This operator is great for checking whether one number divides into another evenly; just check whether the larger number mod the smaller equals zero. As noted, even though the most current version of the XPath language is 2. Construct Meaning string expression This performs an explicit type conversion to a string, which will always give the same result as the implicit conversion described above.

A numeric expression is converted to a string by giving its conventional decimal representation, for example the value String Expressions There are some constructs that are specifically string expressions, but in addition any other kind of expression can be used in a context where a string expression is required: A string that does not represent any number is treated as zero.

Use the and operator to test that all of a series of multiple conditions are true. There are some constructs that are specifically numeric expressions, but in addition any string whose value is convertible to a number can be used as a number. A boolean expression is displayed as one of the strings "true" or "false".

The specific numeric expressions are as follows: Line C multiplies 4 and 3. Comparing Two Values Perhaps the most common test that you can perform on a location path is whether one value is bigger than another Figure 4.

While being off by. When a node-set expression is used in a string context, only the first node of the node-set in document order is used: Line D divides the value of the z element, 11by 3. The alphabetic order of identifiers is the same as the document order of nodes If generate-id A is a leading substring of generate-id Bthen A is an ancestor node of B The identifier is unique not only within the document, but within all documents opened during the run.

There may be any number of arguments two or more. Other boolean operators are not valid. The official specifications for XPath Version 1. XPath offers several functions that, while not explicitly mathematical, return numbers and can be used for any calculations you like: The example shows that 11 mod 4 equals 3, because 4 goes into 11 twice with 3 left over.

Bob DuCharme A Russian translation of this article can be found here. String and text values in Step 3 should be enclosed in single quotes. In this chapter, I will detail many common XPath functions.

The value of a text node is the character content of the node; the value of any other node is the concatenation of all its descendant text nodes.

Mathematical expressions like these can use the full power of XPath to say which element or attribute has a number they need; this stylesheet, however, is more concerned with demonstrating the range of mathematical operations available than with using fancy XPath expressions to retrieve elements and attributes from odd parts of a document.

Explicit conversion can be useful when assigning a value to a variable. The specific string expressions are as follows: If you just want to test that a node set exists regardless of its contentsskip Steps 2—3.

In other cases, I used location paths to extract the contents of a node using xsl: Notice that, in addition to the Overview section of the output, I applied the same height condition to the History section, too.

If expression1 does not contain expression2, it returns the empty string.The expression 9 + 8 represents a single number (17). This expression is a numerical expression, (also called an arithmetic expression).

The expression 9 + x represents a value that can change. If x is 2, then the expression 9 + x has a value of If x is 6, then the expression has a value of XPath Expression Syntax. Contents: Introduction Constants Variable References This document is an informal guide to the syntax of XPath expressions, which are used in SAXON both within XSLT stylesheets, and in the Java API.

For formal specifications, see the XSLT and XPath standards, except where differences are noted here. Following typical math conventions, multiplication and division are performed before addition and subtraction.
