som er XML-basert og en kompakt variant som ikke bruker XML. Den kompakte syntaksen sikter mot å øke lesbarhet og skrivbarhet, mens siden det finnes en veldefinert måte å oversette kompakt syntaks til XML-syntaks og tilbake igjen, har en ikke mistet fordelen med å kunne bruke standard XML-verktøy. RELAX NG har en mer kompakt definisjon, noe som gjør den lettere å implementere enn XSD. </p><p>Noen skjemaspråk beskriver ikke bare strukturen til et gitt XML-format, men tilbyr også noen enkle muligheter for å prosessere individuelle XML-filer som følger formatet. Både DTD og XSD har denne evnen. De kan for eksempel forsyne XML-dokumenter med default-verdier. I RELAX NG har en bevisst unnlatt å tilby slike egenskaper. </p> <div class="mw-heading mw-heading2"><h2 id="Visning_av_XML_på_Internett"><span id="Visning_av_XML_p.C3.A5_Internett"></span>Visning av XML på Internett</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=XML&veaction=edit&section=4" title="Rediger avsnitt: Visning av XML på Internett" class="mw-editsection-visualeditor"><span>rediger</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=XML&action=edit&section=4" title="Rediger kildekoden til seksjonen Visning av XML på Internett"><span>rediger kilde</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><a href="/wiki/Extensible_stylesheet_language" class="mw-redirect" title="Extensible stylesheet language">Extensible stylesheet language</a> (XSL) er et tillegg til XML som gjør det mulig å beskrive visuelle egenskaper og transformasjoner av XML-data uten å legge instruksjonene inn i dataene selv.

XPath kan navigere gjennom disse nodene og bruke logiske operatorer og funksjoner på dataene som ligger i dokumentet. </p><p><a href="/wiki/XQuery" title="XQuery">XQuery</a> er et <a href="/wiki/Sp%C3%B8rrespr%C3%A5k" title="Spørrespråk">spørrespråk</a> som brukes på XML-data. XQuery kan brukes til kommunikasjon mellom nett og databaser og er sammen med XML et skritt i retning av det semantiske nett, som er en av visjonene til W3C. Tanken er at informasjon i XML-dokumenter i større grad merkes med innhold, slik at det er lettere for informasjonssystemer å søke opp og sammenligne aktuell informasjon. </p><p><br /> </p> <div class="mw-heading mw-heading2"><h2 id="Prosessering_av_XML-filer">Prosessering av XML-filer</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=XML&veaction=edit&section=6" title="Rediger avsnitt: Prosessering av XML-filer" class="mw-editsection-visualeditor"><span>rediger</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=XML&action=edit&section=6" title="Rediger kildekoden til seksjonen Prosessering av XML-filer"><span>rediger kilde</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>API-ene (Application Program Interface) mest brukt for prosessering av XML-data via et programmeringsspråk er <a href="/w/index.php?title=Simple_API_for_XML&action=edit&redlink=1" class="new" title="Simple API for XML (ikke skrevet ennå)">SAX</a> og <a href="/w/index.php?title=DOM_(XML_API)&action=edit&redlink=1" class="new" title="DOM (XML API) (ikke skrevet ennå)">DOM</a>.

Spesifikasjonen til den første versjonen, XML 1.0, er nå revidert for tredje gang. </p><p>XML 1.0 og XML 1.1 er ulike i forhold til krav til tegn som kan brukes i elementnavn, attributtnavn o.l.: XML 1.0 tillater bare tegn som er lovlige <a href="/wiki/Unicode" title="Unicode">Unicode</a> 2.0. Dette inkluderer de fleste «world scripts», men utelukker «scripts» som kan brukes i senere versjoner av Unicode, som <a href="/wiki/Mongolsk" title="Mongolsk">mongolsk</a>, <a href="/w/index.php?title=Kambodsjansk&action=edit&redlink=1" class="new" title="Kambodsjansk (ikke skrevet ennå)">kambodsjansk</a>, <a href="/wiki/Amharisk" title="Amharisk">amharisk</a>, <a href="/wiki/Burmesisk" title="Burmesisk">burmesisk</a>, etc. XML 1.1 har begrensninger bare når det gjelder visse <a href="/w/index.php?title=Styretegn&action=edit&redlink=1" class="new" title="Styretegn (ikke skrevet ennå)">styretegn</a>, hvilket innebærer at alle andre tegn kan brukes, selv om Unicode-standarden vokser eksponensielt. </p><p>Det bør nevnes at begrensningen som er til stede i XML 1.0 bare gjelder element- og attributtnavn (komponentnavn). Både XML 1.0 og XML 1.1 tillater alle Unicode-tegn i selve innholdet. XML 1.1 er derfor bare nødvendig dersom du ønsker å bruke Unicode i komponentnavn. </p><p>Andre mindre endringer mellom XML 1.0 og XML 1.1 er at <a href="/w/index.php?title=Styretegn&action=edit&redlink=1" class="new" title="Styretegn (ikke skrevet ennå)">styretegn</a> nå tillates bare om de inngår i en escape-sekvens. To spesielle formfeed-tegn, som må behandles som «whitespace», er inkludert. </p><p>Alle XML 1.0-dokumenter er lovlige XML 1.1-dokumenter, med ett unntak: XML-dokumenter som erklærer seg selv som <a href="/wiki/ISO_8859-1" title="ISO 8859-1">ISO-8859-1</a>-kodet, som betyr <a href="/w/index.php?title=CP1252&action=edit&redlink=1" class="new" title="CP1252 (ikke skrevet ennå)">CP1252</a>-kodet, kan nå være ulovlig. Dette er fordi CP1252 bruker styretegnblokker av ISO-8859-1 for spesielle tegn, som €, Œ, og ™. XML 1.0-dokumenter som deklarerer CP1252-koding vil likevel være gyldige. </p><p>Det snakkes også om XML 2.0, selv om det gjenstår å se om det noensinne dukker opp. XML-SW (SW for <a
