The substring function returns the substring of the first argument starting at the position specified in the second argument with length specified in the third argument. For example, substring("12345",2,3) returns "234". If the third argument is not specified, it returns the substring starting at the position specified in the second argument and continuing to the end of the string. For example, substring("12345",2) returns "2345". More precisely, each character in the string (see [3.6 Strings]) is considered to have a numeric position: the position of the first character is 1, the position of the second character is 2 and so on. The returned substring contains those <a href="libxml-SAX.html#characters">characters</a> for which the position of the character is greater than or equal to the second argument and, if the third argument is specified, less than the sum of the second and third arguments; the comparisons and addition used for the above follow the standard IEEE 754 rules. Thus: - substring("12345", 1.5, 2.6) returns "234" - substring("12345", 0, 3) returns "12" - substring("12345", 0 div 0, 3) returns "" - substring("12345", 1, 0 div 0) returns "" - substring("12345", -42, 1 div 0) returns "12345" - substring("12345", -1 div 0, 1 div 0) returns ""</p> <div class="variablelist"><table border="0"><col align="left" /><tbody><tr><td><span class="term"><i><tt>ctxt</tt></i>:</span></td><td>the XPath Parser context</td></tr><tr><td><span class="term"><i><tt>nargs</tt></i>:</span></td><td>the number of arguments</td></tr></tbody></table></div><h3><a name="xmlXPathSumFunction" id="xmlXPathSumFunction"></a>Function: xmlXPathSumFunction</h3><pre class="programlisting">void xmlXPathSumFunction (<a href="libxml-xpath.html#xmlXPathParserContextPtr">xmlXPathParserContextPtr</a> ctxt, <br /> int nargs)<br /> </pre><p>Implement the sum() XPath function number sum(node-set) The sum function returns the sum of the values of the nodes in the argument node-set.</p> <div class="variablelist"><table border="0"><col align="left" /><tbody><tr><td><span class="term"><i><tt>ctxt</tt></i>:</span></td><td>the XPath Parser context</td></tr><tr><td><span class="term"><i><tt>nargs</tt></i>:</span></td><td>the number of arguments</td></tr></tbody></table></div><h3><a name="xmlXPathTrailing" id="xmlXPathTrailing"></a>Function: xmlXPathTrailing</h3><pre class="programlisting"><a href="libxml-xpath.html#xmlNodeSetPtr">xmlNodeSetPtr</a> xmlXPathTrailing (<a href="libxml-xpath.html#xmlNodeSetPtr">xmlNodeSetPtr</a> nodes1, <br /> <a href="libxml-xpath.html#xmlNodeSetPtr">xmlNodeSetPtr</a> nodes2)<br /> </pre><p>Implements the EXSLT - Sets trailing() function: node-set set:trailing (node-set, node-set) @nodes1 and @nodes2 are sorted by document order, then #xmlXPathTrailingSorted is called.</p> <div class="variablelist"><table border="0"><col align="left" /><tbody><tr><td><span class="term"><i><tt>nodes1</tt></i>:</span></td><td>a node-set</td></tr><tr><td><span class="term"><i><tt>nodes2</tt></i>:</span></td><td>a node-set</td></tr><tr><td><span class="term"><i><tt>Returns</tt></i>:</span></td><td>the nodes in @nodes1 that follow the first node in @nodes2 in document order, @nodes1 if @nodes2 is NULL or empty or an empty node-set if @nodes1 doesn't contain @nodes2</td></tr></tbody></table></div><h3><a name="xmlXPathTrailingSorted" id="xmlXPathTrailingSorted"></a>Function: xmlXPathTrailingSorted</h3><pre class="programlisting"><a href="libxml-xpath.html#xmlNodeSetPtr">xmlNodeSetPtr</a> xmlXPathTrailingSorted (<a href="libxml-xpath.html#xmlNodeSetPtr">xmlNodeSetPtr</a> nodes1, <br /> <a href="libxml-xpath.html#xmlNodeSetPtr">xmlNodeSetPtr</a> nodes2)<br /> </pre><p>Implements the EXSLT - Sets trailing() function: node-set set:trailing (node-set, node-set)</p> <div class="variablelist"><table border="0"><col align="left" /><tbody><tr><td><span class="term"><i><tt>nodes1</tt></i>:</span></td><td>a node-set, sorted by document order</td></tr><tr><td><span class="term"><i><tt>nodes2</tt></i>:</span></td><td>a node-set, sorted by document order</td></tr><tr><td><span class="term"><i><tt>Returns</tt></i>:</span></td><td>the nodes in @nodes1 that follow the first node in @nodes2 in document order, @nodes1 if @nodes2 is NULL or empty or an empty node-set if @nodes1 doesn't contain @nodes2</td></tr></tbody></table></div><h3><a name="xmlXPathTranslateFunction" id="xmlXPathTranslateFunction"></a>Function: xmlXPathTranslateFunction</h3><pre class="programlisting">void xmlXPathTranslateFunction (<a href="libxml-xpath.html#xmlXPathParserContextPtr">xmlXPathParserContextPtr</a> ctxt, <br /> int nargs)<br /> </pre><p>Implement the translate() XPath function string translate(string, string, string) The translate function returns the first argument string with occurrences of <a href="libxml-SAX.html#characters">characters</a> in the second argument string replaced by the character at the corresponding position in the third argument string.
