英文:
Xpath doesn't detect text with nbsp
问题
<tr>
<td align="left" width="200">
<p>文档已上传：是</p>
</td>
</tr>
我无法在文本中找到带有 &nbsp; 的元素。下面的XPath表达式不起作用，我尝试了许多在线建议，但仍未成功。提醒：我需要的是整个文本，而不仅仅是其中的子字符串。
//p[contains(text(), '文档已上传：是')]
英文:
<tr>
<td align="left" width="200">
<p>Document Uploaded:&nbsp;Yes</p>
</td>
</tr>
I'm unable to locate the element with &nbsp; in the text. The below XPath expression does not not work and I've tried so many other suggestions online but have not been successful yet. FYI: I need the entire text not just a substring of it.
//p[contains(text(), 'Document Uploaded: Yes')]

尝试使用以下代码：
//p[contains(text(), 'Document Uploaded: Yes')]
&#160; 是命名字符引用 &nbsp; 的数字字符引用（参见维基百科）。它还可以用在 XML/XSLT 文档开头的 DOCTYPE 声明中，以使 &nbsp; 可用：
<!DOCTYPE stylesheet [
<!ENTITY nbsp " " >
]>
英文:
Try using
//p[contains(text(), 'Document Uploaded:&#160;Yes')]
&#160; is the Numeric character reference for the Named character reference &nbsp; (See Wikipedia). It can also be used in a DOCTYPE declaration at the beginning of an XML/XSLT document to make &nbsp; usuable:
<!DOCTYPE stylesheet [
<!ENTITY nbsp "&#160;" >
]>

使用：
//p[. = 'Document Uploaded: Yes']
基于 XSLT 的验证：
此 XSLT 转换仅评估上述 XPath 表达式并输出评估结果：
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:copy-of select="//p[. = 'Document Uploaded: Yes']"/>
</xsl:template>
</xsl:stylesheet>
当应用于提供的 XML 文档时：
<!DOCTYPE stylesheet [
<!ENTITY nbsp " " >
]>
<tr>
<td align="left" width="200">
<p>Document Uploaded: Yes</p>
</td>
</tr>
将产生所需的正确结果：
<p>Document Uploaded: Yes</p>
英文:
Use:
//p[. = 'Document Uploaded:&#xA0;Yes']
XSLT - based verification:
This XSLT transformation just evaluates the above XPath expression and outputs the result of the evaluation:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:copy-of select=
"//p[. = 'Document Uploaded:&#xA0;Yes']"/>
</xsl:template>
</xsl:stylesheet>
When applied on the provided XML document:
<!DOCTYPE stylesheet [
<!ENTITY nbsp "&#160;" >
]>
<tr>
<td align="left" width="200">
<p>Document Uploaded:&nbsp;Yes</p>
</td>
</tr>
the wanted, correct result is produced:
<p>Document Uploaded: Yes</p>

以下是翻译好的部分：
另一个解决方案是绕过字符处理：
//p[contains(text(),'Document Uploaded:')][contains(text(),'Yes')]
使用一个 XPath 来查找同时包含你所需字符串的元素。如果你希望更严格，可以使用 starts-with 和 ends-with。
另一种方法是不要通过文本来查找这个项目，而是获取元素并在 Java 中处理它。
我不能提供一个完整的示例，因为我需要查看更多的 HTML，但大致过程如下：
- 找到一个固定的锚点，比如在你的 HTML 表格中其他容易识别的元素
- 从那个锚点创建一个 XPath，使用
following-sibling::、parent::或者following::（你明白我的意思） - 以找到这个Document Uploaded:元素 - 在 Java 中将它设置为你的 XPath，使用
findElement方法。 - 在 Java 中：
myElement.getText()
我认为 Selenium 足够智能，可以去掉 nbsp 字符 - 但即使它不去掉，你仍然会得到一个文本字符串来确认你的文档上传状态。
英文:
Odd one this! The other answers mentioned above should word.
An alternative solution is to work around the character:
//p[contains(text(), 'Document Uploaded:')][contains(text(), 'Yes')]
Use an xpath that looks for an element that contains both string you need. If you need it to be more rigid, you can use starts-with and ends-with.
Another approach is don't find this item by text but rather get the element and process it in Java.
I can't give a working example as I would need to see more html but the process would be:
- Find an fixed anchor point e.g. something else in your html table you can identify easily
- Create an xpath from that anchor with
following-sibling::orparent::orfollowing::(you get the idea) - whatever to find thisDocument Uploaded:element - set that as your xpath in java with
findElement. - In java:
myElement.getText()
I think Selenium is smart enough to strip out the nbsp character - but even if it does not you'll still have a text string confirming your document upload status.
