XSLT 1.0提取HTML文本时单词拼接问题求解

The issue you're facing happens because when you select all text nodes with //body//text() and apply templates directly, XSLT simply concatenates them together without any separators. Text from adjacent elements (like your <u> tags) ends up merged into a single string with no space between words.

Here are two reliable, XSLT 1.0-compatible ways to fix this:

Method 1: Add Spaces Between Text Nodes + Normalize Whitespace #

This approach ensures every text node is followed by a space, then cleans up any extra whitespace (including leading/trailing spaces and multiple spaces in a row):

<content name="body_content">
  <!-- Collect all text nodes with a trailing space -->
  <xsl:variable name="text-with-spaces">
    <xsl:for-each select="//body//text()">
      <!-- Normalize individual text nodes first, then add a separator space -->
      <xsl:value-of select="concat(normalize-space(.), ' ')"/>
    </xsl:for-each>
  </xsl:variable>
  <!-- Clean up the final string to remove extra whitespace -->
  <xsl:value-of select="normalize-space($text-with-spaces)"/>
</content>

How it works: #

• normalize-space(.) trims leading/trailing whitespace from individual text nodes and collapses internal spaces (so " Internet Access " becomes "Internet Access").
• Adding a trailing space guarantees text from separate elements gets separated by at least one space.
• The final normalize-space($text-with-spaces) trims leading/trailing spaces and collapses multiple spaces into one, resulting in clean, properly separated text.

Method 2: Template-Based Approach with Conditional Spaces #

If you prefer using templates over for-each, you can match text nodes and add a leading space (skipping empty text nodes), then clean up the result:

<!-- Template to handle text nodes inside the body -->
<xsl:template match="body//text()">
  <!-- Only process non-empty text nodes -->
  <xsl:if test="normalize-space(.) != ''">
    <xsl:value-of select="concat(' ', normalize-space(.))"/>
  </xsl:if>
</xsl:template>

<content name="body_content">
  <xsl:variable name="prefixed-text">
    <xsl:apply-templates select="//body//text()"/>
  </xsl:variable>
  <!-- Remove the leading space added by the first text node -->
  <xsl:value-of select="substring(normalize-space($prefixed-text), 2)"/>
</content>

Result for Your Input #

Using either method with your sample HTML:

<body>
  <u>Internet Access</u>
  <u>Web</u>
  <u>new cars</u>
</body>

You'll get the desired output:

<content name="body_content">Internet Access Web new cars</content>
