Chilkat VB.NET Xml Class Reference
Xml
A free non-validating XML parser component with encryption and compression features.
Object Creation
(C#)
Chilkat.Xml obj = new Chilkat.Xml();
(VB.NET)
Dim obj As New Chilkat.Xml()
Properties
Cdata As Boolean
When True, causes an XML node's content to be encapsulated in a CDATA section. (VB.NET) Using CDATA in XML (PowerShell) Using CDATA in XML
Content As String
The content of the XML node. It is the text between the open and close tags, not including child nodes. For example:
<tag1>This is the content</tag1>
<tag2><child1>abc</child1><child2>abc</child2>This is the content</tag2>
Because the child nodes are not included, the content of "tag1" and "tag2" are both equal to "This is the content".Content vs. Children: A common misconception explained. (VB.NET) Setting XML Tag and Content (PowerShell) Setting XML Tag and Content
ContentInt As Integer
Set/get the content as an integer.
DocType As String
The DOCTYPE declaration (if any) for the XML document. (VB.NET) Setting the XML DOCTYPE (PowerShell) Setting the XML DOCTYPE
Encoding As String
This is the encoding attribute in the XML declaration, such as "utf-8" or "iso-8859-1". If not present, this property returns an empty string. This property can be set from any node in the XML document and when set, causes the encoding property to be added to the XML declaration. Setting this property does not cause the document to be converted to a different encoding.
LastErrorHtml As String (ReadOnly)
Error information in HTML format for the last method called.
LastErrorText As String (ReadOnly)
Error information in plain-text format for the last method called.
LastErrorXml As String (ReadOnly)
Error information in XML format for the last method called.
NumAttributes As Integer (ReadOnly)
The number of attributes. For example, the following node has 2 attributes:
<tag attr1="value1" attr2="value2"> This is the content</tag>
(VB.NET) Methods for Getting Attributes (PowerShell) Methods for Getting Attributes
NumChildren As Integer (ReadOnly)
The number of direct child nodes contained under this XML node.
SortCaseInsensitive As Boolean
If true (or 1 for ActiveX), then all Sort* methods use case insensitive sorting.
Standalone As Boolean
This is the standalone attribute in the XML declaration. This property can be set from any node in the XML document. A value of True adds a standalone="yes" to the XML declaration:
<?xml ... standalone="yes">
Tag As String
The XML node's tag. (VB.NET) Setting XML Tag and Content (PowerShell) Setting XML Tag and Content
TreeId As Integer (ReadOnly)
Each tree (or XML document) has a unique TreeId. This is the ID of the tree, and can be used to determine if two Xml objects belong to the same tree.
Version As String (ReadOnly)
The version of the XML component, such as "2.0.0".
Methods
Function AccumulateTagContent(ByVal tag As String, ByVal skipTags As String) As String
Accumulates the content of all nodes having a specific tag into a single result string. SkipTags specifies a set of tags whose are to be avoided.

For example, if called with "Big5"for the charset, you would get a string that looks something like this: "=?Big5?B?pHCtsw==?=". The data is Base64-encoded and stored between the last pair of "?" delimiters. Use the DecodeContent method to retrieve the byte data from a B encoded string.
Function ChildContentMatches(ByVal tag As String, ByVal pattern As String, ByVal caseSensitive As Boolean) As Boolean
Return true if a child having a specific tag contains content that matches a wildcarded pattern.
Function ChilkatPath(ByVal pathCmd As String) As String
Follows a series of commands to navigate through an XML document to return a piece of data or update the caller's reference to a new XML document node.
Note: This method not related to the XPath (XML Path) standard in any way.
The pathCmd is formatted as a series of commands separated by vertical bar characters, and terminated with a return-command:
command|command|command|...|returnCommand
A command can be any of the following:
- TagName -- Navigate to the 1st direct child with the given tag.
- TagName[n] -- Navigate to the Nth direct child with the given tag.
- .. -- Navigate up to the parent
- TagName{Content} -- Navigate to the 1st direct child with the given tag having the exact content.
- /T/TagName -- Traverse the XML DOM tree (rooted at the caller) and navigate to the 1st node having the given tag.
- /C/TagName,ContentPattern -- Traverse the XML DOM tree (rooted at the caller) and navigate to the 1st node having the given tag with content that matches the ContentPattern. ContentPattern may use one or more asterisk ('*") characters to represent 0 or more of any character.
- /C/ContentPattern -- Traverse the XML DOM tree (rooted at the caller) and navigate to the 1st node having any tag with content that matches the ContentPattern. ContentPattern may use one or more asterisk ('*") characters to represent 0 or more of any character.
- /A/TagName,AttrName,AttrValuePattern -- Traverse the XML DOM tree
(rooted at the caller) and navigate to the 1st node having the
given tag, and attribute, with the attribute value that matches
the AttrValuePattern. AttrValuePattern may use one or more
asterisk ('*") characters to represent 0 or more of any
character.
The returnCommand can be any of the following:
- * -- Return the Content of the node.
- (AttrName) -- Return the value of the given attribute.
- $ -- Update the caller's internal reference to be the node (arrived at by following the series of commands). Returns an empty string.
