Xml

Controls how this element's text content is emitted. When set to true, the element content is written inside a CDATA section instead of being emitted as ordinary character data with XML escaping.

Gets or sets the text content stored directly on this XML element. Child elements are not included in this value.

For example, both of the following elements have This is the content as their Content:

<tag1>This is the content</tag1>

<tag2><child1>abc</child1><child2>abc</child2>This is the content</tag2>

Gets or sets this element's content as a 32-bit integer. Setting the property converts the integer to its decimal text representation; getting the property interprets the element's text content as an integer.

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

• A timeout property set to 0, indicating an infinite timeout.
• A hang occurring within an event callback in the application code.
• An internal bug in the Chilkat code causing the hang.

Gets or sets the document type declaration associated with the XML document.

The value represents the document-level DOCTYPE declaration, for example <!DOCTYPE note SYSTEM "note.dtd">.

Controls whether a byte order mark (BOM, also called a preamble) is written when XML is saved to a file. The default is false.

This setting is relevant to encodings for which a BOM can be emitted, such as UTF-8 and UTF-16. It does not affect XML returned as a language string by methods such as GetXml.

Controls whether XML emitted by GetXml and GetXmlSb is compact. When true, unnecessary formatting whitespace and line breaks are omitted. The default is false for backward compatibility.

Controls whether the XML declaration is included when XML is emitted. The default is true. When set to false, output methods such as GetXml and SaveXml omit the declaration.

An XML declaration is the leading construct such as <?xml version="1.0" encoding="utf-8"?>.

Gets or sets the encoding value used in the XML declaration. The default is utf-8. This is a document-level setting and may be accessed from any element in the tree.

When XML is loaded, Chilkat sets this property from the encoding declared by the input XML when one is present. If no encoding is declared, the property is reset to utf-8.

Provides a substitution value for [i] in Chilkat tag paths and ChilkatPath expressions. When a path contains [i], the current value of this property is substituted for I.

Returns true if this element's content consists only of characters allowed in standard Base64 text, with whitespace ignored. Standard Base64 uses A-Z, a-z, 0-9, +, /, and optional trailing = padding.

Provides a substitution value for [j] in Chilkat tag paths and ChilkatPath expressions. When a path contains [j], the current value of this property is substituted for J.

Provides a substitution value for [k] in Chilkat tag paths and ChilkatPath expressions. When a path contains [k], the current value of this property is substituted for K.

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.

Returns the number of attributes on this element.

For example, <tag attr1="value1" attr2="value2">...</tag> has two attributes. Attribute indexes used by methods such as GetAttributeName and GetAttributeValue are zero-based.

Returns the number of direct child elements of this element. Descendants below those children are not included in the count.

Controls case sensitivity for the XML sorting methods. Set to true for case-insensitive string comparisons or false for case-sensitive comparisons.

Controls the standalone pseudo-attribute in the XML declaration. This is a document-level setting and may be accessed from any element in the tree.

Setting this property to true causes the declaration to include standalone="yes".

Gets or sets the element name for this element, including any namespace prefix. For example, the tag for <soapenv:Body> is soapenv:Body.

Use TagNsPrefix and TagUnprefixed when the prefix and local portion are needed separately.

Gets or sets the namespace prefix portion of this element's tag. For soapenv:Envelope, the namespace prefix is soapenv.

Returns the Chilkat tag path needed to reach this element from the document root. If this object currently references the root element, the returned path is the empty string.

Gets or sets the unprefixed portion of this element's tag. For soapenv:Envelope, the unprefixed tag is Envelope.

Use TagNsPrefix to access the prefix separately.

Returns the identifier of the XML tree to which this element belongs. Elements in the same XML document have the same TreeId.

Provides a catch-all string for uncommon XML behaviors. The default is the empty string, which is appropriate for normal use.

Leave this property empty unless Chilkat documentation or support identifies a specific option needed for a specialized interoperability case.

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.

Version of the component/library, such as "10.1.0"

Traverses the subtree rooted at the calling element and concatenates the text content of all elements whose tag equals tag.

Use DecodeContent to recover the encoded bytes.

Returns true for success, false for failure.

Returns true if the child identified by tagPath has content matching pattern; otherwise returns false. caseSensitive controls whether letter case is significant.

The pattern may contain * wildcards, where each asterisk matches zero or more characters.

Evaluates a Chilkat-specific path command that can navigate from the current element, return element content or an attribute value, or move the caller's internal element reference.

This syntax is not XPath. Commands are separated by vertical bars and the expression ends with a return command:

command|command|command|...|returnCommand

Navigation commands include:

• TagName — first direct child having that tag.
• TagName[n] — the indexed direct child having that tag.
• .. — parent.
• ++ / -- — next / previous sibling.
• TagName{Content} — first direct child with that tag and exact content.
• /T/TagName — traverse the subtree and find the first element with that tag.
• /C/TagName,ContentPattern — traverse for a tag whose content matches a wildcard pattern.
• /C/ContentPattern — traverse for any tag whose content matches a wildcard pattern.
• /A/TagName,AttrName,AttrValuePattern — traverse for a tag having a matching attribute value.

The final return command is:

• * — return the current element's content.
• (AttrName) — return an attribute value.
• $ — move this Xml object to the selected element and return an empty string.
