XML XPath Not Working

View 2 RepliesXElement And An XPath Expression ?
Feb 1, 2010I have an XElement and an XPath expression that selects a node from it. It works fine in the original program that I wrote it in but doesnt work if I paste it to another program. I've checked the references and import statements.
I think the problem might be that the original program had the code within the class of a wpf window while it was moved to a abstract class where it doesnt work.[code...]
Asp.net - Why Is This XPath Expression Getting Too Much Data

Reading A XML File - XPath?
Apr 24, 2009There are multiple occurances of the PLUS_BORROWER data. For each occurence of PLUS_BORROWER, I want to save the CREDIT_SCORE and DAYTIME_PHONE_NBR when the Type= And SOCIAL_SECURITY_NBR are certain values. Then I want to execute a loop and extract the Credit_Score and Daytime_Phone_Nbrs.
<PLUS_BORROWER Type="Primary"> <SOCIAL_SECURITY_NBR>123459999</SOCIAL_SECURITY_NBR> <CREDIT_SCORE ModelName="Emperica">793</CREDIT_SCORE> <DAYTIME_PHONE_NBR>4077889999</DAYTIME_PHONE_NBR> <DAYTIME_PHONE_EXT>101</DAYTIME_PHONE_EXT></PLUS_BORROWER>
I have the following code that will pull off the first PLUS_BORROWER if the Type='Primary', but I am having trouble expanding it.
oExtraData.Load(myXMLFile) 'only select nod with type attribute equal primary Dim oNode As Xml.XmlNode = oExtraData.SelectSingleNode("//PLUS_BORROWER[@Type='Primary']") 'get credit score node Dim scoreNode As Xml.XmlNode = oNode.SelectSingleNode("CREDIT_SCORE") MsgBox("I have the Primary") MsgBox("Credit score is " & scoreNode.InnerText)

XPath - How To Get Value Of Specific DIV From HTML
Oct 28, 2011I'm trying to get the value of a specific <div> from an html.

Best thing for me is if I am able to access the needed <div> using something like XPATH so I can target only those I need.

Xml - Can't Get XPath Query To Return The Right Nodeset?
Jun 2, 2011I've got an xml file that looks like this:
<Records>

<table>[code].....
What I need is to select all the ROW nodes, across all records, so I'm using something like this:
rowiterator = Me.XMLDocument.CreateNavigator.Evaluate("//table/Row")
which is working, but it returns a NodeIterator that only contains the first Row node in the first record!? As far as I can tell, that's the proper syntax for an xpath expression of "return all Row nodes with a parent table name anywhere in the document".

Mar 26, 2010Using VB.Net,I have an XmlNode object, xNode.I need to select an attribute of this node if it has a particular value.
e.g. xNode.SelectSingleNode(".[@attr1='1']")
I would expect this statement to return the attribute "attr1", only if it has a value of "1". However, I get an error - Expression must evaluate to a node-set.When I tried this - xNode.SelectSingleNode("@attr1[@attr1='1']")It always returns Nothing, even if the attribute has a value of 1.

Xml - Duplicate Selection In Text() XPath Selector
Jan 7, 2010I'm trying to select all nodes with text that contain a certain word (ex: Company) because the word needs to have a register mark.
Here is part of the XHTML (this <p> is inside a table cell).
<p>
<strong>
<a style="color:#0E5A8B; text-decoration:none" target="_blank" href="http://www.trekk.com">
[Code]....
My goal is to just select the 2nd one, the <span> tag and am not sure why <p> tag is also being selected. If it selects <p>, but why wouldn't it also select the <strong> or <a>, and why not the <table> or <td> that contain the <p>?
C# - Identify Duplicate Nodes In XPath 1.0 Using A XPathNavigator To Evaluate?
Jun 27, 2012I am trying to identify duplicate serial numbers from the following xml using XPath 1.0 and then evaluating it in .Net using an XPathNavigator.
<?xml version="1.0" encoding="utf-16"?>
<Inventory xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Items>
[code]....
I tried to do this by evaluating this
//Items/Item/SerialNumber
expression in a custom XSLT Context Function (implementing IXsltContextFunction like this MSDN example) in .Net but the Invoke function gets called one result at a time so I have no visibility of the other results to find duplicates.
1) Is there a way of doing this using a single XPath 1.0 expression?
2) Is there a way of passing in an array of elements into a single Invoke call of the custom XSLT Context Function class? I'm working in VB.Net but am happy with any C# examples anyone can share.

Xml - Find The String Position (index) From A XPath Statement?
May 7, 2009I'm looking for the actual index position in a given source string.I have the following string
"<a>
<b>zyx</b>
<b>wvu</b>
[code]....
I'm loading that string into a .NET XmlDocument object. Carriage Returns and Line Fees may be a factor here.
Dim xmlSearchText As New XmlDocument()
xmlSearchText.LoadXml(SearchTextBox.Text)
Dim selectedNode As XmlNode = xmlSearchText.SelectSingleNode(txtSearch.Text)
The following XPath Statement could be used to find the 3rd node:
a/b[.='tsr']
However, I need it to return a string index of 23 rather than the ordinal position of 3.
XPath When A Root Node And Element Have Different Name Space Attributes?

dim bodynode as XMLNode=XML.SelectSingleNode(//ns:body,nsmngr)
where "nsmngr" is the namespacemanger created by me and "ns" is the name space of the "parent node" (which the "body" node inherits) added to the namespace manager as "ns"
