How can i retrieve all the valid XPATH from all these node?
----------------Sample XML---------------------
<name version="1.0">
<document>
<documentId>0107</documentId>
<NameDetail>
<firstname>SAM</firstname>
<internalreferenceNumber>12345</internalreferenceNumber>
</NameDetail>
<NameDetail>
<firstname>TECHNO</firstname>
<internalreferenceNumber>12346</internalreferenceNumber>
</NameDetail>
</document>
</name>
For the Above XML, the Output would be :
XPATH for name = "/name"
XPATH for documentId = "/document/documentId"
XPATH for firstname = ""/document/NameDetail[1]/firstname"
XPATH for firstname = "/document/NameDetail[2]/firstname"
QTP does not support extracting XPaths from XML documents you would have to do so yourself as plain VBScript perhaps by using Microsoft's XMLDOM object.
Set xmlDoc = CreateObject( "Microsoft.XMLDOM" )

How can I find the nodes that are #is-visible = 'true' using xpath in the document below? Essentially, how can I escape the hyphen
<root>
<year is-visible = 'true'>November 2020</year>
<year ishidden = 'true'>October 1998</year>
</root>
I am new to xpath so I apologize in advance for how basic this question is.
How do I extract just the text from a specific element? For example, how would I extract just "text"
<h1>text</h1>
I tried the following but it seems to select everything including the tags instead of just the text.
//h1/text()
Thanks for your help
`
DocumentBuilderFactory docFactory = DocumentBuilderFactory
.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.parse(new File("src/myFile.xml"));
XPathFactory factory = XPathFactory.newInstance();
XPath xpath = factory.newXPath();
String sessionId = (String) xpath
.evaluate(
"/Envelope/Body/LoginProcessResponse/loginResponse/sessionId",
doc, XPathConstants.STRING);
`
here Envelope is my parent element and i just traversed to the required path(in my case it is sessionid).
Hope it helps
This answer is rather an XSLT answer than an XPath answer, but many of the concepts are nevertheless applicable.
The XPath expression
//h1/text()
seems to be correct. It does select all text() nodes that are direct children of <h1> elements.
But one problem may be, that the XSL default template still copies all the othertext() nodes like described here in the W3C specification:
In the absence of a select attribute, the xsl:apply-templates instruction processes all of the children of the current node, including text nodes.
So to solve your problem, you have to define an explicit template that
ignores all other text() nodes like this:
<xsl:template match="text()" />
If you add this line to your XSL processing, the result will most likely be more pleasant to you.
I am having the following XML structure:
<xml>
<value>b</value>
<objects>
<object>
<value>a</value>
</object>
<object>
<value>b</value>
</object>
</objects>
</xml>
What I want is to select the second object, based on the value in the xml.
This XPath works:
//xml/objects/object[value = 'b']
This XPath does not return results:
//xml/objects/object[value = //xml/value/text()]
Are nested XPath expressions not supported?
They are, but the search within a predicate is always relative to the context you currently in.
Currently you start looking for an <xml/> element which is a child of <object/> and as there is none it will yield an empty result set.
Using ../ or parent::* you can go an axis step up to the parent and can select the required value:
//xml/objects/object[value = ../../value]
I'm trying to parse an xml file
My code looks like:
string path2 = "xmlFile.xml";
XmlDocument xDoc = new XmlDocument();
xDoc.Load(path2);
XmlNodeList xnList = xDoc.DocumentElement["feed"].SelectNodes("entry");
But can't seem to get the listing of nodes. I get the error message- "Use the 'new' keyword to create an object instance." and it seems to be on 'SelectNodes("entry")'
This code worked when I loaded the xml from an rss feed, but not a local file. Can you tell me what I'm doing wrong?
My xml looks like:
<?xml version="1.0"?>
<feed xmlns:media="http://search.yahoo.com/mrss/" xmlns:gr="http://www.google.com/schemas/reader/atom/" xmlns:idx="urn:atom-extension:indexing" xmlns="http://www.w3.org/2005/Atom" idx:index="no" gr:dir="ltr">
<entry gr:crawl-timestamp-msec="1318667375230">
<title type="html">Title 1 text</title>
<summary>summary 1 text text text</summary>
</entry>
<entry gr:crawl-timestamp-msec="1318667375230">
<title type="html">title 2 text</title>
