XSLT - Tafinfin XML

Data na sabuntawon dominan file na XML zaii yanbian dominan browser na internet.

Ba, yanbian da sabuntawon, da sabuntawon XML

Bayan, akan jini koyan dominan ba, yanbian da sabuntawon dominan server na XML file.

Akan jini dominan XSL dominan XML document dominan HTML form. Value na XML element zaii wuro dominan HTML input domain. Form na zaii yanzu. Bayan na zaii yanbian, data zaii sabuntawon dominan server, file na XML zaii yinshen (na part dominan ASP).

Fiilen XML da fiilen XSL

Kafin, kai koye kan fiilen XML da za a yi amfani da su ("tool.xml"):

<?xml version="1.0" encoding="ISO-8859-1"?>
<tool>
  <field id="prodName">
    <value>HAMMER HG2606</value> 
  </field>
  <field id="prodNo">
    <value>32456240</value> 
  </field>
  <field id="price">
    <value>$30.00</value> 
  </field>
</tool>

Kai koye XML fiilen.

Sannan, kai koye kan kusan furenwa ("tool.xsl"):

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
<xsl:template match="/">
<html>
<body>
<form method="post" action="edittool.asp">
<h2>Information kan Tarihi (tafiya):</h2>
<table border="0">
<xsl:for-each select="tool/field">
<tr>
<td>
<xsl:value-of select="@id"/>
</td>
<td>
<input type="text">

<input type="submit" id="btn_sub" name="btn_sub" value="Submit" />
<input type="reset" id="btn_res" name="btn_res" value="Reset" />

Gani fayilin XSL.

Wannan XSL fiilen zai kaiyakiya abubu XML fiilen furenwa, kuma yana a furo akwai "field" furenwa dake. Id atawu "field" furenwa a yana kama akwai gurɗe id da name na kowane HTML input furenwa. "value" furenwa a yana kama akwai gurɗe "value" na kowane HTML input furenwa. Nema, za a samu form HTML da ake gudanarwa da kowane wuri a cikin XML fiilen.

Sannan, a kuma da shaidin sabuwar sabon: "tool_updated.xsl". Fayilin XSL na yau za'a amfani domin nuna bayanin XML na an samar da. Sabon XSL na yau zai zartar da fariyanci HTML wanda ke iya yin abubuwa, wanda zai zartar da taba HTML:

<?xml version="1.0" encoding="ISO-8859-1"?>

Fayilin ASP

A cikin fayilin "tool.xsl" yau, matsaka HTML fariyanci action na jumla ce "edittool.asp" .

"edittool.asp" bayanin tace dambobin: loadFile() ya'a wanda ke cikawa da wucewa XML bayanin, updateFile() ya'a samar da bayanin XML:

<%
function loadFile(xmlfile,xslfile)
Dim xmlDoc,xslDoc
ya kama fiyi XML
