1544 Sometimes XML data should be loaded from some other source than a file, i.e. HTTP URL; also you may want to load XML data from file using non-standard functions, i.e. to use your virtual file system facilities or to load XML from GZip-compressed files. All these scenarios require loading document from memory. First you should prepare a contiguous memory block with all XML data; then you have to invoke one of buffer loading functions. These functions will handle the necessary encoding conversions, if any, and then will parse the data into the corresponding XML tree. There are several buffer loading functions, which differ in the behavior and thus in performance/memory usage:</p> 1539 Sometimes XML data should be loaded from some other source than a file, i.e. HTTP URL; also you may want to load XML data from file using non-standard functions, i.e. to use your virtual file system facilities or to load XML from GZip-compressed files.

This can significantly reduce the memory required for documents with many PCDATA nodes. To retrieve the data you can use <code>xml_node::value()</code> on the element nodes or any of the higher-level functions like <code>child_value</code> or <code>text</code>.

2008 The internal representation of the document is a tree, where each node has a list of child nodes (the order of children corresponds to their order in the XML representation), and additionally element nodes have a list of attributes, which is also ordered. Several functions are provided in order to let you get from one node in the tree to the other. These functions roughly correspond to the internal representation, and thus are usually building blocks for other methods of traversing (i.e. XPath traversals are based on these functions).</p> 2006 The internal representation of the document is a tree, where each node has a list of child nodes (the order of children corresponds to their order in the XML representation), and additionally element nodes have a list of attributes, which is also ordered.

3521 <p>If the task at hand is to select a subset of document nodes that match some criteria, it is possible to code a function using the existing traversal functionality for any practical criteria. However, often either a data-driven approach is desirable, in case the criteria are not predefined and come from a file, or it is inconvenient to use traversal interfaces and a higher-level DSL is required. There is a standard language for XML processing, XPath, that can be useful for these cases. pugixml implements an almost complete subset of XPath 1.0. Because of differences in document object model and some performance implications, there are minor violations of the official specifications, which can be found in <a href="#xpath.w3c">Conformance to W3C specification</a>.

Because of differences in document object model and some performance implications, there are minor violations of the official specifications, which can be found in <a href="#xpath.w3c">Conformance to W3C specification</a>. The rest of this section describes the interface for XPath functionality. Please note that if you wish to learn to use XPath language, you have to look for other tutorials or manuals; for example, you can read <a href="https://www.w3schools.com/xml/xpath_intro.asp">W3Schools XPath tutorial</a> or <a href="https://www.w3.org/TR/xpath-10/">the XPath 1.0 specification</a>.</p>

3531 Because an XPath node can be either a node or an attribute, there is a special type, <code>xpath_node</code>, which is a discriminated union of these types. A value of this type contains two node handles, one of <code>xml_node</code> type, and another one of <code>xml_attribute</code> type; at most one of them can be non-null. The accessors to get these handles are available:</p> 3556 Because an XPath node can be either a node or an attribute, there is a special type, <code>xpath_node</code>, which is a discriminated union of these types.

3652 While compiling expressions is fast, the compilation time can introduce a significant overhead if the same expression is used many times on small subtrees. If you&#8217;re doing many similar queries, consider compiling them into query objects (see <a href="#xpath.query">Using query objects</a> for further reference).
