XMLReader擴展是XML Pull解析器。閱讀器充當光標，在文檔流上前進，并在途中的每個節點處停止。與XML Writer配套 ## 編碼 重要的是要注意，在內部，libxml使用UTF-8編碼，因此，檢索到的內容的編碼將始終采用UTF-8編碼 該擴展需要[libxml](https://www.php.net/manual/en/book.libxml.php)PHP擴展 * [XMLReader :: close](https://www.php.net/manual/en/xmlreader.close.php)—關閉XMLReader輸入 * [XMLReader :: expand](https://www.php.net/manual/en/xmlreader.expand.php)—返回當前節點的副本作為DOM對象 * [XMLReader :: getAttribute](https://www.php.net/manual/en/xmlreader.getattribute.php)—獲取命名屬性的值 * [XMLReader :: getAttributeNo](https://www.php.net/manual/en/xmlreader.getattributeno.php)—通過索引獲取屬性的值 * [XMLReader :: getAttributeNs](https://www.php.net/manual/en/xmlreader.getattributens.php)—通過本地名稱和URI獲取屬性的值 * [XMLReader :: getParserProperty](https://www.php.net/manual/en/xmlreader.getparserproperty.php)—指示是否已設置指定的屬性 * [XMLReader :: isValid](https://www.php.net/manual/en/xmlreader.isvalid.php)—指示解析的文檔是否有效 * [XMLReader :: lookupNamespace](https://www.php.net/manual/en/xmlreader.lookupnamespace.php)—前綴的查找名稱空間 * [XMLReader :: moveToAttribute](https://www.php.net/manual/en/xmlreader.movetoattribute.php)—將光標移動到命名屬性 * [XMLReader :: moveToAttributeNo](https://www.php.net/manual/en/xmlreader.movetoattributeno.php)—按索引將光標移動到屬性 * [XMLReader :: moveToAttributeNs](https://www.php.net/manual/en/xmlreader.movetoattributens.php)—將光標移動到命名屬性 * [XMLReader :: moveToElement](https://www.php.net/manual/en/xmlreader.movetoelement.php)—將光標置于當前屬性的父元素上 * [XMLReader :: moveToFirstAttribute](https://www.php.net/manual/en/xmlreader.movetofirstattribute.php)—將光標放在第一個屬性上 * [XMLReader :: moveToNextAttribute](https://www.php.net/manual/en/xmlreader.movetonextattribute.php)—將光標置于下一個屬性上 * [XMLReader :: next](https://www.php.net/manual/en/xmlreader.next.php)—將光標移到下一個節點，跳過所有子樹 * [XMLReader :: open](https://www.php.net/manual/en/xmlreader.open.php)—設置包含要解析的XML的URI * [XMLReader :: read](https://www.php.net/manual/en/xmlreader.read.php)—移動到文檔中的下一個節點 * [XMLReader :: readInnerXml](https://www.php.net/manual/en/xmlreader.readinnerxml.php)—從當前節點檢索XML * [XMLReader :: readOuterXml](https://www.php.net/manual/en/xmlreader.readouterxml.php)—從當前節點（包括自身）檢索XML * [XMLReader :: readString](https://www.php.net/manual/en/xmlreader.readstring.php)—以字符串形式讀取當前節點的內容 * [XMLReader :: setParserProperty-](https://www.php.net/manual/en/xmlreader.setparserproperty.php)設置解析器選項 * [XMLReader :: setRelaxNGSchema](https://www.php.net/manual/en/xmlreader.setrelaxngschema.php)—設置RelaxNG模式的文件名或URI * [XMLReader :: setRelaxNGSchemaSource](https://www.php.net/manual/en/xmlreader.setrelaxngschemasource.php)—設置包含RelaxNG模式的數據 * [XMLReader :: setSchema](https://www.php.net/manual/en/xmlreader.setschema.php)—針對XSD驗證文檔 * [XMLReader :: XML](https://www.php.net/manual/en/xmlreader.xml.php)—設置包含要解析的XML的數據
