Xml has been used in recent projects. You need to save a series of data to the xml file before installing the product, and write the data to the database only after the last step is executed, this minimizes database access, so you have to struggle with the compatibility of various browsers (sad ....)
The following is an xml file (createInstal. xml)
<? Xml version = "1.0" encoding = "UTF-8"?>
<Info>
<Item>
<Id descrption = "level" name = "1" f_chines = "no." t_chines = "commandid" english = "id" value = "1"> NO. </id>
<Levelname descrption = "" name = "" f_chines = "" t_chines = "" english = "Level-Name" value = "Level 1"> Level name </levelname>
<Decrption descrption = "Level" name = "" f_chines = "Level Description" t_chines = "Level Description" english = "Level-Description" value = "Level Description 1"> Description </decrption>
<Tchines descrption = "level" name = "" f_chines = "Traditional Chinese" t_chines = "Traditional Chinese" english = "T-Chinese" value = "Others"> traditional Chinese chinese </Tchines>
<English descrption = "level" name = "" f_chines = "english name" t_chines = "English name" english name = "english" value = "LevelOne"> english name </English>
<Award 6 descrption = "Award" name = "106" f_chines = "award 6" t_chines = "000000006" english = "Worda-of-t" value = "" />
<Award 11 descrption = "Award" name = "111" f_chines = "award 11" t_chines = "201710000000011" english = "11" value = "0.05"/>
<Award 12 descrption = "Award" name = "112" f_chines = "Award 12" t_chines = "0000000012" english = "2222" value = "0.04"/>
<Award 13 descrption = "Award" name = "113" f_chines = "award 13" t_chines = "0000000013" english = "3333" value = "0.85"/>
<Award 1 descrption = "Award" name = "101" f_chines = "award 1" t_chines = "Copyright Anyi" english = "Aword-of-a" value = "0.90" />
</Item>

To be compatible with IE and FF, write the following functions (loadxml. js ):
Var is_Ie = false; // whether the browser is an IE browser
If (window. ActiveXObject ){
Is_Ie = true;
}
// Load xml documents compatible with multiple browsers
Function loadXml (xmlUrl ){
Var xmldoc = null;
Try {
Xmldoc = new ActiveXObject ("Microsoft. XMLDOM ");
}
Catch (e ){
Try {
Xmldoc = document. implementation. createDocument ("", "", null );
} Catch (e ){
Alert (e. message );
}
}
Try {
// Disable asynchronous loading
Xmldoc. async = false;
Xmldoc. load (xmlUrl );
Return xmldoc;
}
Catch (e ){
Alert (e. message );
}
Returnnull;
}
// Replace a string in xml document format with an xml document
Function createXml (xmlText ){
If (! XmlText ){
Returnnull;
Try {
Var xmldocm = new ActiveXObject ("Microsoft. XMLDOM ");
Xmldocm. loadXML (xmlText );
Return xmldocm;
}
Catch (e ){
Try {
Returnnew DOMParse (). parseFromString (xmlText, "text/xml ");
}
Catch (e ){
Returnnull;
}
}
}
}
// Obtain the text of the node and Its subnodes
Function getXmlText (oNode ){
If (oNode. text) {// IE
Return oNode. tex;
}
Var sText = "";
For (var I = 0; I <oNode. childNodes. length; I ++) {// traverse subnodes
If (oNode. childNodes [I]. hasChildNodes () {// whether a subnode exists
SText + = getXmlText (oNode. childNodes [I]);
} Else {
SText + = oNode [I]. childNodes. nodeValue;
}
}
Return sText;
}
// Obtain the string ID of the node and Its subnodes
Function getXml (oNode ){
If (oNode. xml) {// IE
Return oNode. xml;
}
Var serializer = new XMLSerializer ();
Return serializer. serializeToString (oNode );
}
// Obtain the text of the specified Node
Function getxmlnodeText (oNode ){
If (is_Ie ){
Return oNode. text;
} Else {
If (oNode. nodeType = 1)
Return oNode. textContent;
}
}
// Obtain the attribute value of the specified Node
Function getxmlnodeattribute (oNode, attrName ){
If (is_Ie ){
Return oNode. getAttribute (attrName );
} Else {
If (oNode. nodeType = 1 | oNode. nodeType = "1 ")
Return oNode. attributes [attrName]. value;
Return "undefined ";
}
}
OK IE and FF are no longer problems. The specific operation method is as follows:
Var docum = loadxml ("createInstal. xml"); // load an xml file
Var root = cmd.doc umentElement; // root Node
Var nodelist = root. getElementsByTagName ("Items ");
For (var I = 0; I <nodelist [0]. childNodes. length; I ++)
{
Var attr = getxmlnodeattribute (nodeList [0]. childNodes [I], "descrption"); // obtain the descrption attribute of this node
If (attr! = "Undefined") // The objective is to be compatible with the FF Browser
{
Alert (attr );
}
}
This ensures the compatibility between IE and FF (Google's browser is currently unable to use this method for compatibility and is still to be modified)
