How to Use jquery to add, delete, modify, and delete xml files

You can clearly describe the problem.

Is the XML data on the Web page operated?
Is it an operation on the passed XML data?
Is the XML file on the local hard disk operated?

Provide the following ideas:

You can use jquery's $. ajax () to request the xml resource. In this way, the parameter dataType: xml can be traversed on the local js Code. Display the file on the page. After modification and deletion, the data is transmitted to the background in JSON format for file read and write operations.
$. Ajax ({
Url: rootPath + "/userInfo. do? Method = saveSetting & columnIds =... ",
DataType: "json ",
Success: function (response ){
If (response ){

Alert ("saved successfully ");
}
Else
Alert ("failed to save ");
}
}
});

1. Read xml files/Content 1. Read xml files $. get (xmlfile. xml, function (xml) {// xml is the content that can be read and used. For details, see 2nd }); 2. Read xml content. If the read xml is used for the xml file, the above points are used to process the following $. get (xmlfile. xml, function (xml) {$ (xml ). fi
I. Reading xml files/Content
1. Read xml files
$. Get ("xmlfile. xml", function (xml ){
// Xml indicates the content that can be read and used. For details, refer to 2nd.
});
2. Read xml content
If the read xml is used for the xml file, the processing is as follows in combination with the above point:
$. Get ("xmlfile. xml", function (xml ){
$ (Xml). find ("item"). length;
});
If you read an xml string, note that the xml string must be surrounded by "<xml>" and "</xml>" before it can be parsed.
$ ("<Xml> <root> <item> </root> </xml> "). find ("item "). length; II. Example xml for parsing xml content: <? Xml version = "1.0" encoding = "UTF-8"?> <Fields>
<Field Name = "Name1">
<Fieldname> dsname </fieldname>
<Datatype> character </datatype>
</Field>
<Field Name = "Name2">
<Fieldname> dstype </fieldname>
<Datatype> character </datatype & ...... remaining full text>

JQUERY parses XML and returns html

Var xml = "the xml string"; var table = $ ("the table selector"); $ (xml ). find ("viewentry "). each (function () {var tr = $ ("<tr>"); $ (this ). find ("entrydata "). each (function () {tr. append ("<td>" + $ (this ). child ("text "). text + "</td>") ;}); table. append (tr) ;}); I have never tested it, but it is probably like this.
