In order to have a site search on your website, you usually first have to index your site. What this means is that you run our indexing script that will crawl through your website, grabbing most of the searchable text, and storing it in a MySQL database. Not stored are tags such as script, body, paragraph, head, CSS styles, JavaScript, etc. In fact NO tags are stored, nor is the data between most tags' start tag and end tag. But the content in the head tag's title and description is stored, and so is the page URL, and everything that isn't tags between start tags and end tags of body tags, paragraph tags, headings tags like <H1>, etc.

Having said that, we also have a script Search Website without Indexing Using XPATH and PHP that goes through the above process on the fly on each web page as well as searching the pages.

Most of our XPATH scripts use the PHP DOM extension and PHP 5. The DOM extension is enabled by default in most PHP installations, so the following should work fine—it does for us. The DOM extension allows you to operate on XML documents through the DOM API with PHP 5. It supports XPATH 1.0, which our scripts use extensively. XPATH has been around awhile. What is it? XPath is a syntax for defining parts of an XML document (or an HTML or XHTML one). It uses path expressions to navigate in documents. It contains a library of standard functions.

The DOMXPath class has the DOMDocument property and several very useful methods: DOMXPath::__construct, DOMXPath::evaluate (which evaluates the given XPath expression and returns a typed result if possible or a DOMNodeList containing all nodes matching the given XPath expression), DOMXPath::query (which evaluates and executes the given XPath expression and returns a DOMNodeList containing all nodes matching the given XPath expression), DOMXPath::registerNamespace (which is necessary to use XPath to handle documents which have default namespaces described in the xmlns declaration which in the case of a sitemap is in the urlset tag), and DOMXPath::registerPhpFunctions. Most XML files seem to have no xmlns declaration (e.g., PAD files), therefore needing no namespace registration.

The above apps are about searching website and/or web page files. Websites can be built out of several file types. We concentrate on HTML, HTM, and PHP file extensions in our scripts. You can quickly see just how powerful XPATH is (check out the above links) when you look at what it can empower: site indexing and searching, listing all the internal or external (offsite) URLs or videos or audios or images or page titles or page descriptions on all the hundreds of pages on a website. There's even a Search Website without Indexing Using XPATH and PHP script that does a site search of site X while on site Y without even doing any site indexing first. Indexing is grabbing the page content on a site's pages, dumping the HTML tags, and storing it in a database—usually MySQL. Like we say: this XPATH stuff is powerful magic!