<summary>summary 2 text text text</summary>
</entry>
</feed>
Take the namespace into acount:
XmlNamespaceManager mgr = new XmlNamespaceManager(XDoc.NameTable);
mgr.AddNamespace("atom", "http://www.w3.org/2005/Atom");
XmlNodeList xnList = xDoc.SelectNodes("//atom:entry", mgr);
This is the infamous most FAQ about XPath -- referring to the names of elements that are in a default namespace.
Short answer: search for "XPath default namespace" and understand the problem.
Then use an XmlNamespaceManager instance to add an association between a prefix (say "x") and the default namespace (in your case "http://www.w3.org/2005/Atom").
Finally, replace any Name with x:Name in your XPath expression.
Consider the following xml fragment:
<Obj>
<Name><![CDATA[SomeText]]></Name>
</Obj>
How do I retrieve the "SomeText" value via XPath? I'm using Nauman Leghari's (excellent) Visual XPath tool.
/Obj/Name returns the element
/Obj/Name/text() returns blank
I don't think its a problem with the tool (I may be wrong) - I also read XPath can't extract CDATA (See last response in this thread) - which sounds kinda weird to me.
/Obj/Name/text() is the XPath to return the content of the CDATA markup.
What threw me off was the behavior of the Value property. For an XMLNode (DOM world), the XmlNode.Value property of an Element (with CDATA or otherwise) returns Null. The InnerText property would give you the CDATA/Text content.
If you use Xml.Linq, XElement.Value returns the CDATA content.
string sXml = #"
<object>
<name><![CDATA[SomeText]]></name>
<name>OtherName</name>
</object>";
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml( sXml );
XmlNamespaceManager nsMgr = new XmlNamespaceManager(xmlDoc.NameTable);
Console.WriteLine(#"XPath = /object/name" );
WriteNodesToConsole(xmlDoc.SelectNodes("/object/name", nsMgr));
Console.WriteLine(#"XPath = /object/name/text()" );
WriteNodesToConsole( xmlDoc.SelectNodes("/object/name/text()", nsMgr) );
Console.WriteLine(#"Xml.Linq = obRoot.Elements(""name"")");
XElement obRoot = XElement.Parse( sXml );
WriteNodesToConsole( obRoot.Elements("name") );
Output:
XPath = /object/name
NodeType = Element
Value = <null>
OuterXml = <name><![CDATA[SomeText]]></name>
InnerXml = <![CDATA[SomeText]]>
InnerText = SomeText
NodeType = Element
Value = <null>
OuterXml = <name>OtherName</name>
InnerXml = OtherName
InnerText = OtherName
XPath = /object/name/text()
NodeType = CDATA
Value = SomeText
OuterXml = <![CDATA[SomeText]]>
InnerXml =
InnerText = SomeText
NodeType = Text
Value = OtherName
OuterXml = OtherName
InnerXml =
InnerText = OtherName
Xml.Linq = obRoot.Elements("name")
Value = SomeText
Value = OtherName
Turned out the author of Visual XPath had a TODO for the CDATA type of XmlNodes. A little code snippet and I have CDATA support now.
MainForm.cs
private void Xml2Tree( TreeNode tNode, XmlNode xNode)
{
...
case XmlNodeType.CDATA:
//MessageBox.Show("TODO: XmlNodeType.CDATA");
// Gishu
TreeNode cdataNode = new TreeNode("![CDATA[" + xNode.Value + "]]");
cdataNode.ForeColor = Color.Blue;
cdataNode.NodeFont = new Font("Tahoma", 12);
tNode.Nodes.Add(cdataNode);
//Gishu
break;
CDATA sections are just part of what in XPath is known as a text node or in the XML Infoset as "chunks of character information items".
Obviously, your tool is wrong. Other tools, as the XPath Visualizer correctly highlight the text of the Name element when evaluating this XPath expression:
/*/Name/text()
One can also write a simple XSLT transformation:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">
"<xsl:value-of select="/*/Name"/>"
</xsl:template>
</xsl:stylesheet>
When this transformation is applied on the provided XML document:
<Obj>
<Name><![CDATA[SomeText]]></Name>
</Obj>
the correct result is produced:
"SomeText"
i think the thread you referenced says that the CDATA markup itself is ignored by XPATH, not the text contained in the CDATA markup.
my guess is that its an issue with the tool, the source code is available for download, maybe you can debug it...
See if this helps - http://www.zrinity.com/xml/xpath/
XPATH = /Obj/Name/text()
Just in case you run into a similar issue with jdom2, text() will be an array.
To recover CDATA, use /Obj/Name/text()
A suggestion would be to have another field of the md5 hash of the cdata. You can then use xpath to query based off the md5 with no issue
<sites>
<site>
<name>Google</name>

<urlMD5>ed646a3334ca891fd3467db131372140</urlMD5>

Then you can search:
