The functions in <code><a class="el" href="classTXMPMeta.html" title="API for access to the XMP Toolkit core services.">TXMPMeta</a></code> such as <code><a class="el" href="classTXMPMeta.html#a06a3241c7fa5df87f61dff02fca23a0c" title="GetProperty() reports whether a property exists, and retrieves its value.">TXMPMeta::GetProperty()</a></code>, <code><a class="el" href="classTXMPMeta.html#ac64a4251d157937f69b73f2ffac4f7cc" title="GetArrayItem() provides access to items within an array.">TXMPMeta::GetArrayItem()</a></code>, and <code><a class="el" href="classTXMPMeta.html#a885ef7127b897e349f71fa493ace3c94" title="GetStructField() provides access to fields within a nested structure.">TXMPMeta::GetStructField()</a></code> provide easy access to top level simple properties, items in top level arrays, and fields of top level structs. They are not as convenient for more complex things, such as fields several levels deep in a complex struct, or fields within an array of structs, or items of an array that is a field of a struct. You can use these utility functions to compose these paths, which you can then pass to the property access functions. You can also compose paths to top-level array items or struct fields so that you can use the binary accessors such as <code><a class="el" href="classTXMPMeta.html#ae4e8ee4cc7441bb9464dac87f2d74650" title="GetProperty_Int() retrieves the value of an integer property as a C long integer...">TXMPMeta::GetProperty_Int()</a></code>.</p>
<p>You can use these functions is to compose a complete path expression, or all but the last component. For example, suppose you have a property that is an array of integers within a struct. You can access one of the array items like this:</p>
<pre>
SXMPUtils::ComposeStructFieldPath ( schemaNS, "Struct", fieldNS, "Array", &path );
SXMPUtils::ComposeArrayItemPath ( schemaNS, path, index, &path );
exists = xmpObj.GetProperty_Int ( schemaNS, path, &value, &options );
</pre><p>You could also use this code if you want the string form of the integer:</p>
<pre>
SXMPUtils::ComposeStructFieldPath ( schemaNS, "Struct", fieldNS, "Array", &path );
xmpObj.GetArrayItem ( schemaNS, path, index, &value, &options );
</pre><dl class="note"><dt><b>Note:</b></dt><dd>It might look confusing that the <code>schemaNS</code> is passed in all of the calls above. This is because the XMP Toolkit keeps the top-level "schema" namespace separate from the rest of the path expression. </dd></dl>

<p>API for access to the XMP Toolkit utility services. </p>
<p><code><a class="el" href="classTXMPUtils.html" title="API for access to the XMP Toolkit utility services.">TXMPUtils</a></code> is a template class which must be instantiated with a string class such as <code>std::string</code>. See the instructions in XMP.hpp, and the Overview for a discussion of the overall architecture of the XMP API.</p>
<p>This class defines helper functions that support the basic metadata manipulation provided by <code><a class="el" href="classTXMPMeta.html" title="API for access to the XMP Toolkit core services.">TXMPMeta</a></code>. All of the functions are static; that is, you call them directly from the concrete class (<code>SXMPUtils</code>), which is never itself instantiated.</p>
<p>General categories of utilities include:</p>
<ul>
<li>Composing complex path expressions, which you can then pass to the property access functions in <code><a class="el" href="classTXMPMeta.html" title="API for access to the XMP Toolkit core services.">TXMPMeta</a></code> </li>
<li>Converting between binary and string forms of property values </li>
<li>Manipulating date/time values </li>
<li>Encoding and decoding base-64 strings </li>
<li>JPEG file handling </li>
<li>Editing aids for creating a user interface for the XMP Toolkit </li>
</ul>

<p>The XMP template can be used to add, replace or delete properties from the working XMP object. This function replaces the previous <code>AppendProperties()</code> function, which is no longer available. The actions that you specify determine how the template is applied. Each action can be applied individually or combined; if you do not specify any actions, the properties and values in the working XMP object do not change.</p>
<p>These actions are available: </p>
<ul>
<li>Clear (<code><a class="el" href="XMP__Const_8h.html#ab04a0655cd1e3bcac5e8f48c18df1a57a9dac536fe6ee25de76d45bf6615abd46" title="Perform a Clear operation, keep named properties and delete everything else.">kXMPTemplate_ClearUnnamedProperties</a></code>): Deletes top-level properties. Any top-level property that is present in the template (even with empty value) is retained. All other top-level properties in the working object are deleted.</li>
</ul>
<ul>
<li>Add (<code><a class="el" href="XMP__Const_8h.html#ab04a0655cd1e3bcac5e8f48c18df1a57a145c259f83048b811c7b35bc3b339c42" title="Perform an Add operation, add properties if they don't already exist.">kXMPTemplate_AddNewProperties</a></code>): Adds new properties to the working object if the template properties have values. See additional detail below.</li>
</ul>
<ul>
<li>Replace (<code><a class="el" href="XMP__Const_8h.html#ab04a0655cd1e3bcac5e8f48c18df1a57aae2e0fe43295736a15f0bb76ffe02544" title="Perform a Replace operation, add new properties and modify existing ones.">kXMPTemplate_ReplaceExistingProperties</a></code>): Replaces the values of existing top-level properties in the working XMP if the value forms match those in the template. Properties with empty values in the template are ignored. If combined with Clear or Add actions, those take precedence; values are cleared or added, rather than replaced.</li>
</ul>
<ul>
<li>Replace/Delete empty (<code><a class="el" href="XMP__Const_8h.html#ab04a0655cd1e3bcac5e8f48c18df1a57a81e1b6fd067fc9ad62bc803c98701bd5" title="Similar to Replace, also delete if the template has an empty value.">kXMPTemplate_ReplaceWithDeleteEmpty</a></code>): Replaces values in the same way as the simple Replace action, and also deletes properties if the value in the template is empty. If combined with Clear or Add actions, those take precedence; values are cleared or added, rather than replaced.</li>
</ul>
<ul>
<li>Include internal (<code><a class="el" href="XMP__Const_8h.html#ab04a0655cd1e3bcac5e8f48c18df1a57a872d2b769e775e281984cc63e28714ea" title="Do all properties, default is just external properties.">kXMPTemplate_IncludeInternalProperties</a></code>): Performs specified action on internal properties as well as external properties. By default, internal properties are ignored for all actions.</li>
</ul>
<p>The Add behavior depends on the type of property: </p>
<ul>
<li>
If a top-level property is not in the working XMP, and has a value in the template, the property and value are added. Empty properties are not added. </li>
<li>
If a property is in both the working XMP and template, the value forms must match, otherwise the template is ignored for that property. </li>
<li>
If a struct is present in both the working XMP and template, the individual fields of the template struct are added as appropriate; that is, the logic is recursively applied to the fields. Struct values are equivalent if they have the same fields with equivalent values. </li>
<li>
If an array is present in both the working XMP and template, items from the template are added if the value forms match. Array values match if they have sets of equivalent items, regardless of order. </li>
<li>
Alt-text arrays use the <code>xml:lang</code> qualifier as a key, adding languages that are missing. </li>
</ul>
<p>Array item checking is n-squared; this can be time-intensive if the Replace option is not specified. Each source item is checked to see if it already exists in the destination, without regard to order or duplicates. Simple items are compared by value and <code>xml:lang</code> qualifier; other qualifiers are ignored. Structs are recursively compared by field names, without regard to field order. Arrays are compared by recursively comparing all items. </p>

<p>Path syntax allows two forms of "content addressing" to select an item in an array of alternatives. The form used in this function lets you select an item in an alt-text array based on the value of its <code>xml:lang</code> qualifier. The other form of content addressing is shown in <code><a class="el" href="classTXMPUtils.html#a458f8e8729e2334fe54ca8f691a9db23" title="ComposeFieldSelector() composes a path expression to select an alternate item by...">ComposeFieldSelector()</a></code>.</p>
<p>The returned string is in the form <code>ns:arrayName[@xml:lang='langName']</code>, where "ns" is the prefix for the schema namespace</p>
<p>This function provides a path expression that is explicitly and only for a specific language. In most cases, <code><a class="el" href="classTXMPMeta.html#af9531b949a462f5663b1f3fd99464c19" title="SetLocalizedText() modifies the value of a selected item in an alt-text array.">TXMPMeta::SetLocalizedText()</a></code> and <code><a class="el" href="classTXMPMeta.html#aeefe49bbf669770d769f4fe0ea566bd0" title="GetLocalizedText() retrieves information about a selected item in an alt-text array...">TXMPMeta::GetLocalizedText()</a></code> are preferred, because they provide extra logic to choose the appropriate language and maintain consistency with the 'x-default' value.</p>
