第一篇文章。我希望它符合提问的规则。XmlDocument返回特定节点/元素的困难
我有点困扰xml文档(它的API返回了Xml)。现在它使用了大量基于互联网(http的)安全措施,我已经努力了,现在我能够返回顶层的未嵌套的节点。
但是有几个节点嵌套在这些下面,我需要返回一些这些值。
我设置使用XMLDocument来做到这一点,我对使用XPath不感兴趣。
我还应该注意到我使用的是.Net 4.5环境。
示例XML
<?xml version="1.0" encoding="utf-8"?>
<results>
<Info xmlns="http://xmlns.namespace">
<title>This Title</title>
<ref>
<SetId>317</SetId>
</ref>
<source>
<name>file.xxx</name>
<type>thisType</type>
<hash>cc7b99599c1bebfc4b8f12e47aba3f76</hash>
<pers>65.97602</pers>
<time>02:20:02.8527777</time>
</source>
....... Continuation which is same as above
好了,所以上面是获取从API返回的XML,现在,我可以回到标题节点没有问题。我还想返回的是元素中的任何节点值,例如pers节点值。但我只想返回一个(因为现有的xml中有很多下降)
请注意,Info节点中有一个xmlns,它可能不允许我返回值。
因此,这里是我的代码提前
using (var response = (HttpWebResponse) request.GetResponse())
{
//Get the response stream
using (Stream stream = response.GetResponseStream())
{
if (stream != null)
{
var xDoc = new XmlDocument();
var nsm = new XmlNamespaceManager(xDoc.NameTable);
nsm.AddNamespace("ns", XmlNamespace);
//Read the response stream
using (XmlReader xmlReader = XmlReader.Create(stream))
{
// This is straight forward, we just need to read the XML document and return the bits we need.
xDoc.Load(xmlReader);
XmlElement root = xDoc.DocumentElement;
var cNodes = root.SelectNodes("/results/ns:Info", nsm);
//Create a new instance of Info so that we can store any data found in the Info Properties.
var info = new Info();
// Now we have a collection of Info objects
foreach (XmlNode node in cNodes)
{
// Do some parsing or other relevant filtering here
var title = node["title"];
if (title != null)
{
info.Title = title.InnerText;
_logger.Info("This is the title returned ############# {0}", info.Title);
}
//This is the bit that is killing me as i can't return the any values in the of the sub nodes
XmlNodeList sourceNodes = node.SelectNodes("source");
foreach (XmlNode sn in sourceNodes)
{
XmlNode source = sn.SelectSingleNode("source");
{
var pers = root["pers"];
if (pers != null) info.pers = pers.InnerText;
_logger.Info("############FPS = {0}", info.pers);
}
}
}
}
