Member Function Documentation

◆ CompareDocument()

virtual int32_t System::Xml::Xsl::XsltContext::CompareDocument ( String  baseUri,
String  nextbaseUri 
)
pure virtual

When overridden in a derived class, compares the base Uniform Resource Identifiers (URIs) of two documents based upon the order the documents were loaded by the XSLT processor (that is, the XslTransform class).

Parameters
baseUriThe base URI of the first document to compare.
nextbaseUriThe base URI of the second document to compare.
Returns
An integer value describing the relative order of the two base URIs: -1 if baseUri occurs before nextbaseUri; 0 if the two base URIs are identical; and 1 if baseUri occurs after nextbaseUri.

◆ get_Whitespace()

virtual bool System::Xml::Xsl::XsltContext::get_Whitespace ( )
pure virtual

When overridden in a derived class, gets a value indicating whether to include white space nodes in the output.

Returns
true to check white space nodes in the source document for inclusion in the output; false to not evaluate white space nodes. The default is true.

◆ PreserveWhitespace()

virtual bool System::Xml::Xsl::XsltContext::PreserveWhitespace ( SharedPtr< System::Xml::XPath::XPathNavigator node)
pure virtual

When overridden in a derived class, evaluates whether to preserve white space nodes or strip them for the given context.

Parameters
nodeThe white space node that is to be preserved or stripped in the current context.
Returns
true if the white space is to be preserved; false if the white space is to be stripped.

◆ ResolveFunction()

virtual SharedPtr<IXsltContextFunction> System::Xml::Xsl::XsltContext::ResolveFunction ( String  prefix,
String  name,
ArrayPtr< System::Xml::XPath::XPathResultType ArgTypes 
)
pure virtual

When overridden in a derived class, resolves a function reference and returns an IXsltContextFunction representing the function. The IXsltContextFunction is used at execution time to get the return value of the function.

Parameters
prefixThe prefix of the function as it appears in the XPath expression.
nameThe name of the function.
ArgTypesAn array of argument types for the function being resolved. This allows you to select between methods with the same name (for example, overloaded methods).
Returns
An IXsltContextFunction representing the function.

◆ ResolveVariable()

virtual SharedPtr<IXsltContextVariable> System::Xml::Xsl::XsltContext::ResolveVariable ( String  prefix,
String  name 
)
pure virtual

When overridden in a derived class, resolves a variable reference and returns an IXsltContextVariable representing the variable.

Parameters
prefixThe prefix of the variable as it appears in the XPath expression.
nameThe name of the variable.
Returns
An IXsltContextVariable representing the variable at runtime.
