如何在WPF VB中向XML文件添加新的子集条目？ [英] How do I add a new subset entry to an XML file in WPF VB?

问题描述

我有一个XAML文档，其中包含多个客户名称和联系人数据的文本框（即地址，电话，传真，联系人姓名，电子邮件地址）。我有一个sub来检查绑定的xml文档，看看客户名是否已经存在，如果没有，它会为所有文本框创建一个新条目。至少这是个主意。我知道必须有一种方法可以一举将所有XMLElements附加到源代码，但我似乎无法弄清楚如何简化此事件。我想要包括所有缩进和XML验证。



XML数据就这样形成......

 <？  xml    < span class =code-summarycomment> version   =  1.0   编码  =  utf-8 ？ >  
 <   CustDB     xmlns ：xsi   =  http://www.w3.org/2001/XMLSchema-instance >  
 <  客户 >  
 <  名称 >  <   / Name  >  
 <  地址1  >   <   / Address1  >  
 <  地址2  >  < ;   / Address2  >  
 <  电话 >  <   / Phone  >  
 <  传真 >  <   / Fax  >  
 <  单元格 >  <   / Cell  >  
 <  其他 >  < span class =code-keyword><   / Other  >  
 <   Attn  &g t;  <   / Attn  >  
 <  电子邮件 > ;  <   / Email  >  
 <   SalesPerson  >  <   / SalesPerson  >  
 <   / Customer  >  
 <   / CustDB   >  

解决方案

你好，



L inq to XML。

VB.Net代码为：< br $> b $ b

 Dim custDB = _ 
 <   CustDB  >  
 <   / CustDB  >  
 
 Dim customer = _ 
 <  客户 >  
 <  名称 >  Mr test <   / Name  >  
 <   Address1  > 添加1 <   / Address1  >  
 <  地址2  > 添加2 <   / Address2  >  
 <  电话 >  <   /电话 >  
 <  传真 >  < ;   / Fax  >  
 <   Cell  >  <   / Cell  >  
  <  其他 >  <   /其他 >  
 < ;   Attn  >  <   / Attn  >  
 <  电子邮件 >  <   /电子邮件 >  
 <   SalesPerson  >  <   / SalesPerson  >  
 <   /客户 >  
 
 custDB.Add（客户）

就这么简单。

I have an XAML doc that has several textboxes for customer name and contact data (i.e. address, phone, fax, contact name, email address). I have a sub that checks the bound xml document to see if the customer name already exists and if not it creates a new entry for all the text boxes. At least that's the idea. I know there has got to be a way to append all the XMLElements to the source in one fell swoop, but I can't seem to figure out how to streamline this event. I want to include all indenting and XML validation as well.

XML data is formated as such...

<?xml version="1.0" encoding="utf-8"?>
<CustDB xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <Customer>
    <Name></Name>
    <Address1></Address1>
    <Address2></Address2>
    <Phone></Phone>
    <Fax></Fax>
    <Cell></Cell>
    <Other></Other>
    <Attn></Attn>
    <Email></Email>
    <SalesPerson></SalesPerson>
  </Customer>
</CustDB>

hello,

Linq to XML.

The VB.Net code is:

Dim custDB = _
    <CustDB>
    </CustDB>

Dim customer = _
  <Customer>
    <Name>Mr test</Name>
    <Address1>Add 1</Address1>
    <Address2>add 2</Address2>
    <Phone></Phone>
    <Fax></Fax>
    <Cell></Cell>
    <Other></Other>
    <Attn></Attn>
    <Email></Email>
    <SalesPerson></SalesPerson>
</Customer>

custDB.Add(customer)

it's that simple.
