如何用XML编码?

问题描述

早上好，我有一个asp.net Web应用程序，我正在从某个外部soft.flash生成一个Fix images的Flash文档.随着那个XML文件的生成，请参见xml代码

Good Morning to all I have an asp.net web application I am generating a flash document of Fix images from some external soft.with that a XML file is generating plz see xml code

<?xml version="1.0" encoding="UTF-8" ?>
<flash_parameters>
  <preferences>
    <golbal>
      <basic_property html_title="Title" loadStyle="Bar" hideAdobeMenu="false" photoDynamicShow="true" enableURL="true" startAutoPlay="true"/>
      <music_property path="" stream="true" loop="true"/>
      <description_property enable="true" backgroundColor="0xc0c0c0" backgroundAlpha="10" cssText="a:link{text-decoration: underline;} a:hover{color:#ff0000; text-decoration: none;} text-decoration: underline;} .body{color:#ff5500;font-size:20px;}" align="bottom"/>
      <background_property backgroundColor="0x000000" backgroundImage="res/bg-0162.gif" mode="tile"/>
    </golbal>
    <thumbnail>
      <basic_property thumWidth="100" thumHeight="80" thumbnailborderColor="0xfffbf0" currentbordercolor="0x000000" thumborder="5" thumSpacing="8"/>
      <button_property enablebutton="true" buttoncolor="0xfffbf0"/>
    </thumbnail>
  </preferences>
  <album>
    <slide jpegURL="thumbs/t_0009.jpg" d_URL="slides/p_0009.jpg" transition="0" panzoom="1" URLTarget="0" phototime="2" url="" title="DSCF1810" width="800" height="600"/>
    <slide jpegURL="thumbs/t_0010.jpg" d_URL="slides/p_0010.jpg" transition="0" panzoom="1" URLTarget="0" phototime="2" url="" title="DSCF1813" width="800" height="600"/>
      </album>
</flash_parameters>

现在，假设我想在专辑"部分下添加额外的图像，以便我如何通过编程在XML中添加额外的图像代码.

Now suppose i want to add extra image under "album" part so how i add extra image code in XML through programming.

推荐答案

Private Sub InsertImage(ByVal jpegURL As String, _
                            ByVal dURL As String, _
                            ByVal title As String, _
                            ByVal width As Integer, _
                            ByVal height As Integer)

    Dim doc As New XmlDocument
    Dim filePath As String
    filePath = "xml file path"

    doc.Load(filePath)

    Dim root As XmlNode = doc.DocumentElement

    Dim nav As Xml.XPath.XPathNavigator = doc.CreateNavigator

    nav = nav.SelectSingleNode("/flash_parameters/album")  '' Select the album element

    nav.AppendChildElement("", "slide", "", "")  '' add the slide element into album

    nav = nav.SelectSingleNode("/flash_parameters/album/slide[last()]")   '' select the last inserted slide element

    '' add attributes to the selected/last inserted slide element
    nav.CreateAttribute("", "jpegURL", "", jpegURL)
    nav.CreateAttribute("", "d_URL", "", dURL)
    nav.CreateAttribute("", "transition", "", "0")
    nav.CreateAttribute("", "panzoom", "", "1")
    nav.CreateAttribute("", "URLTarget", "", "0")
    nav.CreateAttribute("", "phototime", "", "2")
    nav.CreateAttribute("", "url", "", "")
    nav.CreateAttribute("", "title", "", title)
    nav.CreateAttribute("", "width", "", width)
    nav.CreateAttribute("", "height", "", height)

    doc.Save(filePath)   '' save the xml file
End Sub

XDocument xDoc = XDocument.Load(filePath);
            XElement albumElem = xDoc.XPathSelectElement("//slide[position()=last()]");

            albumElem.AddAfterSelf(new XElement("slide",
                new XAttribute("jpegURL", "some value"),
                new XAttribute("d_URL", "some value"),
                new XAttribute("transition", 0),
                new XAttribute("panzoom", 2)));  //Add more attributes as per your need.

            xDoc.Save(filePath);

如您所见，代码简明易懂.希望对您有所帮助.

As you can see the code is concise and readable. Hope it helped.
