JavaScript来动态添加CDATA节？ [英] Javascript to add cdata section on the fly?

问题描述

我在使用中存在的XML节点属性的特殊字符的麻烦。为了解决这个问题，我想呈现的属性子节点，并在必要时使用CDATA节来解决的特殊字符。问题是，我似乎无法得到追加到正确的节点CDATA部分。

我遍历源XML节点的属性和创建新的节点。如果attribute.name =说明我要把attribute.text（）在CDATA部分并追加新的节点。这就是我跳的轨道。

  // newXMLData是，我已经在内存中创建新的XML文档
    对于（VAR CTR = 0;＆CTR LT; this.attributes.length; CTR ++）{//遍历属性
          如果（this.attributes [CTR]。名称==说明）{//如果属性名称是说明添加CDATA节
             VAR thisNodeName = this.attributes [CTR]。名称;
               newXMLDataNode.append（＆下;+ thisNodeName +＆GT;＆下; /+ thisNodeName +＆gt;中）;
               VAR CDATA = newXMLData.createCDATASection（'测试'）; //这里的地方它打破。
          }其他{
           //这不是描述所以只需追加新的节点。
            newXMLDataNode.append（＆LT;+ this.attributes [点击率]。名称+＆gt;中。+ $（this.attributes [CTR]）文本（）+＆LT; /+ this.attributes [点击率。名+＆gt;中）;
          }
        }
 

任何想法？是否有另一种方式来增加CDATA节？

解决方案

我有同样的问题。我试图追加到CDATA XML节点，所以我想它的那么容易，因为添加像这样：

  valueNode [0]的.text =＆LT;！[CDATA [+ tmpVal +]]＆gt;中;
// valueNode [0]再presents＆LT; VALUE＆GT;＆LT; /值＆gt;中
 

这不起作用，因为整个事情会得到PTED为因此文字＆lt间$ P $（小于）和>（比大）会被自动替换

。

您需要做的是利用createCDATASection通过执行以下操作：

  VAR tmpCdata = $ xmlDoc中，[0] .createCDATASection（逃生（木子测试002））;
//我也转义特殊charactures以及
valueNode [0] .appendChild（tmpCdata）;
 

结果将是：

 ＆LT; VALUE＆GT;＆LT;！[CDATA [木子％20test％20002]＆GT;＆LT; /值＆GT;
 

Brettz9（以previous答案）解释如何做到这一点，但比较复杂，所以我只是想补充我的解决方案，它要简单得多。

感谢，

I'm having trouble with special characters that exist in an xml node attribute. To combat this, I'm trying to render the attributes as child nodes and, where necessary, using cdata sections to get around the special characters. The problem is, I can't seem to get the cdata section appended to the node correctly.

I'm iterating over the source xml node's attributes and creating new nodes. If the attribute.name = "description" I want to put the attribute.text() in a cdata section and append the new node. That's where I jump the track.

     // newXMLData is the new xml document that I've created in memory
    for (var ctr =0;ctr< this.attributes.length;ctr++){  // iterate over the attributes 
          if( this.attributes[ctr].name =="Description"){   // if the attribute name is "Description" add a CDATA section 
             var thisNodeName =  this.attributes[ctr].name;
               newXMLDataNode.append("<"+thisNodeName +"></"+ thisNodeName +">" );
               var cdata = newXMLData.createCDATASection('test');  // here's where it breaks. 
          } else {
           // It's not "Description" so just append the new node.
            newXMLDataNode.append("<"+ this.attributes[ctr].name +">" + $(this.attributes[ctr]).text() + "</"+ this.attributes[ctr].name +">"   );  
          }        
        } 

Any ideas? Is there another way to add a cdata section?

Here's a sample snippet of the source...

<row 
pSiteID="4" 
pSiteTile="Test Site Name " 
pSiteURL="http://www.cnn.com"
ID="1" 
Description="<div>blah blah blah since June 2007.&amp;nbsp; T<br>&amp;nbsp;<br>blah blah blah blah&amp;nbsp; </div>" 
CreatedDate="2010-09-20 14:46:18" 
Comments="Comments example.&#10;" >

here's what I'm trying to create...

<Site>
<PSITEID>4</PSITEID>
<PSITETILE>Test Site Name</PSITETILE>
<PSITEURL>http://www.cnn.com</PSITEURL>
<ID>1</ID>
<DESCRIPTION><![CDATA[<div>blah blah blah since June 2007.&amp;nbsp; T<br>&amp;nbsp;<br>blah blah blah blah&amp;nbsp; </div ]]></DESCRIPTION>
<CREATEDDATE>2010-09-20 14:46:18</CREATEDDATE>
<COMMENTS><![CDATA[ Comments example.&#10;]]></COMMENTS>
</Site>

解决方案

I had the same issue. i was trying to append CDATA to xml nodes, so i thought its as easy as adding like so:

valueNode[0].text = "<![CDATA["+ tmpVal +"]]>";
//valueNode[0] represents "<value></value>"

This does not work because the whole thing will get interpreted as text therefore <(less than) and > (great than) will be replaced automatically.

what you need to do is use createCDATASection by doing the following:

var tmpCdata = $xmlDoc[0].createCDATASection(escape("muzi test 002"));
//i'm also escaping special charactures as well
valueNode[0].appendChild(tmpCdata);

results will be:

<value><![CDATA[muzi%20test%20002]]></value>

Brettz9 (in previous answer) explains how to do this but quite complex, therefore i just wanted to add my solution which is much simpler.
