Have you tried something like:

//a[contains(@prop, "Foo")]

I've never used the contains function before but suspect that it should work as advertised...

For the code above...
//*[contains(@prop,'foo')]

blocks|key|1752914|text|试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1752915|//acontains(@prop，'foo')|1752916|这应该适用于文档中的任何"a“标记|1752917|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

try this:

//a[contains(@prop,'foo')]

that should work for any "a" tags in the document

blocks|key|1538120|text|//a[contains(@prop,'Foo')]|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|1538121|如果我使用这个XML来返回结果，那么它就会起作用。|unstyled|1538122|<bla>

<pre><code>//a[contains(@prop,'Foo')]
</code></pre>

Works if I use this XML to get results back.

<pre><code>&lt;bla&gt;
 &lt;a prop="Foo1"&gt;a&lt;/a&gt;
 &lt;a prop="Foo2"&gt;b&lt;/a&gt;
 &lt;a prop="3Foo"&gt;c&lt;/a&gt;
 &lt;a prop="Bar"&gt;a&lt;/a&gt;
&lt;/bla&gt;
</code></pre>

Edit: 
Another thing to note is that while the XPath above will return the correct answer for that particular xml, if you want to guarantee you only get the "a" elements in element "bla", you should as others have mentioned also use

<pre><code>/bla/a[contains(@prop,'Foo')]
</code></pre>

This will search you all "a" elements in your entire xml document, regardless of being nested in a "blah" element

<pre><code>//a[contains(@prop,'Foo')] 
</code></pre>

I added this for the sake of thoroughness and in the spirit of stackoverflow. :)

blocks|key|1753024|text|John+C是最接近的，但是XPath区分大小写，所以正确的XPath应该是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1753025|/bla/a[contains(@prop,+'Foo')]|code-block|syntax|javascript|1753026|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

John C is the closest, but XPath is case sensitive, so the correct XPath would be:

<pre><code>/bla/a[contains(@prop, 'Foo')]
</code></pre>

<pre><code>descendant-or-self::*[contains(@prop,'Foo')]
</code></pre>

Or:

<pre><code>/bla/a[contains(@prop,'Foo')]
</code></pre>

Or:

<pre><code>/bla/a[position() &lt;= 3]
</code></pre>

Dissected:

<pre><code>descendant-or-self::
</code></pre>

The Axis - search through every node underneath and the node itself. It is often better to say this than //. I have encountered some implementations where // means anywhere (decendant or self of the root node). The other use the default axis.

<pre><code>* or /bla/a
</code></pre>

The Tag - a wildcard match, and /bla/a is an absolute path.

<pre><code>[contains(@prop,'Foo')] or [position() &lt;= 3]
</code></pre>

The condition within [ ]. @prop is shorthand for attribute::prop, as attribute is another search axis. Alternatively you can select the first 3 by using the position() function.

blocks|key|1538365|text|此XPath将为您提供属性包含'Foo‘的所有节点，而不考虑节点名称或属性名称：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1538366|//attribute::*[contains(.,+'Foo')]/..|code-block|syntax|javascript|1538367|当然，如果您更感兴趣的是属性本身的内容，而不一定是它们的父节点，那么只需删除/。|1538368|//attribute::*[contains(.,+'Foo')]|1538369|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

This XPath will give you all nodes that have attributes containing 'Foo' regardless of node name or attribute name:

<pre><code>//attribute::*[contains(., 'Foo')]/..
</code></pre>

Of course, if you're more interested in the contents of the attribute themselves, and not necessarily their parent node, just drop the /..

<pre><code>//attribute::*[contains(., 'Foo')]

blocks|key|1538438|text|如果您还需要匹配链接本身的内容，请使用text()：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1538439|//a[contains(@href,"/some_link")][text()="Click+here"]|offset|length|style|CODE|1538440|entityMap^0|0|0|1I|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@$D|L|E|M|F|G]]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

If you also need to match the content of the link itself, use text():

<code>//a[contains(@href,"/some_link")][text()="Click here"]</code>

Given this XML, what XPath returns all elements whose <code>prop</code> attribute contains <code>Foo</code> (the first three nodes):

<pre><code>&lt;bla&gt;
 &lt;a prop="Foo1"/&gt;
 &lt;a prop="Foo2"/&gt;
 &lt;a prop="3Foo"/&gt;
 &lt;a prop="Bar"/&gt;
&lt;/bla&gt;
</code></pre>

What is the correct XPath for choosing attributes that contain "foo"?

给定此XML，XPath将返回其prop属性包含Foo (前三个节点)的所有元素：<bla> <a prop="Foo1"/> <a prop="Foo2"/> <a prop="3Foo"/> <a prop="Bar"/></bla>
