expression would return account numbers of all accounts that have a balance subelement, regardless of its value XPath provides several functions that can be used as part of predicates, including testing the position of the current node in the sibling order and counting the number of nodes matched For example, the path expression /bank-2/account/[customer/count()> 2] returns accounts with more than 2 customers Boolean connectives and and or can be used in predicates, while the function not( ) can be used for negation The function id( foo ) returns the node (if any) with an attribute of type ID and value foo The function id can even be applied on sets of references, or even strings containing multiple references separated by blanks, such as IDREFS For instance, the path /bank-2/account/id(@owner) returns all customers referred to from the owners attribute of account elements The | operator allows expression results to be unioned For example, if the DTD of bank-2 also contained elements for loans, with attribute borrower of type IDREFS identifying loan borrower, the expression /bank-2/account/id(@owner) | /bank-2/loan/id(@borrower) gives customers with either accounts or loans However, the | operator cannot be nested inside other operators An XPath expression can skip multiple levels of nodes by using // For instance, the expression /bank-2//name nds any name element anywhere under the /bank-2 element, regardless of the element in which it is contained This example illustrates the ability to nd required data without full knowledge of the schema Each step in the path need not select from the children of the nodes in the current node set In fact, this is just one of several directions along which a step in the path may proceed, such as parents, siblings, ancestors and descendants We omit details, but note that // , described above, is a short form for specifying all descendants, while speci es the parent

Querying and Transformation
<xsl:template match= /bank-2/customer > <customer> <xsl:value-of select= customer-name /> </customer> </xsl:template> <xsl:template match= /> Figure 1010 Using XSLT to wrap results in new XML elements
replace a large number of font declarations in the HTML page The XML Stylesheet Language (XSL) was originally designed for generating HTML from XML, and is thus a logical extension of HTML style sheets The language includes a general-purpose transformation mechanism, called XSL Transformations (XSLT), which can be used to transform one XML document into another XML document, or to other formats such as HTML1 XSLT transformations are quite powerful, and in fact XSLT can even act as a query language XSLT transformations are expressed as a series of recursive rules, called templates In their basic form, templates allow selection of nodes in an XML tree by an XPath expression However, templates can also generate new XML content, so that selection and content generation can be mixed in natural and powerful ways While XSLT can be used as a query language, its syntax and semantics are quite dissimilar from those of SQL A simple template for XSLT consists of a match part and a select part Consider this XSLT code: <xsl:template match= /bank-2/customer > <xsl:value-of select= customer-name /> </xsl:template> <xsl:template match= /> The xsl:template match statement contains an XPath expression that selects one or more nodes The rst template matches customer elements that occur as children of the bank-2 root element The xsl:value-of statement enclosed in the match statement outputs values from the nodes in the result of the XPath expression The rst template outputs the value of the customer-name subelement; note that the value does not contain the element tag Note that the second template matches all nodes This is required because the default behavior of XSLT on subtrees of the input document that do not match any template is to copy the subtrees to the output document XSLT copies any tag that is not in the xsl namespace unchanged to the output Figure 1010 shows how to use this feature to make each customer name from our example appear as a subelement of a <customer> element, by placing the xsl:value-of statement between <customer> and </customer>
1 The XSL standard now consists of XSLT and a standard for specifying formatting features such as fonts, page margins, and tables Formatting is not relevant from a database perspective, so we do not cover it here
