Look at <bookmark/>. The desired output I want is the id with value 5
<xsl:value-of select="//bookmark/ancestor::*[@id][1]/@id"/> only gives me 4
<?xml version="1.0" encoding="UTF-8"?>
<content>
<section id="1">
<section id="2"/>
<section id="3"/>
<section id="9"/>
</section>
<section id="4">

<section id="10"/>
<section id="5"/>
<section>
<bookmark/>
<section id="6">
<section id="7">
<section id="8"/>
</section>

We will then find the XPath of the parent element node of the current node using parent syntax, as shown below screenshot. XPath of Parent node: //input[@id = 'text']//parent::span. It will then select the parent node of the input tag having Id = 'text'. XPath(Parent node): //input[@id = 'text']//parent::*.
Different XPath Axes Used In Selenium Testing ancestor-or-self: This one indicates the context node and all the ancestors relative to the context node, and includes the root node. attribute: This indicates the attributes of the context node. It can be represented with the “@” symbol.
XPath is a mini-language that describes a node pattern to select a set of nodes. Descendant is declared as ' // ' so a child can be defined as a// b, to go deeper into the XML tree descendant gives away.
The way I understand the question and the provided XML document is that the nearest id attribute can also happen on an ancestor (section) element.
In any such case the expressions using ony the preceding:: axis (as specified in the other answers to this question) don't select any node.
One correct XPath expression, which selects the wanted id attribute is:
(//bookmark/ancestor::*[@id][1]/@id
|
//bookmark/preceding::*[@id][1]/@id
)
[last()]
If the id attribute is also allowed on the bookmark element itself, the above XPath expression needs to be modified slightly to accomodate this:
(//bookmark/ancestor-or-self::*[@id][1]/@id
|
//bookmark/preceding::*[@id][1]/@id
)
[last()]
Do note: The ancestor:: and the preceding:: axes do not intersect (do not overlap).
