Detailed Description

Class for reading xmp data containing properties relevant to images, and spitting out an array that FormatMetadata accepts.

Note, this is not meant to recognize every possible thing you can encode in XMP. It should recognize all the properties we want. For example it doesn't have support for structures with multiple nesting levels, as none of the properties we're supporting use that feature. If it comes across properties it doesn't recognize, it should ignore them.

The public methods one would call in this class are

parse( $content ) Reads in xmp content. Can potentially be called multiple times with partial data each time.
parseExtended( $content ) Reads XMPExtended blocks (jpeg files only).
getResults Outputs a results array.

Note XMP kind of looks like rdf. They are not the same thing - XMP is encoded as a specific subset of rdf. This class can read XMP. It cannot read rdf.

Constructor & Destructor Documentation

◆ __construct()

XMPReader::__construct ( LoggerInterface $logger = null )

Primary job is to initialize the XMLParser.

Parameters

LoggerInterface | null $logger

Definition at line 136 of file XMP.php.

References $logger, XMPInfo\getItems(), resetXMLParser(), and setLogger().

Member Function Documentation

◆ char()

XMPReader::char	(		$parser,
			$data )

Character data handler Called whenever character data is found in the xmp document.

does nothing if we're in MODE_IGNORE or if the data is whitespace throws an error if we're not in MODE_SIMPLE (as we're not allowed to have character data in the other modes).

As an example, this happens when we encounter XMP like: <exif:DigitalZoomRatio>0/10</exif:DigitalZoomRatio> and are processing the 0/10 bit.

Parameters

resource	$parser	XMLParser reference to the xml parser
string	$data	Character data

Exceptions

RuntimeException On invalid data

Definition at line 495 of file XMP.php.

Referenced by doAttribs().

◆ checkParseSafety()

XMPReader::checkParseSafety ( $content )

private

Check if a block of XML is safe to pass to xml_parse, i.e.

doesn't contain a doctype declaration which could contain a dos attack if we parse it and expand internal entities (T85848).

Parameters

string $content xml string to check for parse safety

Returns: bool true if the xml is safe to parse, false otherwise

References $result, PARSABLE_BUFFERING, PARSABLE_NO, and PARSABLE_OK.

Referenced by parse().

◆ destroyXMLParser()

XMPReader::destroyXMLParser ( )

private

free the XML parser.

Note: It is unclear to me if we really need to do this ourselves or if php garbage collection will automatically free the xmlParser when it is no longer needed.

Definition at line 163 of file XMP.php.

Referenced by parse(), and resetXMLParser().

◆ doAttribs()

XMPReader::doAttribs ( $attribs )

private

Process attributes.

Simple values can be stored as either a tag or attribute

Often the initial "<rdf:Description>" tag just has all the simple properties as attributes.

Example:: <rdf:Description rdf:about="" xmlns:exif="http://ns.adobe.com/exif/1.0/" exif:DigitalZoomRatio="0/10">

Parameters

array $attribs Array attribute=>value

Exceptions

RuntimeException

◆ endElement()

XMPReader::endElement	(		$parser,
			$elm )

Handler for hitting a closing element.

generally just calls a helper function depending on what mode we're in.

Ignores the outer wrapping elements that are optional in xmp and have no meaning.

Parameters

resource	$parser
string	$elm	Namespace . ' ' . element name

Exceptions

RuntimeException

◆ endElementModeIgnore()

XMPReader::endElementModeIgnore ( $elm )

private

When we hit a closing element in MODE_IGNORE Check to see if this is the element we started to ignore, in which case we get out of MODE_IGNORE.

Parameters

string $elm Namespace of element followed by a space and then tag name of element.

Definition at line 586 of file XMP.php.

Referenced by endElement().

◆ endElementModeLi()

XMPReader::endElementModeLi ( $elm )

private

Hit a closing element in MODE_LI (either rdf:Seq, or rdf:Bag ) Add information about what type of element this is.

Note we still have to hit the outer "</property>"

For example, when processing:: <exif:ISOSpeedRatings> <rdf:Seq> <rdf:li>64</rdf:li>

</rdf:Seq> </exif:ISOSpeedRatings>

This method is called when we hit the "</rdf:Seq>". (For comparison, we call endElementModeSimple when we hit the "</rdf:li>")

Parameters

string $elm Namespace . ' ' . element name

◆ endElementModeQDesc()

XMPReader::endElementModeQDesc ( $elm )

private

End element while in MODE_QDESC mostly when ending an element when we have a simple value that has qualifiers.

Qualifiers aren't all that common, and we don't do anything with them.

Parameters

string $elm Namespace and element

Definition at line 752 of file XMP.php.

References list, and saveValue().

Referenced by endElement().

◆ endElementModeSimple()

XMPReader::endElementModeSimple ( $elm )

private

Hit a closing element when in MODE_SIMPLE.

This generally means that we finished processing a property value, and now have to save the result to the results array

For example, when processing: <exif:DigitalZoomRatio>0/10</exif:DigitalZoomRatio> this deals with when we hit </exif:DigitalZoomRatio>.

Or it could be if we hit the end element of a property of a compound data structure (like a member of an array).

Parameters

string $elm Namespace, space, and tag name.

◆ endElementNested()

XMPReader::endElementNested ( $elm )

private

Hit a closing element in MODE_STRUCT, MODE_SEQ, MODE_BAG generally means we've finished processing a nested structure.

resets some internal variables to indicate that.

Note this means we hit the closing element not the "</rdf:Seq>".

For example, when processing:: <exif:ISOSpeedRatings> <rdf:Seq> <rdf:li>64</rdf:li>

</rdf:Seq> </exif:ISOSpeedRatings>

This method is called when we hit the "</exif:ISOSpeedRatings>" tag.

Parameters
