Xml VB.NET WinRT Reference Documentation

Xml

Current Version: 9.5.0.73

A free non-validating XML parser component with encryption and compression features.

Object Creation

Dim obj As New Chilkat.Xml()

Properties

Cdata
Cdata As Boolean

When True, causes an XML node's content to be encapsulated in a CDATA section.

More Information and Examples
top
Content
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".

top
ContentInt
ContentInt As Integer

Set/get the content as an integer.

top
DebugLogFilePath
DebugLogFilePath As String

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top
DocType
DocType As String

The DOCTYPE declaration (if any) for the XML document.

More Information and Examples
top
EmitBom
EmitBom As Boolean
Introduced in version 9.5.0.44

If True, then emit the BOM (byte order mark, also known as a preamble) for encodings such as utf-8, utf-16, etc. The defautl value is False. This only applies when writing XML files. It does not apply when getting the XML as a string via the GetXml method.

top
EmitCompact
EmitCompact As Boolean
Introduced in version 9.5.0.64

If True, then GetXml and GetXmlSb emit compact XML. The XML emitted has no unnecessary whitespace, incuding no end-of-lines (CR's and/or LF's). The default value is False, which maintains backward compatibility.

More Information and Examples
top
EmitXmlDecl
EmitXmlDecl As Boolean

If True, then the XML declaration is emitted for methods (such as GetXml or SaveXml) where the XML is written to a file or string. The default value of this property is True. If set to False, the XML declaration is not emitted. (The XML declaration is the 1st line of an XML document starting with "<?xml ...".

top
Encoding
Encoding As String

This is the encoding attribute in the XML declaration, such as "utf-8" or "iso-8859-1". The default is "utf-8". 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.

Calling any of the LoadXml* methods causes this property to be set to the charset found within the XML, if any. If no charset is specified within the loaded XML, then the LoadXml method resets this property to its default value of "utf-8".

top
I
I As Integer
Introduced in version 9.5.0.64

Used in tagPaths (and ChilkatPath). The value of this property is substituted for "i" in "[i]". See the example below..

top
J
J As Integer
Introduced in version 9.5.0.64

Used in tagPaths (and ChilkatPath). The value of this property is substituted for "j" in "[j]". See the example below..

More Information and Examples
top
K
K As Integer
Introduced in version 9.5.0.64

Used in tagPaths (and ChilkatPath). The value of this property is substituted for "k" in "[k]". See the example below..

top
LastErrorHtml
LastErrorHtml As String (ReadOnly)

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorText
LastErrorText As String (ReadOnly)

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorXml
LastErrorXml As String (ReadOnly)

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastMethodSuccess
LastMethodSuccess As Boolean
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of True indicates success, a value of False indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = True and failure = False.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to True. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
NumAttributes
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>

More Information and Examples
top
NumChildren
NumChildren As Integer (ReadOnly)

The number of direct child nodes contained under this XML node.

top
SortCaseInsensitive
SortCaseInsensitive As Boolean

If true (or 1 for ActiveX), then all Sort* methods use case insensitive sorting.

top
Standalone
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">

top
Tag
Tag As String

The XML node's tag.

More Information and Examples
top
TreeId
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.

top
VerboseLogging
VerboseLogging As Boolean

If set to True, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is False. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
Version As String (ReadOnly)

Version of the component/library, such as "9.5.0.63"

top

SearchAllForContent
Function SearchAllForContent(ByVal afterPtr As Xml, ByVal contentPattern As String) As Xml

Returns the first node having content matching the contentPattern. The contentPattern is a case-sensitive string that may contain any number of '*'s, each representing 0 or more occurrences of any character. The search is breadth-first over the sub-tree rooted at the caller. A match is returned only after the search has traversed past the node indicated by afterPtr. To find the 1st occurrence, set afterPtr equal to Nothing. (For the ActiveX implementation, the afterPtr should never be Nothing. A reference to the caller's node should be passed instead.)

To iterate over matching nodes, the returned node can be passed in afterPtr for the next call to SearchAllForContent, until the method returns Nothing.

Returns Nothing on failure

SetBinaryContent
Function SetBinaryContent(ByVal inData As Byte(), ByVal zipFlag As Boolean, ByVal encryptFlag As Boolean, ByVal password As String) As Boolean
