XML kan Server

Fayil na XML yana da dabi'insa mai iya kewaye da fayil na HTML.

Za a iya amfani da serveran web naандартan don amfani da amfani da samun XML.

Rufe XML fayil a kan server

Hanyar da XML fayil ana amfani da ita a kan serveran Internet da HTML fayil.

Kai amfani da kofin kula na Windows, kuma shiri a cikin hakan:

<?xml version="1.0" encoding="UTF-8"?>
<note>
  <from>John</from>
  <to>George</to>
  <message>Remember me this weekend</message>
</note>

Kai kuma amfani da wani sunan fayil da yake, misali "note.xml", zama a kewaye fayil a kan serveri na web.

Samun XML a kan PHP

Za a samu XML a kan server, kuma ba'a buwa samun software na XML ba.

Domin da za a samu XML a kan server a kan PHP, za a yi amfani da kudaden hakan:

<?php
header("Content-type: text/xml");
echo "<?xml version='1.0' encoding='UTF-8'?>";
echo "<note>";
echo "<from>John</from>";
echo "<to>George</to>";
echo "<message>Remember me this weekend</message>";
echo "</note>";
?>

Raba, kudaden zagayen yadda zai cikin 'text/xml' an ba shi.

Gani wannan PHP file da ke samun daga server.

Kwam ka a hauka PHP, baca da nassanin da PHP da nassanin nasa.

Ake samun XML ta ASP

XML zai samu a server kuma ba'a dace ne a samun software XML.

Lakokan dake da ake haka kodo na XML samun daga server - kuma ake haka shi a server a matsayin ASP fi

<%
response.ContentType="text/xml"
response.Write("<?xml version='1.0' encoding='UTF-8'?>")
response.Write("<note>")
response.Write("<from>John</from>")
response.Write("<to>George</to>")
response.Write("<message>Remember me this weekend</message>")
response.Write("</note>")
%>

Raba, alama samun na yau ya kamata a kafa kuma ya zama "text/xml".

Gani wasan ASP kamar yake yake kammala daga server

Idan ka daceka a ƙa'idar ASP, ka akwai asaƙiyyar ASP na wa

Samun XML daga database

XML za a samu daga database, kuma ba'a dace ne a samun software XML.

Lakokan dake da ake kodo haka da kafa XML samun da kafa a mai shi kafa a server, kuma a kafa shi a ASP fi

<%
response.ContentType = "text/xml"
set conn=Server.CreateObject("ADODB.Connection")
conn.provider="Microsoft.Jet.OLEDB.4.0;"
conn.open server.mappath("/datafolder/database.mdb")
sql="select fname,lname from tblGuestBook"
set rs=Conn.Execute(sql)
response.write("<?xml version='1.0' encoding='UTF-8'?>")
response.write("<guestbook>")
while (not rs.EOF)
response.write("<guest>")
response.write("<fname>" & rs("fname") & "</fname>")
response.write("" & rs("lname") & "")
response.write("")
rs.MoveNext()
wend
rs.close()
conn.close()
response.write("")
%>

查看以上 ASP 代码的实际数据库输出

上面的例子使用了带有 ADO 的 ASP。

在服务器上使用 XSLT 来转换 XML

下面的 ASP 代码在服务器上把 XML 文件转换为 HTML：

<%
' 加载 XML
set xml = Server.CreateObject("Microsoft.XMLDOM")
xml.async = false
xml.load(Server.MapPath("simple.xml"))
' 加载 XSL
set xsl = Server.CreateObject("Microsoft.XMLDOM")
xsl.async = false
xsl.load(Server.MapPath("simple.xsl"))
' 转换文件
Response.Write(xml.transformNode(xsl))
%>

例子解释

  1. 第一个代码块创建微软 XML 解析器的实例 (XMLDOM)，并把 XML 文件载入内存
  2. 第二个代码块创建解析器的另一个实例，并把 XSL 文件载入内存
  3. 最后一行代码使用 XSL 文档转换 XML 文档，并将结果作为 HTML 发送到浏览器。完工！

看看上面的代码如何运行

通过 ASP 把 XML 保存为文件

这个 ASP 实例会创建一个简单的 XML 文档，并把该文档保存到服务器上：

<%
"<note>"
text=text & "<to>George</to>"
text=text & "<from>John</from>"
text=text & "<heading>Reminder</heading>"
text=text & "<body>Don't forget the meeting!</body>"
text=text & "</note>"
set xmlDoc=Server.CreateObject("Microsoft.XMLDOM")
xmlDoc.async="false"
xmlDoc.loadXML(text)
xmlDoc.Save("test.xml")
%>
