Question

我使用此代码从DataTable导出到XML文件：

dt1 = TNET2_POHeadService.TNET2_POHead_GetByPO_NoRaw(PO_No);
                dt2 = TNET2_PODetailsService.TNET2_PODetails_GetByPO_NoRaw(PO_No);
                ds.Tables.Add(dt1);
                ds.Tables[0].TableName = "TNET2_POHead";
                ds.Tables.Add(dt2);
                ds.Tables[1].TableName = "TNET2_PODetails";
                saveFileDialog1.ShowDialog();

                ds.WriteXml(saveFileDialog1.FileName);

一切正常但是：

<ContractNo>P1717-198905-003(01)</ContractNo>
<KP_No xml:space="preserve">             </KP_No>
<SettlementRoute1>TENTAC SUZHOU</SettlementRoute1>

KP_No标记为空白值。我想删除xml：space =＆＃34;保留＆＃34; XML导出文件。怎么做？

<?php $successful_students_items = get_post_meta( get_the_id(), 'successful_students_block_box', true ); if( !empty( $successful_students_items ) ) { foreach( $successful_students_items as $successful_students_item ) { ?> <div class="ipd-je-8 ipd-rz-8 ipd-pv-12 ipd-ke-24"> <div class="rjeudirnskxzi nnu"> <div class="h1ge6swchqzj6de"> <div class="h1ge6swchqzj6de_cvz"> <figure class="o309iruhgtybgyu5"> <blockquote><?php echo $successful_students_item['successful_students_block_testimonial']; ?> <div class="ingi3h38d8jj4"></div> </blockquote> <img alt="" src="<?php echo $successful_students_item['successful_students_block_image']; ?>"/> <div class="ewr4i9548jfdeuthie"> <h5><?php echo $successful_students_item['successful_students_block_name_lastname']; ?> <span> <br> <?php echo $successful_students_item['successful_students_block_position']; ?> </span> </h5> </div> </figure> </div> </div> </div> </div> <?php } } ?>命名空间中的 XDocument 类允许使用LINQ轻松管理和操作XML。

请参阅下面的示例，从XML文件的 KP_No 元素中删除System.Xml.Linq属性：

xml:space="preserve"

请注意，您的XML没有根元素。在XML中定义一个是一个好习惯。

上面的代码段后面的结果：

XDocument doc = XDocument.Load("XMLFile1.xml"); // or XDocument.Load(myStream) ...

Func<XAttribute, bool> preserveAttrFunc = atr => atr.Name.LocalName == "space" && atr.Value == "preserve";
XElement kp_no = doc.Descendants("KP_No").FirstOrDefault(kp => kp.HasAttributes && kp.Attributes().Any(preserveAttrFunc));

if(kp_no != null)
    kp_no.Attributes().FirstOrDefault(preserveAttrFunc).Remove();

// doc.Save(filename) ...

删除xml：space =＆＃34;保留＆＃34;使用C＃的XML文件
