An xsltDocLoaderFunc is a signature for a function which can be registered to load document not provided by the compilation or transformation API themselve, for example when an xsl:import, xsl:include is found at compilation time or when a document() call is made at runtime.
| URI: | the URI of the document to load |
| dict: | the dictionary to use when parsing that document |
| options: | parsing options, a set of xmlParserOption |
| ctxt: | the context, either a stylesheet or a transformation context |
| type: | the xsltLoadType indicating the kind of loading required |
| Returns: | the pointer to the document (which will be modified and freed by the engine later), or NULL in case of error. |
xsltDocLoaderFunc xsltDocDefaultLoader;
xsltDocumentPtr xsltFindDocument (xsltTransformContextPtr ctxt,
xmlDocPtr doc)
Try to find a document within the XSLT transformation context. This will not find document infos for temporary Result Tree Fragments.
| ctxt: | an XSLT transformation context |
| doc: | a parsed XML document |
| Returns: | the desired xsltDocumentPtr or NULL in case of error |
void xsltFreeDocuments (xsltTransformContextPtr ctxt)
Free up all the space used by the loaded documents
| ctxt: | an XSLT transformation context |
void xsltFreeStyleDocuments (xsltStylesheetPtr style)
Frees the node-trees (and xsltDocument structures) of all stylesheet-modules of the stylesheet-level represented by the given @style.
| style: | an XSLT stylesheet (representing a stylesheet-level) |
xsltDocumentPtr xsltLoadDocument (xsltTransformContextPtr ctxt,
const xmlChar * URI)
Try to load a document (not a stylesheet) within the XSLT transformation context
| ctxt: | an XSLT transformation context |
| URI: | the computed URI of the document |
| Returns: | the new xsltDocumentPtr or NULL in case of error |
xsltDocumentPtr xsltLoadStyleDocument (xsltStylesheetPtr style,
const xmlChar * URI)
Try to load a stylesheet document within the XSLT transformation context
| style: | an XSLT style sheet |
| URI: | the computed URI of the document |
| Returns: | the new xsltDocumentPtr or NULL in case of error |
xsltDocumentPtr xsltNewDocument (xsltTransformContextPtr ctxt,
xmlDocPtr doc)
Register a new document, apply key computations
| ctxt: | an XSLT transformation context (or NULL) |
| doc: | a parsed XML document |
| Returns: | a handler to the document |
xsltDocumentPtr xsltNewStyleDocument (xsltStylesheetPtr style,
xmlDocPtr doc)
Register a new document, apply key computations
| style: | an XSLT style sheet |
| doc: | a parsed XML document |
| Returns: | a handler to the document |
void xsltSetLoaderFunc (xsltDocLoaderFunc f)
Set the new function to load document, if NULL it resets it to the default function.
| f: | the new function to handle document loading. |
